Final answer:
The statement about the study of population features like birth rate, death rate, population size, and density being part of demography is true. Demography analyzes population changes over time, and uses life tables to summarize demographic characteristics.
Step-by-step explanation:
The study of a population's features and vital statistics, including birth rate, death rate, population size, and population density, is true. This field of study is known as demography, which is the statistical study of population changes over time. Important aspects like birth rates, death rates, and life expectancies are critical to understanding the dynamics of populations. Demographers utilize a variety of data, including vital statistics and censuses, to assess population characteristics. These characteristics, such as population size and density, can influence birth and death rates as well as the overall health and growth patterns of a population.
For example, a larger population size may lead to a higher birth rate due to more reproductive individuals. However, it might also lead to a higher death rate because of increased competition for resources. Factors like population density, sex ratio, and age structure also play a crucial role in the reproductive dynamics of a population. Tools such as life tables are commonly used by demographers to summarize these demographic characteristics.
