Chapter 3-5 Flashcards
Any region between 30 degrees and 60 degrees north and south of the equator; where the majority of people live
midlatitude
a spike in the birth rate, especially after a period of conflict/ war or times of economic abundance
baby boom
the total number of people an area can support without damaging the environment
carrying capacity
the comparison between the potential workforce and the dependent population of a given population
dependency ratio
boundary adjustments made as a result of population growth or decline
redistricting
the total population divided by the total land area
population density
more people than a given land area can support; dependent upon distribution and density
overpopulation
when the people born during a baby boom reach childbearing years and begin to have children
echo
the pattern of human settlement; the spread of people across the earth
population distribution
a graph that presents the age-sex composition of a given population
population pyramid
suitable for agriculture (growing)
arable
the total population divided by the total area of arable land
physiological population density
a decline in the birth rate after a baby boom
baby bust
the hierarchical division of people into groups based on economic status, power, ethnicity, etc.
social stratification
age groups on a population pyramid
cohorts
the measure of the average population per square mile in a given area
arithmetic population density
the group expected to make up the labor force of a given population; ages 15-64
potential workforce
the group that relies on the labor force because they are too young or old to work; ages 0-14 and 65+
dependent population
the total number of farmers divided by the total are of arable land
agricultural population density
the slow down of the birth rate in a given population
birth deficit
the more people there are, the more hand there are to work, rather than just more mouths to feed
Boserup theory
the percentage at which a country’s population is growing or declining without the impact of migration
rate of natural increase
the stages of population growth as contextualized by a country’s transition from an agrarian to an industrial society
demographic transition model
the arithmetic growth of food production and the exponential growth of population leads to food scarcity and overpopulation
Malthusian Theory
