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.
A demographer studies shifts in the characteristics of populations. They study birth rates, death rates, and the age of the population.
If birth rates exceed death rates, the population increases proportionally. If death rates exceed birth rates, the population decreases.
Yes. Birth rates and death rates are factors of a population study. True. Easier for people to understand than yes.

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(:
Demographic transition
Characteristics of human populations include size, density, distribution, age structure, sex ratio, birth rates, death rates, and migration patterns. These characteristics can vary widely between different populations and have significant implications for social, economic, and environmental dynamics.
The tendency of a population to shift from high birth and death rates is called a demographic transition.
Stage 1: High birth and death rates, leading to a stable population. Stage 2: High birth rates and decreasing death rates, resulting in rapid population growth. Stage 3: Declining birth and death rates, leading to a slowing population growth. Stage 4: Low birth and death rates, resulting in a stable or declining population.
Birth rates and death rates
Demographers figure out population growth by comparing birth rates and death rates.
