Comoros: Low-birthweight babies (% of births)

Key figures

What the numbers say

In 2020, Comoros' low-birthweight babies (% of births) fell 0.15 percentage points on 2019 (from 23.17% to 23.03%).

Across the 19 yearly changes before that (2001 to 2019), the average change was −0.12 percentage points and a typical year strayed about 0.02 percentage points from that (the standard deviation). This year's change was 1.5 standard deviations below that average, so it was larger than a typical year, though not out of the range seen before.

On record, the biggest yearly fall was 0.15 percentage points in 2018. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2011 to 2020 the straight-line trend is downward, about 0.14 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 22.65% for 2023. We show this only because the same method, fitted on earlier years, predicted 2018 to 2020 better than "no change" would have: its average miss was 0.05%, against 0.3% 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.
