AP HUG Unit 2 Reverse Flashcards
the study of population characteristics
demography
how people are spread out through an area
population distribution
factors that influence where and how many people live in an area. based on geographic/environmental strengths and weaknesses
physical factors influencing population
the portion of earth’s surface settled by humans
ecumene
factors that influence where and how many people live in an area that are based on human causes
human factors influencing population
where people are clustered
population concentration
where people are spread out across the globe
population distribution at a global scale
where people are spread out across a nation
population distribution at a national scale
where people are spread out across a local area
population distribution at a local scale
the amount of people over the amount of land in an area
population density
people per unit of land in an area
arithmetic density
people per unit of arable land in an area
physiological density
farmers per unit of arable land in an area
agricultural density
land that can be used for agriculture
arable land
impacts that are related to economic effects. in this context, impacts from density and distribution
economic implications
impacts related to politics. in this context, impacts from density and distribution
political implications
impacts related to social effects. in this context, impacts from density and distribution
social implications
impacts related to the environment. in this context, impacts from density and distribution
environmental implications
the amount of people or animals an area can sustain without significant damage
carrying capacity
having a population that exceeds the carrying capacity of an area
overpopulation
basic services used in the operation of a city
infrastructure, urban services
someone’s race, culture, or demographic
ethnicity
factors that show how old and what genders an area has
age-sex composition
percentage of males to females
sex ratio
different age groups on a population pyramid
cohort
an explosion in the number of births
baby boom
slowing of population growth after a baby boom
baby bust
a spike or drop in a population as a result of an earlier spike or drop
echo
ratio of working are people to the dependent population
dependency ratio
people between age 15 and 65
potential workforce
people above age 65 or below 15
dependent population
survey that gathers data about population and demographics
census
the tendency for growing population to continue growing after a fertility decline because of their young age distribution
demographic momentum
rate of growth for a population excluding any outside factors. just CBR/CDR.
RNI, rate of natural increase
amount of time it takes for a population to double
population doubling time
people are dying at the same rate that they are being born
ZPG, zero population growth
total births per 1,000 people
CBR, crude birth rate
total deaths per 1,000 people
CDR, crude death rate
model that predicts and explains population growth
DTM, demographic transition model
what stage of the DTM is characterized by high fluctuating CBR and CDR
stage one
what stage of the DTM is characterized by a declining CDR and a fairly stable CBR
stage two
what stage of the DTM is characterized by a decline in the CDR’s rate of decline and a declining CBR
stage three
what stage of the DTM is characterized by a low fluctuating CBR and CDR
stage four
what stage of the DTM is characterized by many different ideas: a stable CBR and CDR, or CDR surpassing CBR, etc.
stage 5
