demographic variables encompass the values, beliefs, and behaviors shared by a group of people.
<h3>What is
demographic variables?</h3>
A demographic variable is one that researchers collect in order to define the type and distribution of the sample when using inferential statistics. These are variables in applied statistics and research such as age, gender, ethnicity, socioeconomic measures, and group membership.
Age, gender, ethnicity, fertility rates, and other factors are examples. The study of human populations is known as demography. If your research is concerned with how attributes differ between people or groups of persons, you will be seeking for demographic statistics.
Demographic factors can have a significant impact on income distribution. This article examines the influence of three demographic variables on inequality: (a) age structure; (b) marriage and household composition; and (c) differential fertility by income.

Explanation:
Answer:
Reduce the rate of evolution
Explanation:
Sexual reproduction is the mode at which living organisms produce variation in species. This is important for phenotypic plasticity, adaptation, evolution and preservation of a species. The crux of sexual reproduction is to allow the exchange of genetic material between two genetically diverse individuals to produce offspring that are genetically diverse from both parents and the individuals in its clutch. Whenever sexual recombination occurs between hyphae of the same mating type there is no variation in genetic information and therefore no opportunity for variation. Unless there are external factors that influences gene sequences there will be few to no chances for variation. This reduces the rate of evolution considerable and exposes the specie to deletion if they encounter a disease or environmental condition they cannot overcome.
Answer:
C. low level of education
Explanation:
Low level of education is generally determined by the way the education system is designed/implemented. Population wouldn't give direct impact to this. Here are how over-population can cause problems on the other options:
- Pollution
Every individuals produce a certain amount of waste from the consumption of their product. The more population exist in a country, the more waste will be created.
- Disease
Over-population often forced many people to live in a cramped/unsanitary areas. This will increase the rate of disease in that area.
- Employment
The increase in potential labor force in an overly populated area often rise faster compared to the increase in job opportunities. This will cause a high amount of unemployment.
