Section 1: Population

The way the population is spread out over an area

• Demography

• population

• population density

• population distribution

the science that studies population distribution and change

• Demography

• population

• population density

• population distribution

the average number of people per square mile or square kilometer

• Demography

• population

• population density

• population distribution

the number of deaths each year per 1,000 people

• death rate

• birthrate

• population distribution

• population density

total number of people in an area

• Demography

• population

• population density

• population distribution

the number of live births each year per 1,000 people

• population

• population density

• population distribution

• birthrate

To find the population density of a place, divide the number of people living there by the number of

• mountains

• rivers

• square miles or kilometers

• countries

Demographers are able to figure out population growth by comparing

• live expectancies.

• diseases.

• birthrates and death rates.

• the birthrate has decreased.

How have advances in medicine affected population?

• People live longer.

• More babies are born.

• The death rate has increased.

• The birthrate has decreased.

An example of how rapid population growth can affect the environment may include

• better jobs.

• an increase in trees.

• shrinking forests.

• cleaner waterways.
