agricultural period

age structure

- number of males and females of each age in a population; - the distribution of the population based on age categories.

industrial period

- third period of human population growth. This period is from 1,000 years ago to current day and is characterized by advances in technology.

Demographers have identified three distinct periods of human population growth that help explain the history of how our population has changed;

During the _____, it took the human population around 1,000 years for it to double in size.

agricultural period {Explanation - Unlike during the pre-agricultural period, when it took tens of thousands of years for the human population to double, during the agricultural period, it only took around 1,000 years for it to double in size}

highly developed country

an industrialized country that is characterized by a low fertility rate, low infant mortality rate, and high per capita income; (eg the US)

replacement-level fertility

the total fertility rate required to offset the average number of deaths in a population in order to maintain the current population size

The _____ is the average number of offspring born to a woman in a population during her reproductive years.
