The way people are spread out over an area

• population density

• population distribution

• urbanization

• "push-pull" theory

The movement of people to cities and the growth of cities

• urbanization

• death rate

• Green Revolution

• rural area

The average number of years a person is expected to live

• death rate

• urbanization

• life expectancy

• population density

A place where few people live

• urbanization

• urban area

• Green Revolution

• rural area

The average number of people who live in a square mile or kilometer of land.

• population density

• rural area

• urban area

• population distribution

One reason more than 81% of the Earth's population lives in Asia, Europe, and North America

• These continents have large deserts.

• These continents have sources of fresh water.

• These continents have little rainfall.

• These continents are covered by rain forests.

Population distribution is uneven because people want to live in areas that have

• rich resources

• dry grasslands

• extreme climates

• thick rain forests

A country that has high population density has

• few urban areas.

• some crowded areas.

• a lot of land per person.

• few people under 65 years old.

By comparing birthrates and death rates demographers figure out

• why people migrate.

• population growth.

• where people are likely to move.

• population density.

Due to an increase in food supply & better medical care, the world's population recently has

• rapidly increased.

• made educational gains.

• slowly decreased.

• remained the same.
