Birth rates and death rates
Demographers figure out population growth by comparing birth rates and death rates.

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.
rapid population growth
Birth rates, death rates, and population growth over time.
Birth rates and death rates are used to calculate the rate at which a population is growing. When the birth rate exceeds the death rate, the population is increasing. Conversely, if the death rate is higher than the birth rate, the population is decreasing. The difference between the birth rate and death rate over a period of time is known as the natural increase rate.
If birth rates exceed death rates, the population increases proportionally. If death rates exceed birth rates, the population decreases.
natrual increas?
Yes, in the first stage of the demographic transition, both birth rates and death rates are high, resulting in a stable population size. This is typically seen in pre-industrial societies where high birth rates compensate for high death rates, leading to minimal population growth.
Birth rates rise as death rates fall?
The United States and the United Kingdom are both in stages of demographic transition. For both countries, an influx of immigrants have changed the culture.
