Demographic Transition Model | a sequence of demographic changes in which a country moves from high birth and death rates to low birth and death rates through time |
epidemiology | a branch of medicine that deals with incidence, distribution, and possible control of diseases and other factors relating to health |
Epidemiological Transition Model | a shift in the disease pattern of a population as mortality fell during the first stages of the demographic transition. Acute infectious diseases were reduced, whereas chronic, degenerative diseases increased. It also meant a gradual upward shirt in the age distribution of deaths. |
Crude Birth Rate (CBR) | the number of births per 1,000 individuals per year |
Crude Death Rate (CDR) | the number of deaths per 1,000 individuals per year |
demography | Scientific study of human populations |
dependency ratio | the number of people under age 15 and over 64 compared to the number of people active in the labor force |
ecumene | the portion of the earth's surface occupied by permanent human settlement |
infant mortality rate (IMR) | the total number of deaths in a year among infants under 1 year old for every 1,000 live births in a society |
life expectancy | a figure indicating how long, on average, a person may be expected to live |
Maternal Mortality Rate | Number of deaths per thousand of women giving birth |
epidemic | a widespread outbreak of an infectious disease |
pandemic | disease that occurs over a wide geographic area and affects a very high proportion of the population |
zero population growth | A decline of the total fertility rate to the point where the natural increase rate equals zero. |
total fertility rate (TFR) | The average number of children a woman will have throughout her childbearing years. |
Malthusian Theory | focuses on how the exponential growth of a population can outpace growth of the food supply and lead to social degradation and disorder |
Neo-Malthusian Theory | Revisions of Malthusian theory about food production and population growth that include more information, such as taking into account the effects of technology. |
Boserup Theory | Population growth stimulates intensification in agricultural development- opposite of Malthus theory. |
immigration policy | government rules governing how individuals can enter a country and how long they are allowed to stay |
pronatalist | a government policy that encourages or forces childbearing, and outlaws or limits access to contraception |
antinatalist | Policies that discourage people from having children (China's One Child Policy) |
contraception | Intentionally preventing pregnancy from occurring |
Ravenstein's Laws of Migration | A set of 11 "laws" that can be organized into three groups: the reasons why migrants move, the distance they typically move, and their characteristics. |
xenophobia | a fear or hatred of foreigners or strangers |
population distribution | a description of how individuals are distributed with respect to one another |
population density | a measurement of the number of people per given unit of land |
arithmetic densiy | the total number of people divided by the total land area |
arable land | land suited for agriculture |
physiological density | the number of people per unit of area of arable land |
agricultural density | the ratio of the number of farmers to the total amount of land suitable for agriculture |
carrying capacity | largest number of individuals of a population that an environment can support |
sex ratio | the number of males per 100 females in the population |
age cohort | people born at roughly the same time who pass through the course of life together |
population pyramid | a model used in population geography to show the age and sex distribution of a particular area |
Baby Boom | a cohort of individuals born in the USA between 1946 and 1964 which was a time of relative peace and prosperity following WW2 |
mortality | the state of being subject to death |
fertility | the production of offspring within a population |
doubling time | the number of years needed to double a population assuming a constant rate of natural increase |
natural increase | the growth rate of a population; the difference between birthrate and death rate |
demography | the scientific study of population characteristics |
demographics | statistical data relating to the population and particular groups within it |
Migration | Form of relocation diffusion involving permanent move to a new location. |
Push Factors | Incentives for potential migrants to leave a place, such as a harsh climate, economic recession, or political turmoil. |
pull factors | Positive conditions and perceptions that effectively attract people to new locales from other areas |
intervening opportunities | The presence of a nearer opportunity that greatly diminishes the attractiveness of sites farther away. |
intervening obstacles | An environmental or cultural feature of the landscape that hinders migration. |
forced migration | Human migration flows in which the movers have no choice but to relocate. |
voluntary migration | Permanent movement undertaken by choice. |
refugees | People who are forced to migrate from their home country and cannot return for fear of persecution because of their race, religion, nationality, membership in a social group, or political opinion. |

circular migration | The temporary movement of a migrant worker between home and host countries to seek employment. |
migration transition | Migration trends follow demographic transition stages. People become increasingly mobile as industrialization develops. More international migration is seen in stage 2 as migrants search for more space and opportunities in countries in stages 3 and 4. Stage-4 countries show less emigration and more intraregional migration |
net migration | The difference between the level of immigration and the level of emigration. |
step migration | Migration to a distant destination that occurs in stages, for example, from farm to nearby village and later to a town and city |
guest worker | a foreign laborer living and working temporarily in another country |
intraregional migration | Permanent movement within one region of a country. |
interregional migration | movement from one region of a country to another |
international migration | Permanent movement from one country to another. |
emigration | movement of individuals out of an area |
environmental degradation | damage to or destruction of the natural environment |
brain drain | the loss of highly educated and skilled workers to other countries |
remittances | Money migrants send back to family and friends in their home countries, often in cash, forming an important part of the economy in many poorer countries |
