representation of the change in a society's CBR, CDR, and NIR separated into five stages
stage 1 DTM

stage 2 DTM
high birth rates, declining death rates, high population growth (population boom), increasing life expectancy, most of Africa and LDCs
stage 3 DTM
declining birth rates, low death rates, decreasing population growth, NICs
stage 4 DTM

stage 5 DTM
birth rates lower than death rates, negative population growth, Japan/Germany/Greece
Malthusian Theory
states that population grows at an exponential rate while food supplies grow at a linear rate (population grows faster than food), so humans will eventually exceed the carrying capacity of the Earth
Malthusian Trap
point at which population exceeds food supply
graph showing exponential growth
replacement rate
rate at which enough children are born on average to replace the older generations, generally above 2%
Boserupian Theory
states that population will not exceed food supply due to human innovations and invention, contrast to Malthus
pro-natalist policy
government laws or programs that encourage higher birth rates
anti-natalist policy
government laws or programs that attempt to decrease birth rates
