Foreword
Sanitation and drinking water –
at the heart of human health and development
2008 is the International Year of Sanitation. Accordingly, this report by the
WHO/UNICEF Joint Monitoring Programme for Water Supply and Sanitation (JMP)
has sanitation as its focus.
The importance of sanitation is indisputable. It is a crucial stepping stone to better
health: sanitation offers us the opportunity to save the lives of 1.5 million children
a year who would otherwise succumb to diarrhoeal diseases, and to protect the
health of many more. It is fundamental to gender equity as it protects women’s
dignity. And it is key to economic development: investments in sanitation protect
investments made in other sectors, such as education and health, and bring
measurable economic returns.
However, the data in this report show that the world is not on track to meet the
MDG sanitation target, and 2.5 billion people still lack access to improved sanitation,
including 1.2 billion who have no facilities at all. The message is clear: We need to
greatly accelerate progress in sanitation, particularly in sub-Saharan Africa and
Southern Asia. The number of people who still do not have access to improved
sanitation is staggering, and we know that the disease, loss of earnings and
indignity lock huge numbers of people into poverty.
But the news is not all bad. Although greater impetus is needed, the data show
that people are choosing to move up the ‘sanitation ladder’, abandoning open
defecation and revealing a demand for sanitation facilities.
In the case of drinking water supply, the news is good. For the first time, the number
of people without improved drinking water has dropped below one billion. More
than half of the global population now benefits from piped water reaching their
homes, and the numbers using unimproved water supplies are going down. But
we must maintain our efforts and galvanize the global community to continue to
advance, focusing on those countries and regions, such as sub-Saharan Africa, which
are struggling to stay on track.
The overall message from this report is positive. Progress can be made, and the
sanitation and drinking water battle can be won. Our agencies are proud to present
this report on status, and to press forward together.

The purpose of this report
This report details global progress towards the Millennium
Development Goal (MDG) target for drinking water and
sanitation, and what these trends suggest for the remainder of
the Water for Life Decade 2005-2015.
connections into a dwelling, plot or yard; other improved
water sources; and unimproved sources.
In recognition of the large sanitation deficit, and the
declaration of 2008 as the International Year of Sanitation,
the report has a special focus on sanitation. It opens with a
review of the current status of sanitation and an assessment of
progress towards the sanitation target included in the MDGs. New data are also presented on the time taken to collect
drinking water. The data show the proportion of people
that spend more than 30 minutes on a single water-hauling
trip and are thus likely to compromise their daily water
consumption. In addition, survey data on who usually fetches
water are presented to show how this burden is distributed
among women, men, girls and boys.
The report also introduces a separate assessment of global,
regional and country progress using the ‘sanitation ladder’ –
a new way of analysing sanitation practices that highlights
trends in using improved, shared and unimproved sanitation
facilities and the trend in open defecation. Trends in drinking
water coverage are presented in a similar format. They are
disaggregated in a ‘drinking water ladder’, which shows
the percentage of the world population that uses piped
Finally, the report provides a new perspective on progress.
The country, regional and global estimates, starting on page
41, include a statistic on the proportion of the population that
gained access to improved drinking water and sanitation since
1990. The intention is to recognize those countries that have
made significant progress despite major obstacles, including
low levels of coverage in 1990, rapid population growth or
both.

2008: International Year of Sanitation
INTERNATIONAL YEAR OF
SANITATION
2008
Without improved sanitation, people suffer
from ill health, lost income, inconvenience and
indignity. Yet billions of people around the
world lack basic sanitation. In recognition of the
urgent need for greater political awareness and
action on sanitation, the United Nations General
Assembly declared 2008 as the International
Year of Sanitation. The goal is to raise awareness
and accelerate progress towards the MDG target
of halving the proportion of people without
sustainable access to basic sanitation by 2015.
The five key messages of the International Year of
Sanitation are:
• Sanitation is vital for human health
• Sanitation generates economic benefits
• Sanitation contributes to dignity and social
development
• Sanitation helps the environment
• Sanitation is achievable!

Figure 2 summarizes trends in the steps of
the sanitation ladder for the various MDG
regions. It shows that sanitation coverage
in the developing world increased from 41
per cent in 1990 to 53 per cent in 2006. This
means that an additional 1.1 billion people in
developing regions are now using improved
sanitation facilities. Steep coverage gains in
South-eastern and Eastern Asia, which both
saw 17 percentage-point increases, contributed
significantly to this improvement. Sub-Saharan
Africa recorded the least progress, with use of
improved sanitation increasing from 26 per cent
in 1990 to 31 per cent in 2006.
Unimproved
Shared
In this report, sanitation coverage is presented
as a four-step ladder that includes the
proportion of the population:
• practising open defecation
• using an unimproved sanitation facility
• using a shared sanitation facility
• using an improved sanitation facility.
Open defecation: Defecation in fields,
forests, bushes, bodies of water or other
open spaces, or disposal of human faeces
with solid waste.
Unimproved sanitation facilities: Facilities
that do not ensure hygienic separation
of human excreta from human contact.
Unimproved facilities include pit latrines
without a slab or platform, hanging latrines
and bucket latrines.
Shared sanitation facilities: Sanitation
facilities of an otherwise acceptable type
shared between two or more households.
Shared facilities include public toilets.
Improved
Readers of the BMJ (British Medical Journal)
recently identified sanitation as “the most
important medical advance since 1840.”
Nevertheless, only 62 per cent of the world’s
population has access to improved sanitation
– that is, uses a sanitation facility that ensures
hygienic separation of human excreta from
human contact. A further 8 per cent shares an
improved facility with one or more households,
and another 12 per cent uses an unimproved
sanitation facility – one that does not ensure
hygienic separation of excreta from human
contact. The remaining 18 per cent of the
world’s population practises indiscriminate or
open defecation.
Open
defEcation
An new way to look at sanitation practices: Improved sanitation facilities: Facilities that
ensure hygienic separation of human excreta
from human contact. They include:
• Flush or pour-flush toilet/latrine to:
- piped sewer system
- septic tank
- pit latrine
• Ventilated improved pit (VIP) latrine
• Pit latrine with slab
• Composting toilet.
The sanitation ladder shows that more than half of
those without improved sanitation already use some
type of sanitation facility.

Figure 2 shows that open defecation is declining in all regions:
dropping from 24 per cent worldwide in 1990 to 18 per cent in 2006.
Open defecation is still most widely practised in Southern Asia and
sub-Saharan Africa – by 48 per cent and 28 per cent of the population,
respectively. In contrast, open defecation is common among only 3
per cent of the people in Eastern Asia. In four of the seven developing
regions for which data are available, less than 10 per cent of the
population practises open defecation.

since 1990
Between 1990 and 2006, the proportion
of people without improved sanitation
decreased by only 8 percentage points.
Without an immediate acceleration in
progress, the world will not achieve
even half the MDG sanitation target by
2015. Based on current trends, the total
population without improved sanitation
in 2015 will have decreased only slightly
since 1990, to 2.4 billion.

The MDG target for water
and sanitation requires that
indicators to measure progress
be disaggregated by urban and
rural populations. Although the
target – halving the proportion
of people without sustainable
access to safe drinking water
and basic sanitation – reflects
total populations, progress
towards the target is based on
the sum of progress in both
urban and rural areas. This
report therefore highlights
urban and rural disparities that
would otherwise be masked by
total numbers.

Improved sanitation facilities:
Facilities that ensure hygienic separation
of human excreta from human contact.
They include:
• Flush or pour-flush toilet/latrine to:
- septic tank
- pit latrine
• Ventilated improved pit latrine
• Pit latrine with slab
• Composting toilet
Sixty-two per cent of the world’s population uses
improved sanitation, up from 54 per cent in 1990. The
lowest coverage is found in sub-Saharan Africa, where
only 31 per cent of the population uses improved
sanitation, up just 5 percentage points since 1990.
Improved sanitation coverage is also low in Southern
Asia, but significant efforts since 1990 have moved
regional coverage from 21 per cent to 33 per cent in
2006 – more than doubling the number of people who
use improved sanitation facilities.
The richest are three times more likely to use
improved sanitation than the poorest

Despite increases in coverage, more than 2.5 billion
people remain without improved sanitation. Almost
1.8 billion of them – 70 per cent – live in Asia; 22 per

At least two thirds of the population in
34 countries are not using improved
sanitation facilities. Only eight of these
countries are outside sub-Saharan Africa.
Despite low sanitation coverage, it is worth
noting that, in these 34 countries, 274
million people gained access to improved
sanitation since 1990. Moreover, several of
these countries managed to double their
1990 sanitation coverage.
The use of improved sanitation facilities is
substantially lower among the poor than
the rich. An analysis across 38 developing
countries shows that the poorest 20 per
cent of the population has only one third
the access to improved sanitation as the
richest quintile. In sub-Saharan Africa,
inequality is higher still: The richest 20 per
cent of the population is five times more
likely to use an improved sanitation facility
than the poorest 20 per cent.

THE SANITATION LADDER: SHARED
Shared sanitation
Shared sanitation facilities:
Sanitation facilities of an otherwise acceptable type that
are shared between two or more households, including
public toilets.
Note: Data on shared sanitation facilities presented here exclude
shared facilities that are unimproved, such as shared pit latrines
without a slab or shared open pits.
Sanitation facilities that are shared among households – whether
fully public or accessible only to some – are not considered ‘improved’
facilities, according to the definition used for the MDG indicator.
While the use of shared sanitation does reflect demand, limited data
confirm the widely held perception that many of these facilities,
especially public ones, fail to ensure hygienic separation of human
excreta from human contact. Serious concern has also been expressed
about the actual accessibility of such facilities throughout the day and
about the security of users, especially at night. Further research on the
nature and acceptability of shared facilities is needed.
The proportion of people using shared sanitation facilities is 10 per
cent or less in all developing regions except sub-Saharan Africa, where
they are used by 18 per cent of the
population.
Recent household surveys, namely
Multiple Indicator Cluster Surveys
(MICS) and Demographic and Health
Surveys (DHS), provide information
about the number of households
sharing a sanitation facility. The
analysis in Table 3 shows that, for
most countries in which at least 10
per cent of the urban population
shares a sanitation facility of
an acceptable technology, the
majority share a facility with five
or fewer households. An exception
is Ghana, where a considerably
larger proportion of households in
both urban and rural areas share
sanitation facilities with more than
five households.

Shared sanitation remains largely
an urban phenomenon
The 2006 coverage estimates confirm that more
than two thirds of shared sanitation users are
urban dwellers. In Eastern Asia, 92 per cent of
the users of shared facilities are found in urban
areas. In urban areas of sub-Saharan Africa, every
third person uses a shared sanitation facility. This
finding reflects the limited sanitation options
available in many congested cities and towns, an
issue that is likely to become increasingly serious
if urban and peri-urban populations continue to
grow at current rates.
Sharing sanitation facilities is more
prevalent in regions with the lowest
sanitation coverage

THE SANITATION LADDER: UNIMPROVED
Unimproved sanitation facilities
Unimproved sanitation facilities:
Facilities that do not ensure hygienic
separation of human excreta from human
contact. Included in this category are pit
latrines without a slab or platform, hanging
latrines and bucket latrines. Also included are
improved facilities that lack adequate disposal,
such as pour-flush toilets that discharge
directly into open drains, ditches or other
bodies of water.
Use of an unimproved sanitation facility represents the
first step up the sanitation ladder. The user is no longer
defecating in the open, but has moved to some sort
of facility, albeit one that fails to effectively separate
human excreta from human contact. Nevertheless, it
shows demand for sanitation. Unimproved sanitation
facilities can be upgraded to improved sanitation. For
this reason, their users constitute a critical audience for
health promotion activities.
Eight out of ten
users of unimproved
facilities live in
rural areas.
Use of unimproved sanitation facilities is four times
higher in rural than in urban areas

THE SANITATION LADDER: OPEN DEFECATION
Open defecation
Open defecation:
The practice of open defecation is decreasing
Defecation in fields, forests, bushes,
bodies of water or other open spaces, or
disposal of human faeces with solid waste.
The proportion of people practising open defecation has
decreased in developing regions, dropping from 31 per
cent in 1990 to 23 per cent in 2006. Almost two thirds of
those who practise open defecation – 778 million people –
live in Southern Asia. Despite the drop in percentage terms,
population growth means that the number of people
who practise open defecation today is little changed
from 1990. In sub-Saharan Africa, 221 million people are
defecating in the open, the second largest total for any
region. Nevertheless, the proportion of the population
practising open defecation is 20 percentage points higher
in Southern Asia.
Open defecation is the last recourse for those
without any form of sanitation – those at the
bottom of the sanitation ladder who must endure
the daily indignity of defecating in open, often
publicly accessible, spaces. Open defecation is
of fundamental importance to development
because of the health hazard it poses to anyone
living nearby. If some members of a community
continue to defecate in the open, then the
whole community is at greater risk of diarrhoeal
diseases, worm infestations and hepatitis than
people living in communities where open
defecation is not practised.
Nearly one third (31 per cent) of the world’s rural
population practises open defecation. In Southern Asia,
the figure is a remarkable 63 per cent. The relatively
high proportion of the rural population who practise
open defecation in Latin America and the Caribbean (23
per cent) and Western Asia (14 per cent) is noteworthy,
especially in contrast with the urban areas of these regions.
Open defecation is six times more frequent in rural than in urban areas

Open defecation is predominantly
a rural practice
Eighteen per cent of the world’s population – 1.2
billion people – are practising open defecation.
However, only 13 per cent of them live in urban
areas. It is mostly a rural phenomenon, practised
by over a billion rural inhabitants. In developing
regions, more than one out of three rural dwellers
defecate in the open. The one exception is Eastern
Asia, where the practice is uncommon.

Many countries are making rapid progress, despite formidable odds
The MDG target requires halving the proportion of people without sustainable
access to safe drinking water and basic sanitation by 2015. For countries that had a
high proportion of people without access in the baseline year 1990, the task is much
greater than for countries that already had high coverage levels. Moreover, many of
the countries that started with low coverage had the additional challenge of rapid
population growth. Tables 6 and 7 show countries that have made rapid progress
between 1990 and 2006,1 despite one or both challenges.
Table 7 lists the six countries that have progressed most rapidly among countries not on
track to meet the sanitation target. These are all countries with low coverage baselines
in 1990. Five of them are in sub-Saharan Africa, illustrating the results of accelerated
efforts being made in that region.

DRINKING WATER

Piped into dwelling, plot or yard
In this report, drinking water coverage is
presented as a three-step ladder that includes
the proportion of the population using:
• unimproved drinking water sources
• improved drinking water sources other
than piped water
• water piped into a dwelling, plot or yard.
OTHER
IMPROVED
Drinking water supply can be broken down
into three categories, which are illustrated in
the form of a ‘drinking water ladder’ similar to
that developed for sanitation. The category
‘improved drinking water sources’ includes
sources that, by nature of their construction
or through active intervention, are protected
from outside contamination, particularly faecal
matter. These include piped water in a dwelling,
plot or yard, and other improved sources.
‘Unimproved sources’ make up the third part of
the ladder.
UNIMPROVED
The drinking water ladder
22
Unimproved drinking water sources:
Unprotected dug well, unprotected spring,
cart with small tank/drum, tanker truck, and
surface water (river, dam, lake, pond, stream,
canal, irrigation channels), bottled water.
Other improved drinking water sources:
Public taps or standpipes, tube wells or
boreholes, protected dug wells, protected
springs and rainwater collection.
Piped water on premises: Piped household
water connection located inside the user’s
dwelling, plot or yard.

Improved drinking water coverage in sub-Saharan Africa is still
considerably lower than in other regions. Nevertheless, it has increased
from 49 per cent in 1990 to 58 per cent in 2006, which means that an
additional 207 million Africans are now using safe drinking water.

Urban-rural disparities in drinking water coverage
The MDG target for water and

measure progress be disaggregated
by urban and rural populations. This
report therefore highlights urban

Piped water on premises:
Piped connections into a dwelling,

Solid progress is being made in piped
drinking water coverage
Good progress has been made in the use of piped
drinking water on premises, which represents
the highest rung of the drinking water ladder
where health gains are maximized. Use of piped
drinking water has risen by six percentage points
since 1990, reaching 54 per cent in 2006. While
this may seem modest, it represents an increase
of one billion people. This progress is impressive.
However, piped drinking water remains largely an
urban privilege: 2.5 billion urban inhabitants use
a piped drinking water connection on premises,
compared to only 1.1 billion people in rural areas.

Other improved sources:
Sources of drinking water likely to be
protected from outside contamination,
particularly faecal matter, but excluding
piped connections into dwelling, plot
or yard. They include public taps or
standpipes, tube wells or boreholes,
protected dug wells, protected springs
and rainwater collection.
Use of other improved drinking water sources
remains high globally and has increased since
1990. Populations in Southern Asia rely heavily
on these drinking water sources, where use has
increased from 54 per cent to 65 per cent since
1990. In sub-Saharan Africa, use has increased
from 33 per cent to 42 per cent during the
same period. In South-eastern Asia, use of other
improved drinking water sources has declined
slightly, though more than half the population (54
per cent) depends on them. In all other regions,
use of these sources is decreasing – most notably
in Northern Africa, where use declined from 30 per
cent in 1990 to 14 per cent in 2006.
Rural dwellers are more than twice as likely as urban dwellers
to rely on other improved sources of drinking water

Unimproved drinking water sources:
Unprotected dug wells, unprotected

bottled water, tanker truck, and surface
water (river, dam, lake, pond, stream,
canal, irrigation channels).
The lowest rung of the drinking water ladder
is use of unimproved drinking water sources.
Thirteen per cent of the world’s population
– 884 million people – now consumes
drinking water from unimproved sources. This
represents a reduction of 10 percentage points
since 1990. Sub-Saharan Africa has the largest
population using unimproved water sources,
but figures have dropped for this region from
51 per cent in 1990 to 42 per cent in 2006.
Oceania is the only developing region that has
failed to lower use of unimproved drinking
water sources since 1990. Half of the 9.2
million people in that region continue to use
unimproved sources.
884 million people – about half of whom live in Asia –

Use of bottled water is a growing
phenomenon
Surveys show that bottled water is a significant
source of drinking water in some developing
countries. The water comes in both bottles and
plastic sachets and is usually packaged by private
enterprises, both large and small. Tap water is
often resold in bottles by public water vendors.
The WHO/UNICEF Joint Monitoring Programme
for Water Supply and Sanitation (JMP) considers
bottled water a source of improved drinking
water only when another improved source is
also used for cooking and personal hygiene.
For countries where information on the use of
alternative sources is not yet available, bottled
water is considered on a case-by-case basis.
The JMP will be analysing the role of bottled
water in an upcoming report on the safety and
quality of drinking water.

Countries facing exceptional challenges deserve recognition
As described on page 20, this report recognizes the efforts of countries that face the
greatest challenges in meeting the MDG water and sanitation target, due to either low
baseline coverage levels or rapid population growth. Table 10 lists ten countries on
track to meet the MDG drinking water target that have made the most rapid progress
between 1990 and 2006.2 Seven of these countries are in sub-Saharan Africa.
Table 11 lists the five countries that have progressed most rapidly among countries not
on track to meet the drinking water target. All of them had low coverage baselines in
1990, and all are in sub-Saharan Africa.

EXPANDING DATA COLLECTION

Household water treatment
The WHO/UNICEF Joint Monitoring Programme
for Water Supply and Sanitation has played an
increasingly important role in improving the
indicators and methods used for monitoring
national and global drinking water supply and
sanitation. In 2004, work began on developing
a series of questions related to this topic that
are recommended for inclusion in all national
household surveys. The dual aims of this exercise
are to increase coherence among surveys over
time and the comparability of estimates among
countries. This set of questions has already been
adopted by two of the major household survey
programmes in the developing world – that is,
the UNICEF-supported Multiple Indicator Cluster
Surveys and the USAID-supported Demographic
and Health Surveys. The work was carried out
in collaboration with national and international
authorities on household surveys as well as
academics and sector specialists. This set of ‘Core
Questions’ can be found on the JMP website
(www.wssinfo.org). Work in this area will continue
as other indicators are developed and adopted at
national and international levels.
The set of Core Questions
includes questions related
to household drinking
water treatment practices
and on the gender
aspects of drinking
water collection. The
latest round of MICS,
conducted in 2005 and
2006, and a series of DHS
carried out since 2005
have enabled the JMP to
include the findings from
these questions in this
report. The inclusion of a
question on household
water treatment was
particularly timely since it
provides national baseline
data for over 70 countries,
now that household water
treatment is being more
widely promoted.
Table 12
Unhygienic handling of water during transport or within the
home can contaminate previously safe water. A high percentage
of people could therefore benefit from effective household water
treatment and safe storage practices. Such household-level
interventions can be very effective in preventing disease if they
are used correctly and consistently.
Two main household surveys used by the JMP now include
questions on household water treatment. Results from recent
surveys conducted in 35 countries show that a variety of
treatment methods are used. Additional evidence can be
obtained and a trend analysis carried out as more surveys
become available over time.
The JMP is currently undertaking an investigation to explore
issues related to household water treatment technologies, with
a view to evaluating their potential role in providing measurable
access to a safe and sustainable drinking water supply.

Gender dimensions
of hauling water
Some recent household surveys included
the question, “Who usually goes to the
source to fetch water for the household?”
The findings, presented in Figure 33,
confirm the anecdotal evidence that
women shoulder the bulk of the watercollecting responsibility when drinking
water is not available on premises.
Women are more than twice as likely
as men to go and fetch drinking water.
Interestingly, the findings also suggest
that children (boys and girls) play a
relatively small role in water collection
(only 11 per cent of households report
that children are the main water haulers).
Moreover, men appear to play a larger
role in collecting water than they were
previously given credit for: 1 out of 4
households report that men are usually
responsible for collecting water.

Safe disposal of children’s faeces
In many developing countries, young children defecate either in or close to home, or in
diapers and potties. Infant and child excreta often ends up contaminating soil, drains
and water bodies, either through direct disposal or defecation, or through the washing
of diapers, potties and children in areas without safe wastewater disposal.
As with open defecation, unsafe disposal of child excreta poses a health risk to anyone
living or playing nearby. When left in the open in the yard or direct vicinity of the
household, child faeces, which may carry a higher pathogen load than adult faeces, pose
a particular risk for young children, whose play areas frequently overlap with disposal
areas. Safe disposal of children’s faeces is therefore at least as important as stopping
open defecation.

Time spent to go to the source, collect
water and come back
When drinking water is not available in the home or
close to it, the time taken to collect water (that is, to
go to the source, stand in line, fill water containers
and return home) is critical in determining whether
a household can obtain enough water for drinking,
food preparation and personal hygiene.
Studies have found that if the time spent collecting
drinking water is between 3 and 30 minutes, the
amount collected is fairly constant and suitable to
meet basic needs – defined as between 15 and 25
litres per person per day. However, if the total time
taken per round trip exceeds 30 minutes, people
tend to collect less water, thus compromising their
basic drinking water needs. The MDG indicator does
not include a measure for time taken to collect water.
However, some argue that, because it is a factor in
drinking water use, the time needed to collect water
should be considered when determining whether a
source is ‘improved’ or not.
Data from 35 recent household surveys show that
18 per cent of the population in sub-Saharan Africa
relies on an improved drinking water source that is
more than 30 minutes away.
*According to data from the latest household survey on file.

JMP methodology
The JMP
The WHO/UNICEF Joint Monitoring Programme for Water
Supply and Sanitation is the official United Nations
mechanism tasked with monitoring progress towards the
MDG drinking water and sanitation target. In fulfilling this
mandate, the JMP publishes updated estimates every two
years on the various types of drinking water sources and
sanitation facilities being used worldwide.
This JMP report presents global, regional and national
estimates of the use of improved drinking water sources
and improved sanitation facilities in 2006. These coverage
estimates show what proportion of the population
remained without improved drinking water sources and
improved sanitation in 2006 and what the increase in use
has been since the MDG baseline in 1990. In addition, the
changes in coverage between 1990 and 2006 are used to
assess progress towards the 2015 MDG targets for drinking
water and sanitation.
In line with the MDG indicator definition, which stipulates
‘use of improved facilities’ as a proxy for ‘access to
improved facilities’, the JMP measures and reports on the
actual use of facilities. It is worth noting that the household
surveys on which the JMP relies also measure ‘use’ and not
‘access’ – since access involves many additional criteria
other than use. Measurability of many of these other
criteria at the national scale, which is the scale required by
the JMP, poses a huge challenge.
Data sources and the JMP database
For each country, survey and census data are plotted on
a time scale from 1980 to the present. A linear trend line,
based on the least-squares method, is drawn through
these data points to estimate coverage for 1990 and 2006.
The total coverage estimates are based on the aggregate
of the population-weighted urban and rural coverage
numbers, divided by the total population.
Trend analysis at the country level has been carried out for
the following categories:
Drinking water:
- Piped water into dwelling, plot or yard
- Improved drinking water sources
Sanitation:
- Improved sanitation facilities
- Open defecation
The coverage estimates for improved sanitation
facilities presented in this report are discounted by the
proportion of the population that shared an improved
type of sanitation facility. The ratio (the proportion of the
population that shares a sanitation facility of an otherwise
adequate type among two or more households) derived
from the latest household survey/census is subtracted
from the trend estimates of improved sanitation facilities.
This results in the estimates for shared sanitation facilities.
The water supply and sanitation coverage estimates
presented in this report originate from data collected by
national statistics offices and other relevant institutions
through nationally representative household surveys
and national censuses. The survey data used were mainly
drawn from Demographic and Health Surveys, Multiple
Indicator Cluster Surveys, World Health Surveys, Living
Standards Measurement Surveys, Core Welfare Indicator
Questionnaires, Health and Nutrition Surveys, Household
Budget Surveys, Pan Arab Project for Family Health surveys
and Reproductive Health Surveys.
Regional averages
The JMP assembles, reviews and assesses these household
survey and census data. The JMP database currently
comprises data from over 600 surveys and censuses.
Differences in national coverage estimates
Population estimates
The population estimates in this report, including the
proportion of people living in urban and rural areas, are
those published by the United Nations Population Division
(2006 revision). These estimates may differ from national
estimates.
38
Methodology to derive MDG
progress estimates
Regional coverage estimates are calculated when the
available data cover at least 50 per cent of the population
in a region. For this report, insufficient data were available
to disaggregate each of the rungs of the sanitation
ladder for the developed regions, the Commonwealth of
Independent States and Oceania.
The MDG regional groupings (see map on the inside
back cover) have been used in all regional analyses and
tabulations.
Indicator definitions and population estimates used by
the JMP sometimes differ from those used by national
governments. Coverage estimates in this report may
therefore differ from national estimates.
Data comparability between JMP reports
For each report published by JMP, the country, regional
and global estimates on water and sanitation are revised.
For this reason, the data published in successive JMP

Millennium Development Goal 7 calls on countries to “halve, by 2015, the proportion of people without sustainable access to
safe drinking water and basic sanitation.” This report assesses the proportion of people with access to safe drinking water and
basic sanitation using the following MDG indicators:
- The proportion of the population that uses an improved drinking water source, urban and rural.
- The proportion of the population that uses an improved sanitation facility, urban and rural.
An improved drinking water source is defined as a
drinking water source or delivery point that, by nature of its
construction and design, is likely to protect the water source
from outside contamination, in particular from faecal matter.
The JMP uses the following classifications to differentiate
improved from unimproved drinking water sources.
An improved sanitation facility is defined as one that
hygienically separates human excreta from human contact.
The JMP uses the following classifications to differentiate
improved from unimproved sanitation facilities. However,
sanitation facilities are not considered improved when
shared with other households, or open for public use.

Since the last report, the JMP database has been updated with data from over 120 new surveys and censuses covering 84
countries:

Bottled water is considered to be improved only when the household uses water from an improved source for cooking and personal
hygiene; where this information is not available, bottled water is classified on a case-by- case basis.
Shared or public facilities are not considered improved.
Excreta are flushed into the street, yard or plot, open sewer, a ditch, a drainage way or other location.

The figures for Bangladesh have been adjusted for arsenic contamination levels based on the national surveys conducted and approved by the Government.
Countries with a negative growth rate, reflected in the columns titled ‘% of population that gained coverage (1990-2006) with respect to median population (Year 1998)’.
Figures have been estimated by JMP to ensure compatibility, thus they are not necessarily the official statistics of the concerned country, area or territory, which may use alternative rigorous methods.

Millennium Development Goals: regional groupings
In charting progress towards the MDGs,
the United Nations has classified the
world’s countries into three regions:
developed regions, developing regions
and the Commonwealth of Independent
States. The developing regions are further
divided into subregions shown on this map.
A complete list of countries included
in these subregions can be found at

July 2008
The world is not on track to
meet the MDG sanitation target
The world is on track to meet
the MDG drinking water target
Two and a half billion people, 38 per cent of the
world’s population, remain without improved
sanitation facilities, mostly in sub-Saharan Africa
and Southern Asia.
The number of people without an improved
drinking water source is now below one billion.
While 1.2 billion people still practise open
defecation, the riskiest sanitation practice of all,
it is decreasing.
At current rates, the MDG sanitation target will
be missed by over 700 million people.
Seven out of ten people without improved
sanitation live in rural areas.
More than half of the world’s households now
have piped water connections in or near their
homes.
Progress is slowest in sub-Saharan Africa,
home to a third of the global population using
unimproved drinking water sources.
Eight out of ten people without improved
sources of drinking water live in rural areas.
