Poverty No Sanitation (% of population) in Africa

Poverty No Sanitation (% of population) in Africa measures the share of people living below the international poverty line who also lack access to basic sanitation facilities. As of the latest available year, this overlap remains high across much of Sub-Saharan Africa, where roughly two-thirds of the population lacks basic sanitation and a large share still lives on less than the international poverty line. Because the indicator combines income poverty with service deprivation, it offers a sharper picture of overlapping disadvantage than either measure alone, and 24Peaks hosts the latest series for every African economy.

What the indicator measures

The indicator captures the intersection of two deprivations at the household level: monetary poverty and the absence of basic sanitation. In practice, a person is counted when their household consumption or income falls below the international poverty line (currently $2.15 per day in 2017 PPP terms, set by the World Bank) and the household's sanitation facility does not meet the basic standard defined under the WHO/UNICEF Joint Monitoring Programme (JMP), which means no improved facility used exclusively by the household.

The underlying data come from two families of sources. Poverty estimates rely on nationally representative household surveys, typically Living Standards Measurement Studies (LSMS), income and expenditure surveys, or harmonized regional surveys. Sanitation data come from the same or comparable surveys plus censuses and JMP modelling. Because the two measures are not always collected in the same survey year, statistical agencies and international bodies interpolate or align years; the published value therefore refers to a specific survey reference year, not necessarily the current calendar year.

A key methodological nuance: the percentage is a headcount ratio, not a gap measure. It tells you how many people are doubly deprived, not how deep either deprivation is. A country can show a moderate combined rate while still having severe sanitation deficits in specific regions or among specific groups, and disaggregation matters.

Why it matters for investors and policymakers

Overlapping poverty and sanitation deficits have direct economic consequences. Poor sanitation is associated with diarrheal disease, child stunting, and reduced school attendance, all of which lower human capital accumulation and future productivity. When those burdens fall on the poorest households, they reinforce intergenerational poverty traps and hold back the growth of domestic consumer markets.

For investors, the indicator is a signal about structural risk and opportunity. High deprivation rates often coincide with weak infrastructure, limited fiscal space for public services, and dependence on external financing. At the same time, countries making progress on sanitation tend to show improving health outcomes, higher labor force participation, and more predictable operating environments for consumer-facing and infrastructure businesses.

The measure also tracks policy performance. Sustainable Development Goal 6 targets universal access to sanitation, and SDG 1 targets poverty elimination; this indicator sits at their intersection. Multilateral lenders including the World Bank and African Development Bank use such combined deprivation measures when allocating concessional finance and designing water and sanitation programs, so changes in the series can precede changes in a country's borrowing terms and project pipelines.

Recent trends across African regions

As of the latest available year, the combined poverty and no-sanitation rate remains highest in Sub-Saharan Africa, and within it, in Central and West Africa. In several Sahelian and Central African economies, the double deprivation rate is estimated at well above 40 percent of the population, reflecting both low incomes and very limited sanitation coverage in rural areas.

East Africa presents a mixed picture. Kenya, Tanzania, and Rwanda have recorded gradual declines in the combined rate, helped by sustained sanitation campaigns and, in some cases, faster income growth. Ethiopia has reduced income poverty in recent decades but rural sanitation coverage remains uneven across regions, so the overlap stays elevated.

North Africa and Southern Africa's middle-income economies generally show much lower combined rates. In North Africa, extreme income poverty is rare, so the intersection indicator is small even where sanitation coverage is not universal. In Southern Africa, countries such as Botswana and South Africa have relatively low income poverty headcounts at the international line, though inequality and informal urban settlements create localized sanitation deficits that national averages can mask.

The broader regional trend is slow improvement punctuated by setbacks. Population growth in Sub-Saharan Africa means the absolute number of people who are doubly deprived has fallen much more slowly than the percentage rate, and in some years it has risen even as the rate edged down. Country-level year-to-year movements should always be read with the survey reference year in mind.

Limitations to keep in mind

The indicator inherits the weaknesses of both component measures. Poverty estimates depend on survey design, recall periods, and price deflators, and different countries use different survey instruments, which limits strict cross-country comparability. Sanitation definitions changed when the JMP moved from "improved" to "basic" service standards, so older series may not be directly comparable with newer ones.

Timing is another issue. Household surveys are infrequent in many African countries, sometimes more than five years apart, so the published figure may describe conditions from several years ago. When a country updates its survey, the combined rate can shift noticeably for reasons of measurement as well as real change.

Finally, national averages hide distribution. A single percentage cannot show whether deprivation is concentrated among a particular ethnic group, region, or income decile. Investors and analysts should pair the headline rate with subnational data, urbanization rates, and water sector investment trends before drawing conclusions about a specific market.

FAQ

What does Poverty No Sanitation (% of population) actually count?

It counts people who are simultaneously below the international poverty line and living in a household without basic sanitation. Both conditions must hold for a person to be included. It is an overlap measure, not a simple sum of two separate deprivation rates.

Which African region has the highest combined rate?

Sub-Saharan Africa, and particularly Central and West Africa, shows the highest combined poverty and no-sanitation rates as of the latest available year. North Africa is far lower because extreme income poverty is rare there. Within Sub-Saharan Africa, rural areas consistently outpace urban areas on deprivation.

Why is the data often several years old?

The indicator depends on nationally representative household surveys, which most African statistical agencies conduct every three to five years or less often. International bodies interpolate between surveys, but the reference year can lag the present. Always check the survey year attached to a value on 24Peaks.

How is basic sanitation defined in this indicator?

It follows the WHO/UNICEF JMP standard: an improved facility such as a flush toilet, pit latrine with slab, or composting toilet that is not shared with other households. Shared or unimproved facilities, and open defecation, count as lacking basic sanitation. The definition is consistent across countries, though survey questions vary slightly.

Can the rate fall while the number of deprived people rises?

Yes. If sanitation coverage and incomes improve slowly while the population grows quickly, the percentage can decline even as the absolute number of doubly deprived people increases. This is a common pattern in high-fertility Sub-Saharan African countries. Analysts should track both the rate and the underlying population.
