Population D&D
This measures the number of people living per unit area.
What is population density?
Births minus deaths equals this.
What is natural increase?
A broad base on a population pyramid usually indicates this.
What is a high birth rate?
This ratio compares dependents to working-age people.
What is the dependency ratio?
Policies encouraging larger families are known as these.
What are pro-natalist policies?
Two countries have identical population densities, but one has most people in a few cities. This population characteristic differs.
What is population distribution?
Movement of people into a country is called this.
What is immigration?
A narrow base on a population pyramid usually indicates this.
What is a low birth rate?
Children and elderly people are generally classified as these.
What are dependents?
Policies designed to reduce birth rates are called these.
What are anti-natalist policies?
A country has 80 million people and 400,000 km² of land. This is its population density.
What is 200 people per km²?
A country's death rate falls while birth rates stay the same. This happens to natural increase.
What is an increase in population growth?
A large bulge of males aged 20-45 often suggests this process.
What is labor migration?
A rising dependency ratio means each worker must support this.
What is a larger dependent population?
Increased access to contraception is commonly associated with this type of policy.
What is an anti-natalist policy?
Fertile soil, access to water, and mineral deposits are examples of these factors that influence where people settle.
What are economic factors?
Birth rate = 15/1000, Death rate = 10/1000. This is the natural increase.
What is +5 per 1,000?
A country with low birth rates and high life expectancy will likely have this type of population pyramid.
What is an ageing population structure?
A country has 20 million dependents and 40 million working-age adults. This is its dependency ratio.
What is 50 dependents per 100 workers?
A government offers tax incentives, paid parental leave, and childcare subsidies to achieve this demographic goal.
What is increasing the birth rate?
A country's density remains unchanged for 30 years, but its urban population rises from 40% to 85%. This demographic characteristic changed.
What is population distribution?
Birth rate = 16/1000, Death rate = 11/1000, Immigration = 2/1000, Emigration = 8/1000. This is the overall population change.
What is -1 per 1,000?
A pyramid showing few children, many elderly adults, and a shrinking workforce suggests this demographic challenge.
What is population ageing (or workforce decline)?
A country has 24 million people aged 0-14, 8 million aged 65+, and 48 million aged 15-64. This is the dependency ratio.
What is 66.7 dependents per 100 workers?
A country successfully lowers fertility rates for decades and later raises retirement ages and encourages larger families because of this demographic problem.
What is population ageing and workforce decline?
