Key figures

What the numbers say

In 2023, Africa Western and Central's vitamin A supplementation coverage rate (% of children ages 6-59 months) rose 13.02 percentage points on 2022 (from 67.58% to 80.6%).

This year's change was 0.5 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 49.54 percentage points in 2009 and the biggest yearly fall was 41.73 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 2014 to 2023 there is no clear straight-line trend: a straight line explains 2% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.
