fertility
the number of live births per 1000 people in a population in a given year
crude birthrate
the incidence of death in a population

population composition
the number of males for every hundred females in a given population
sex ratio
a graphic representation of the distribution of a population by sex and age
population pyramid
- power of population is infinitely greater than the power of the earth to produce subsistence [food] for man
- population growth inevitably surpasses the food supply, and the lack of food ultimately ends population growth and perhaps eliminates the existing population
malthusian perspective
overpopulation occurs because capitalists desire to have a surplus of workers in order to suppress wages and force workers concerned about losing their livelihoods to be more productive
marxist perspective
the point at which no population increase occurs from year to year
zero population growth
the process by which some societies have moved from high birth and death rates to relatively low birth and death rates as a result of technological development
demographic transition
