1

Whats the birth rate?

Desire for economic security. Full time job and pursuit of career. Access to family planning and contraception. Better healthcare.

4

What lowers death rate?

Access to health care. Access to clean water. Improved living conditions. Agricultural production and secure food supply.

Whats natural change?

The difference between birth and death rate. If birth rate is higher than death rate then there will be natural increase.

6

Whats fertility rate?

The numbers of live births per 1000 women of reproductive age (15 - 45) per year.

7

Whats infant mortality rate?

The average number of children per 1000 born who die in their first year of life.

8

Whats longevity?

11

Whats a dependent population?
