Answer:
Demography
Step-by-step explanation:
Demography is the study of the population and how they are distributed in an area according to factors such as birth, death and migration.
In Demographics,women are mostly more than men in a given area. The Asia-America women are usually more than men and have a higher chance of marrying non-Asia men due to the demographics of a large population of American men.
The low population of Asia-American men and more American women who prefer their fellow citizens makes it difficult for the Asia- American men to marry.
