because birth rates and death rates relate to population. the Birth Rate shows how much a population is increasing, and death rates show how much a population is decreasing. when you average the two out, it will give you the population(:
the answer is by comparing birthrates and death rates
Birth rates and death rates
Demographers figure out population growth by comparing birth rates and death rates.
demographic transition
Demographers study characteristics such as population size, age structure, birth and death rates, migration patterns, fertility rates, and population density. These characteristics help demographers understand population dynamics and trends over time.
Population decreases
For the past century the birthrates in human culture have far out numbered the death rates which is why our world population has been steadily growing. People are living longer than they did in our past.
Demographers study populations and their characteristics, such as birth rates, death rates, and migration trends. They analyze data to understand population dynamics, forecast future trends, and provide insights for social and economic policy-making. Demographers also research topics like aging, fertility, and urbanization.
The ice in the box
Probably, but birthrates, too.
Birthrates , death rates, women and male intercourse
When death rates lowered but birthrates stayed high, the population skyrocketed.
