Understanding Population — a simple guide

What it measures

Total mid-year population.

How it is calculated

Total residents at mid-year, from censuses and official estimates.

Simple example

1,450 million means 145 crore people.

▲ When it is high or rising

A large, growing population means a large workforce and consumer market.

▼ When it is low or falling

A shrinking or ageing population can slow long-term growth.

Why it matters for the economy and markets

Population size and growth shape labour supply, consumption and long-term growth potential.

How to read it

Compare growth rates and age structure rather than size alone.
