Is Pakistan’s top income quintile already below replacement fertility?

A quiet demographic shift may already be visible in national household data — even without separating urban and rural.

From Pakistan-wide 2024–25 household composition data, the top income quintile shows:

Average household size: 4.65
Average adults per household: 3.25
Average children per household: 1.40

That last number matters most.

If households contain roughly two adults of child-bearing age, but only 1.4 children, this implies fewer than two children per couple — i.e. at or near replacement fertility.
