Demographics usually measure population characteristics such as ethnicity and race. They typically focus on statistical factors that influence population growth or social composition, including population size, age structure, sex ratio, and ethnic groups. Height and weight are generally not standard demographic measures, nor are the number of resources or schools directly counted in demographic statistics but may be related to socioeconomic studies.
Key Population Characteristics Measured by Demographics
- Ethnicity and race: These are common demographic categories used to describe population composition.
- Age and sex: The age structure and sex ratio of a population are vital demographic parameters.
- Population size and density: Total number of individuals and how they are distributed geographically.
- Fertility and mortality rates: Birth and death rates help understand population growth.
Characteristics not typically measured directly by demographics:
- Number of resources
- Number of schools
- Physical attributes like height and weight (these may be measured in health or nutrition studies but not typical demographics)
Thus, among the options given, ethnicity and race are the main population characteristics usually measured by demographics.
