North-west age refers to the estimated median age at which a population in a given north-west region reaches key life milestones, typically derived from census and survey data. It is not a universal biological threshold but a region-specific summary measure shaped by migration, fertility, and mortality patterns. Analysts use this metric to compare ageing and dependency trends between areas, informing resource planning and policy. This guide explains how north-west age is defined, measured, interpreted, and applied, with examples from countries and subnational regions where the concept is regularly reported.
