Lower middle income: Tuberculosis case detection rate (%, all forms)

Key figures

What the numbers say

In 2024, Lower middle income's tuberculosis case detection rate (%, all forms) rose 3 percentage points on 2023 (from 77% to 80%).

Across the 23 yearly changes before that (2001 to 2023), the average change was +2.04 percentage points and a typical year strayed about 4.49 percentage points from that (the standard deviation). This year's change was 0.2 standard deviations above 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 9 percentage points in 2022 and the biggest yearly fall was 14 percentage points in 2020. 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 2.88 percentage points a year. A straight line explains 74% of the movement over 10 observed years.

A straight-line projection, tested first

Extending that straight line gives about 84.6% 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 7.98%, against 14.67% 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

Tuberculosis case detection rate (all forms) is the number of new and relapse tuberculosis cases notified to WHO in a given year, divided by WHO's estimate of the number of incident tuberculosis cases for the same year, expressed as a percentage. Estimates for all years are recalculated as new information becomes available and techniques are refined, so they may differ from those published previously.

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