-
Pandemic
-
Epidemic
-
Outbreak
-

Which of the following is NOT a component of population change?
-
Births
-
Deaths
-
Migration
-
Aging
D
Correct answer
Explanation
Aging is not a component of population change, but rather a result of changes in the birth and death rates.
Which of the following factors is NOT taken into account in the cohort-component method?
-
Age structure of the population
-
Sex structure of the population
-
Fertility rates
-
Mortality rates
Correct answer
Explanation
Migration rates are not taken into account in the cohort-component method because they are difficult to predict.
What is the most important factor to consider when making population projections?
-
The age structure of the population
-
The sex structure of the population
-
The fertility rate
-
The mortality rate
A
Correct answer
Explanation
The age structure of the population is the most important factor to consider when making population projections because it determines the future size and composition of the population.
Which of the following is NOT a method for forecasting migration?
-
Gravity model
-
Push-pull model
-
Economic model
-
Demographic accounting method
D
Correct answer
Explanation
The demographic accounting method is not a method for forecasting migration. It is a method for estimating migration based on data on population change and natural increase.
Which of the following is NOT a type of population projection?
-
High projection
-
Low projection
-
Medium projection
-
Constant projection
D
Correct answer
Explanation
A constant projection is not a type of population projection because it does not take into account any changes in fertility, mortality, or migration.
Which of the following is NOT a method for forecasting fertility?
-
Cohort analysis
-
Period analysis
-
Trend analysis
-
Expert opinion
D
Correct answer
Explanation
Expert opinion is not a method for forecasting fertility. It is a method for gathering information about future trends in fertility.
Which of the following is NOT a type of population forecast?
-
Short-term forecast
-
Medium-term forecast
-
Long-term forecast
-
Rolling forecast
D
Correct answer
Explanation
A rolling forecast is not a type of population forecast. It is a method for updating a population forecast on a regular basis.
What is the most important factor to consider when making population forecasts?
-
The age structure of the population
-
The sex structure of the population
-
The fertility rate
-
The mortality rate
A
Correct answer
Explanation
The age structure of the population is the most important factor to consider when making population forecasts because it determines the future size and composition of the population.
