Final answer:
The size and growth rate of a population are key indicators of population dynamics and are studied in the field of demography. Factors such as birth rates, death rates, immigration, and emigration impact the population growth rate.
Step-by-step explanation:
The size and growth rate of a population are often measures of population dynamics in the field of demography. Population size refers to the total number of individuals in a population, while population growth rate indicates how quickly the population is increasing or decreasing over time.
Factors such as birth rates, death rates, immigration, and emigration impact the population growth rate. These factors determine whether a population is growing rapidly, slowly, or declining.
For example, high birth rates and immigration contribute to population growth, while high death rates and emigration can lead to population decline.
In summary, the size and growth rate of a population are key indicators of population dynamics, which are studied in the field of demography.
