population statistics
Headcount and trends
Population statistics are numerical data about the inhabitants of a region—counts, birth rates, death rates, age distributions, migration patterns.
The term covers both raw census figures and derived measures like fertility rates or life expectancy.
Demographers use population statistics to track growth, predict future needs, and inform policy decisions about housing, healthcare, and infrastructure.
