Two neighboring countries. Two completely different trajectories in how fast families grow.

Gallup Pakistan Digital Analytics compared how family size actually builds up over a woman’s life in Pakistan and India, and the divergence is stark enough that it’s worth sitting with on its own.

By age 30-34, Pakistani women have already spread into a pattern where “4 or more children” is the single largest group, close to half of all women that age.

In India, that same milestone, the point where large families become the norm, doesn’t arrive until a full decade later, at age 40-44. And even then, it’s a smaller share than Pakistan had already reached ten years earlier.

Trace the full shape of it. In Pakistan, women move through one child, two children, three children in quick succession, and by their mid-30s a majority have already landed in large-family territory. In India, the same age groups spread out much more slowly. Two and three children remain the dominant categories well into the 40s.

Large families are the exception in India at an age where they’ve already become the norm in Pakistan.

A neighboring country, with a shared history and broadly similar starting conditions, has nonetheless built a completely different relationship between age and family size, a decade-plus apart on the same demographic milestone.

That kind of divergence only becomes visible when you look at the full shape of the data across ages, rather than a single national average.
