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 sex ratio at birth, higher is better. This movement is therefore assessed as an improvement.
Historical context
Typical year-to-year movement over the previous 6 steps: 6. The two periods overlap, so most of the underlying data is shared.
