ap human geo unit 2

1. Earth has a really large population right now

2. Earth's population is concentrated in developing countries

3. recently population was increasing the fastest its ever had

number of people exceeds capacity of the environment to support life (at decent standard of living)

important data source for population like polls on population / housing from the government

1. nonparticipation: homeless people and immigrants don't have access or won't take it out of fear of being kicked out of US

2. sampling: limit the amount of information you take so it's reflective on the entire population (1 is more accurate in housing vs 2 that's more accurate for people that weren't included the first time)

East Asia, South Asia, Europe, and Southeast Asia

area of Earth's surface occupied by permanent human settlement

1. too dry: can't farm and limited animals

2. wetlands: rain and heat make it hard to farm

3. cold lands: glaciers make it hard to farm and support animal life

4. mountains: high up it's snowy and hard to farm

total number of objects in a certain area (explains "where" comparing conditions in different countries) high density ex: Asia, Europe, Central America low density ex: North America, South America, South Pacific

number of people supported by a unit of arable land (gives more data: understanding capacity of land to yield enough food for people's needs and shows relation between size of population vs available resources) high density ex: Asia, Sub-Saharan Africa, South America low density ex: North America, Europe, South Pacific

ratio of number of farmers to amount of arable land (helps understand economic differences) high density ex: Asia, Sub-Saharan Africa low density ex: North America, Europe, South Pacific

% at which population grows in a year (doesn't include migration)

number of years needed to double the population (if it increased at constant rate)

average number of years a person can be expected to live

total number of births in a year per 1000

total number of deaths in a year per 1000

scientific study for population characteristics

number of predicted births in soicety

process of change in society's population (stage _ to stage _)

improving manufacturing (stage 1 to stage 2)

medical improvements (stage 1 to stage 2)

CBR is lower than CDR and NIR is 0 / negative

the branch of medical science dealing with the distribution and control of disease

distinctive health traits in each stage of the demographic transition stage 1: pestilence and famine stage 2: receding pandemics stage 3:degenerative diseases stage 4: delayed degenerative diseases

disease occurring globally effecting lots of people

Earth's resources can't support a growing population

education, health care, and contraceptives

reason to move away from current location

reason to move to a new location

a migrate that has been forcibly migrated (to new country) to avoid a potential death

forced to migrate (like refugee) but doesn't cross international border

migrated to another county in hope of being recognized as a refugee

across national borders (ex: US to Canada / Ireland to Japan)

move to different regions within same country (ex: California to Illinois / New York to Texas)

movement to smaller regions within a larger region (ex: rural to urban / urban to suburbs / LaGrange to Chicago)

use of power or authority causes involuntary movement not based on choice, when people must move for survival or are displaced by natural or environmental disasters, chemical or nuclear disasters, famine or war, forced migrations include slavery and events that produce refugees, IDPs, and asylum seekers

after a person considers options and choices, makes the decision to migrate (transnational, transhumance, interregional/intraregional, chain, step (stopping along the way to get to final destination), guest worker, and rural to urban migration)

begins at a home base and returns to the same spot (ex: people in Northern North American places travel to the South for winter / people go to college, then home for the holidays, then back to college, then home for the summer…etc.)

person does not necessarily return to the same place and sometimes takes place at irregular intervals (ex: military)

when people move according seasonal availability of land and food (ex: ranchers / livestock from highlands to lowlands)

when deciding where to go, migrants consider where friends and family have gone and been successful

fill a need for labor and then return to their home country

protection granted by a nation to someone who has left their native country as a political refugee

immigrants tend to travel to where people from similar decent have settled

an environmental / cultural feature of the landscape that hinders migration (usually negative)

an opportunity that changes migration plans (usually positive)

-most migrants travel short distances -rural people are more likely to migrate than urban people -long distance migrants tend to go to cities -men tend to be more internationally migratory and women tend to migrate internally -every migration flow generates a return or counter migration (for every flow there's a inflow) -most migrants go "step" by "step" and not from one extreme to another -young, single adults are more migratory than older adults of those with children -most people migrate for economic reasons

area subject to flooding during certain numbers of the years

the gradual transformation of habitable land into desert; is usually caused by climate change or by destructive use of the land

payment of money sent back home to a person's family while they are away making money

limit or number of immigrants allowed into a country

large scale emigration of skilled workers

immigrants that enter a country without proper documentation

process of people moving from rural to urban areas

process of people moving from urban to suburban areas
