The birth rate of a population is expressed as a

• decimal.

• ratio.

• fraction.

• logarithmic equation.

• percentage.

If the growth rate r of a population is positive and remains constant, the number of people added to the population

• remains constant.

• fluctuates randomly.

• decreases each year.

• reaches carrying capacity.

• increases each year.

The most critical factor in controlling human population growth is

• controlling reproductive lifespan.

• decreasing the age of first birth.

• decreasing the average number of births per woman.

• decreasing infant death.

• increasing overall wellness for the human race.

The total fertility rate (TFR) is an estimate of

• the number of children that will survive to adulthood.

• the number of years a typical infant will live.

• the number of children each woman in a population will have.

• the number of births per 1000 people per year.

• the percentage of women in a population that are able to have children.
