Demography dynamics

Using stats to study populations

Demography looks at changes in birth rates and death rates, which determine how fast populations grow or decline. Human population studies rely heavily on demography.

Demographers also analyse populations by age group, using population pyramids, like the ones in our infographic, to visualise this breakdown.
