Topic 8.1: Human Populations Questions

The urban population of Veска is growing at 3.5% per year. Calculate the number of years it would take for the urban population to double in size.

Define the term crude birth rate.

Distinguish between the demographic terms natural increase and net migration.

Outline two factors that could cause the crude death rate in a low-income country to fall over time.

An age-structure diagram for the country of Eldoria has a wide base, a steadily narrowing middle and a small elderly section, with the base only slightly wider than the cohorts above it. Using these features, identify which stage of the demographic transition model (DTM) the country is currently in.

Outline two implications of an ageing population for a country in the later stages of the demographic transition model.

Explain how the rate of natural increase determines whether a population grows, stays stable, or declines.

The table shows demographic data for the city of Port Helia. Calculate the rate of natural increase of the population, expressed as a percentage.

Explain how the educational and economic status of women acts as a factor affecting population change.

The data table compares two countries at different stages of the demographic transition model. State which country, P or Q, is at the earlier stage of the demographic transition, and justify your choice using the data.

Outline how demographic tools can be used to study a human population.

Outline the four factors that cause population size to change.

Outline four factors that explain why the carrying capacity for human populations differs between countries.

Outline four difficulties in determining the carrying capacity of the human population.

Outline two factors that enable a human population to increase its local carrying capacity.

Evaluate the usefulness of the demographic transition model (DTM) for predicting population change in low-income countries today.

The table shows population data for the country of Solmira at the start and end of one year. Using the data, calculate the country's overall percentage population growth rate for the year, taking both natural increase and migration into account.
