What is the most serious problem caused by population growth?

Back

The most serious problem caused by population growth is the increasing demand for resources, which can lead to shortages and environmental degradation.

What does a slowly growing population pyramid indicate?

Back

A slowly growing population pyramid has a relatively even distribution across age groups, with a slight increase in the younger age cohorts.

Front

Which population pyramid reflects a less developed country?

Back

Front

What factors can influence population growth?

Back

Factors influencing population growth include birth rates, death rates, immigration, and emigration.

Population pyramids can be used in urban planning to estimate future housing, education, and healthcare needs based on the age structure of the population.

Front

What does a population pyramid with a bulge in the middle indicate?

Back

A bulge in the middle of a population pyramid indicates a large working-age population, which can suggest economic growth potential.

Front

What are the implications of an aging population?

Back

An aging population can lead to increased healthcare costs, a shrinking workforce, and greater demand for retirement services.
