Total Fertility Rate — methodology

What this metric measures

The average number of children born per woman over her lifetime (Total Fertility Rate).

Why it matters: Replacement rate is approximately 2.1. Falling birth rates lead to an ageing population, workforce strain, and greater dependency on migration to sustain the economy.
