AP Human Geography Unit 2

when the amount of people exceed the capacity of the environment to properly support life

europe, east asia, south asia, southeast asia

land that is permanently populated by human society

total number of people divided by total land area

total number of people supported by arable land

amount of farmers to the amount of arable land

hot, cold, dry, high, wet

rivers, oceans, fertile soil

the percentage by which a population grows per year

developing countries

total number of births per year for every 1000 people

total number of deaths per year for every 1000 people

the mount of people that can be supported by the evironment without damaging it

a diagram that shows how a country's population changes over time

high cbr and cdr, low nir

lack sanitation, medicine, contraceptives.
agriculture based society (subsistence ag)

high cbr, decreasing cdr, increasing nir. (population boom)

time period when land went from communally owned to privately owned

countries began to transition to stage 2 of dtm

increase knowledge in medicine, improve agricultural production, increase food surplus, movement to rural to urban,

decreasing cbr, decreasing cdr, increasing nir (becomes more modern)

more ppl live in cities so less need for large families, medical advancements, higher life expectancy, gender roles change,

low cbr, low cdr, flat nir

more economic activities for all citizens, more education for women, more jobs in tertiary sector, cost of living increases cus economy

cbr + cdr are same so nir is basically 0

policies created to help increase birth rates

policies created to help decrease birth rates

negative nir

describes the causes of death in each stage of the DTM

parasitic/infectious diseases, animal attacks, pandemics, epidemics, food shortages, dirty water. (bubonic plague)

spreads through a region or community

spreads through multiple regions, countries

disease that stays in a particular area and does not spread through the whole region/community

less deaths and receding pandemics, increased food production, sanitation, standard of living, industrial revolution/medical revolution,

degenerative diseases, heart attacks, cancer,

fighting degenerative diseases, medical advancements delay degenerative diseases, increases society life expectancy, improved diet + lifestyle choices, may also lead to obesity

reemergence of infectious diseases, evolution of diseases, increased poverty + urbanization, globalization,

stage 4

stage 3

stage 2

stage 1

stage 5

deaths due to pregnancy per 100,000 live births

number of people who are too young or too old to work

number of deaths of infants under 1 year per 1000 births

male births/female births * 100

• most migration happens for economic reasons and is done by young adults

• migrants often travel short distances and will travel in step migration

• migrants are more likely to move from rural to urban area

• women are more likely to move internally in a country

population grows exponentially, food grows arithmetically, population exceeds carrying capacity which would lead to famine, war, spread of disease, society destruction

populations did not continue to grow exponentially (more logistically), didnt account for advancements in agriculture/food production (counters the fact that food production is arithmetic)

countries in stage 2 of dtm do have a population growth which resembles J-curve,

permanent move within the same country

movement from one region of a country to another

migration within same region of a country

forced to migrate to another country to avoid effects of armed conflict and can’t return due to fear of persecution

forced to migrate due to similar regions as a refugee but doesnt cross an international border

someone who has migrated to another country in hopes of being recognized as a refugee

an environmental or political feature that hinders migration

people who enter the US without proper documentation

large scale emigration of talented people

the migration of people to a specific location because relatives/people of same nationality migrated there

a foreign worker who has been temporarily allowed to work in a host country

the temporary movement of a migrant worker between home and host countries to seek employment

negative situations/events that hinder migration and end up preventing migrants from reaching their final destination (no money/denied entry)

positive situations/events that hinder migration and end up preventing migrants from reaching their final destination

migrant leaves their home country to go somewhere else but still remains connected

migration that is cyclical and revolves around the seasonal movement of livestock
