What else can I help you with?
What do demographers compare to figure out population growth?
Birth rates and death rates
How do demographers figure out population growth.?
Demographers figure out population growth by comparing birth rates and death rates.
What is the factor that controls the growth of a population?
the fitest survive
What occur at each of the four stages of 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.
High birth rates and falling death rates would cause which demographic trend?
rapid population growth
The demographic transition model describes changes in?
Birth rates, death rates, and population growth over time.
How are birth rates and death rates used to measure population growth?
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.
How birth rates and death rates influence the size of a population?
If birth rates exceed death rates, the population increases proportionally. If death rates exceed birth rates, the population decreases.
The change in growth rate that results from the change in birth and death rates is known as?
natrual increas?
In the first stage of the demographic transition both birth rates and death rates are high?
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.
Why death rates tend to fall before birth rates?
Birth rates rise as death rates fall?
What are the Stages of demographic transition?
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.
