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.
1,450 million means 145 crore people.
A large, growing population means a large workforce and consumer market.
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.
