Question
What are the two numbers involved in expression of demographic concepts?
Solution
Demographic concepts are that of birth rate, death rate, infant mortality rate, fertility rate etc. These are expressed with two numbers. The one is the particular statistic enumerated for a specific geographical administrative unit (i.e. a state, country, district or other territorial unit). Another number provides a standard for comparison {i.e., total number or birth of death of people in a year divided by the total population of that area in thousands).
