What are the population characteristics?

Demography is the study of a population, the total number of people or organisms in a given area. Understanding how population characteristics such as size, spatial distribution, age structure, or the birth and death rates change over time can help scientists or governments make decisions.

Why it is important to identify the number of participants?

The more people that participate, the better the study is. Having a large number of participants reduces the risk of accidently having extreme, or biased, groups – such as having all adults or all children in a study that should have equal numbers of adults and children.

How do you determine the number of participants in a study?

All you have to do is take the number of respondents you need, divide by your expected response rate, and multiple by 100.

How is population analysis used in village planning?

Planners also study the present and future composition of the population and its spatial distribution to identify the best locations to provide services to meet local needs. Planners also examine population characteristics to determine the feasibility for new programs. A village may ask the government for a new school.

Why are population planners concerned about population change?

Planners are also concerned about the impact of new plans on population change.
