Match each population concept or growth index on the left with its corresponding demographic definition or structural relationship on the right.
- Crude Birth Rate (CBR)The total number of live births recorded in a year per 1,000 mid-year population.
- Rate of Natural Increase (RNI)The net percentage annual population change resulting exclusively from the surplus of live births over deaths.
- Total Dependency RatioThe proportion of non-working population (ages 0–14 and 65+) relative to the economically productive cohort (ages 15–64).
- Population MomentumContinued growth of a population despite fertility rate decline, caused by a large proportion of youthful cohorts reaching childbearing age.
Answer
The correct pairings match Crude Birth Rate with live births per 1,000 mid-year population; Rate of Natural Increase with net annual percentage growth from birth surplus over deaths; Total Dependency Ratio with the ratio of non-working dependent age groups to the working-age group; and Population Momentum with sustained population growth driven by a high proportion of young people entering reproductive age.
Each demographic concept is matched strictly with its standard analytical definition used in population geography.
