Slovak Republic: People using safely managed drinking water services (% of population)

Key figures

What the numbers say

In 2024, Slovak Republic's people using safely managed drinking water services (% of population) rose 0.06 percentage points on 2023 (from 99.51% to 99.57%).

Across the 23 yearly changes before that (2001 to 2023), the average change was +0.32 percentage points and a typical year strayed about 0.29 percentage points from that (the standard deviation). This year's change was 0.9 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 0.65 percentage points in 2011 and the biggest yearly fall was 0 percentage points in 2001. 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 0.06 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 99.74% 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 0.05%, against 0.12% 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 drinking water from an improved source that is accessible on premises, available when needed and free from fecal and priority chemical contamination. Improved water sources include piped water, boreholes or tubewells, protected dug wells, protected springs, and packaged or delivered water.

Limitations: In order to meet the criteria for a safely managed drinking water service, an improved water source should meet three criteria: it should be accessible on the premises (accessibility), water should be available when needed (availability), and the water supplied should be free from contamination (quality). Many countries lack data on one or more elements of safely managed drinking water. The WHO/UNICEF Joint Monitoring Programme for Water Supply, Sanitation and Hygiene (JMP) provide national estimates only when data are available on drinking water quality and at least one of the other criteria (accessibility and availability).

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