number of people who are too old to work

annual number of infant deaths (children under the age of 1)

permanent move to a new location

a person forced to migrate to another country due to violence or can't return for fear of persecution based on race, religion, nationality, or membership in a social group

migration to a location

migration from a location

the difference between the number of immigrants and emigrants to and from a region

net migration from urban to rural areas in more developed countries

the tendency for population growth to continue beyond the time that replacement level fertility has been achieved because of a relatively high concentration of people in their childbearing years

permanent move from one region of a country to another

permanent movement within one region of a country

percent by which population grows annually

total of live births annually per 1,000 living people in an area

number of deaths 1,000 people

average number of children a woman will have throughout her childbearing years

wanting to increase CBR

a movement made by choice

a type of movement in which people do not choose to relocate, but do so under threat of violence

someone who has been forced to migrate for similar political reasons as a refugee but has not migrated across an international border

negative circumstances, events or conditions present in a migrant's home

destination's positive conditions and circumstances

the further away the location, the less likely a migrant is to travel there

the idea that migrants traveling long distances usually settle in urban areas

people move to communities where relatives or friends have previously migrated

when as mass of highly skilled/highly educated people move out of a country due to lack of economic opportunity

number of years needed to double a population (not always accurate)

the average number of years an individual can be expected to live based on social, economic and medical conditions

distinctive health threats in each stage of the demographic transition

a disease that occurs over a wide geographic area and affects a very high proportion of the population (ex. AIDs, ebola)

migration within a country

migration between countries

decrease in deaths from infectious diseases and increase in chronic disorders associated with aging (ex. cardiovascular illnesses, cancer)

cardiovascular/cancerous diseases linger but medicare advances increase

medical technology invented in Europe and North America diffused into developing countries; improved medical practices, eliminated traditional causes of death in developing countries, increased life expectancy

the total number of objects in an area

the number of people per unit area of arable land

the ratio of the number of farmers to the amount of arable land

the portion of Earth's surface occupied by permanent human settlement.

the scientific study of population characteristics.

short-term movements that recur regularly

all types of movements between locations

a change in the migration pattern in a society that results in industrialization, population growth and other social/economic changes that also produces the demographic transition

the idea that occupation of an area by different groups of people almost always leaves behind visible traces, some of which influence future human uses of the land

a process of change in a society's population from high crude birth and death rates and low rate of natural increase to a condition of low crude birth and death rates, low rate of natural increase, and higher total population
