Why it matters

Annual and multi-year figures move slowly. A step this size is compared with how far the same series usually moves from one period to the next, so an ordinary year does not read as news.

For infant mortality rate, lower is better. This movement is therefore assessed as an improvement.

Historical context

Typical year-to-year movement over the previous 6 steps: 2.
