What the numbers say
In 2023, São Tomé and Principe's vitamin A supplementation coverage rate (% of children ages 6-59 months) rose 27 percentage points on 2022 (from 8% to 35%).
Across the 17 yearly changes before that (2004 to 2022), the average change was +1.29 percentage points and a typical year strayed about 30.84 percentage points from that (the standard deviation). This year's change was 0.8 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 76 percentage points in 2004 and the biggest yearly fall was 58 percentage points in 2022. 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 2023 there is no clear straight-line trend: a straight line explains less than 1% of the movement over 9 observed years, so the value is moving around more than it is heading anywhere.
