Final answer:
Demography is the study of the population and its characteristics, including age, income, gender, education, marital status, and type of dwelling. Six common demographic measures include birth rate, death rate, infant mortality rate, life expectancy, fertility rate, and population growth rate. The age-sex structure of a population is visualized through a population pyramid, which provides insights into the population's age distribution and potential social and economic implications.
Step-by-step explanation:
Demography is the study of the population and its characteristics. It focuses on various aspects of the population including age, income, gender, education, marital status, and type of dwelling. Six common demographic measures include birth rate, death rate, infant mortality rate, life expectancy, fertility rate, and population growth rate.
The age-sex structure of a population refers to the distribution of males and females across different age groups within the population. A population pyramid is a graphical representation of the age-sex structure of a population. It consists of two back-to-back bar graphs, with males on one side and females on the other. The width of the bars represents the size of each age group, and the shape of the pyramid indicates the population's growth or decline. Population pyramids provide valuable insights about a population. They can reveal information about the population's age distribution, gender imbalances, birth rates, death rates, population growth, and potential social and economic implications.
