Yemen, Rep.: People using safely managed sanitation services (% of population)

Key figures

What the numbers say

In 2024, Yemen, Rep.'s people using safely managed sanitation services (% of population) rose 0.66 percentage points on 2023 (from 42.46% to 43.12%).

Across the 23 yearly changes before that (2001 to 2023), the average change was +0.33 percentage points and a typical year strayed about 0.28 percentage points from that (the standard deviation). This year's change was 1.2 standard deviations above that average, so it was larger than a typical year, though not out of the range seen before.

On record, the biggest yearly rise was 0.72 percentage points in 2016. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2015 to 2024 the straight-line trend is upward, about 0.69 percentage points a year. A straight line explains 100% of the movement over 10 observed years.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.

A straight-line projection, tested first

Extending that straight line gives about 44.88% for 2027. We show this only because the same method, fitted on earlier years, predicted 2022 to 2024 better than "no change" would have: its average miss was 0.84%, against 1.35% for assuming no change. Treat it as a continuation of the recent pattern, not a forecast of events: it cannot see a recession, a policy change or a revision to the data.

What this measures

The percentage of people using improved sanitation facilities that are not shared with other households and where excreta are safely disposed of in situ or transported and treated offsite. Improved sanitation facilities include flush/pour flush to piped sewer systems, septic tanks or pit latrines: ventilated improved pit latrines, composting toilets or pit latrines with slabs.

Limitations: There are three main ways to meet the criteria for having a safely managed sanitation service (People should use improved sanitation facilities that are not shared with other households, and the excreta produced should either be: treated and disposed of in situ; stored temporarily and then emptied, transported and treated off-site, or transported through a sewer with wastewater and then treated off-site). Many countries lack information on either wastewater treatment or the management of on-site sanitation. A national estimate is produced if information is available for the dominant type of sanitation system. If no information is available, it is assumed that 50 percent is safely managed.

Regional and income-group figures are computed by the World Bank as a weighted average.
