• The birth rate equals the death rate.

• The birth rate is less than the death rate.

• The birth rate is greater than the death rate.

• The birth rate and the death rate both equal 0.

Demographic transition is change from high birthrates and high death rates to

• exponential growth.

• low birthrates and low death rates.

• low birthrates and high death rates.

• indefinite growth.

Using Figure 5–6, describe the type of growth Mexico is experiencing.

• Mexico is experiencing a rapid growth rate because there are more children than adults.

• Mexico is experiencing no growth because people are living longer.

• Mexico is experiencing slowed growth because there are fewer adults.

• Mexico is experiencing a rapid decline because there are more children than adults.

• Birth rate would be equal to the death rate.

• The death rate would increase.

• Immigration would increase.

In stage 3 of the demographic transition, birth rate starts to fall,

• so population growth starts to slow

• so population growth starts to speed up

In the context of the Birth and Death Model, what does a stable population imply?

• The birth rate is equal to the death rate.

• The birth rate is greater than the death rate.

• The birth rate is less than the death rate.

• The birth rate and death rate are both zero.

• Death rate is higher than birth rate.

• Birth rate and death rate are both increasing.
