Brunei Darussalam: UHC service coverage sub-index on infectious diseases

Key figures

What the numbers say

In 2023, Brunei Darussalam's UHC service coverage sub-index on infectious diseases rose 1 on 2022 (from 99 to 100).

Across the 22 yearly changes before that (2001 to 2022), the average change was +1.18 and a typical year strayed about 0.39 from that (the standard deviation). This year's change was 0.5 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 2 in 2004. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2014 to 2023 the straight-line trend is upward, about 1.15 a year. A straight line explains 99% 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 103.81 for 2026. We show this only because the same method, fitted on earlier years, predicted 2021 to 2023 better than "no change" would have: its average miss was 0.53, against 2 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

UHC service coverage sub-index on infectious diseases is based on four tracer indicators: (i) Tuberculosis, (ii) HIV/AIDS (iii) Malaria (iv) Water, sanitation and hygiene. It is presented on a scale of 0 to 100 index points and is one of the four sub-indexes underlying the overall UHC service coverage index.

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