- 1Doubling TimeThe time it takes for a population to double
- 2Sex RatioThe ratio of men to women in a population
- 3Rate of Natural increaseThe rate of a population increases
birth rate minus death rate - 4J-curvethe trend of a country's trade balance following a devaluation or depreciation under a certain set of assumptions.
- 5Neo-Malthusianadvocating control of population growth
- 6Rufugeea person who has been forced to leave their country in order to escape war, persecution, or natural disaster.
- 7push-pull factorsThe push factor involves a force which acts to drive people away from a place and the pull factor is what draws them to a new location
- 8Chain MigrationRefers to the endless chains of foreign nationals who are allowed to immigrate because citizens and lawful permanent residents are allowed to bring in their non-nuclear family members.
- 9Disease DiffusionThere are two types, contagious and hierarchical. Hierarchical is along high density areas that spread from urban to rural areas. Contagious is spread through the density of people. This is important in determining how the disease spread so you can predict how it will spread.
- 10Malthus, ThomasA population theorist who said: food production = linear; human reproduction = geometric; despite natural checks (famine, disease) ... will always be overpopulation; he brought up the point that we may be outrunning our supplies because of our exponentially growing population. He is important to geography because people today still shape their theories around his.
- 11Overpopulationrelationship between the number of people on Earth, and the availability of resources. It is important to geography because problems result when an area's population exceeds the capacity of the environment to support them at an acceptable standard of living. The Southern part of India is overpopulated
- 12Population pyramidis two back-to-back bar graphs, one showing the number of males and one showing females in a particular population in five-year age groups. This is important because you can tell from the age distribution important characteristic of a country, whether high guest worker population, they just had a war or a deadly disease and more.
- 13Underpopulationit is the opposition to overpopulation and refers to a sharp drop or decrease in a region's population. It is important to geography because it helps show natural increase.
- 14Zero population growthwhen the crude birth rate equals the crude death rate and the natural increase rate approaches zero. It is important to geography because it shows natural increase, and how the population is changing.
- 15Activity spacespace allotted for a certain industry or activity. Can apply to an area within a city or surrounding a central place.
- 16Gravity modelPredicts that the optimal location of a service is directly related to the number of people in the area and inversely related to the distance people must travel to access it.
- 17Periodic movementmovement that involves temporary, recurrent relocation (e.g., military service, migrant workers, college attendance ) This is important to geography because it will show how there is different movement within a country.
- 18Population projectionpredicts the future population of an area or the world. Helps predict future problems with population such as overpopulation or under population of a certain race or ethnicity.
- 19Age Distributiona model used in population geography that describes the ages and number of males and females within a given population; also called a population pyramid
- 20Population DistributionVariation of population density over a particular geographic area. For example, a country has a high population density in its urban areas and a much lower population density in rural areas.
- 21CohortA population group unified by a specific common characteristic, such as age, and subsequently treated as a statistical unit.
- 22Distance Decaythe effects of distance on interaction, generally the greater the distance the less interaction
- 23Sustainabilitythe ability to meet humanities current needs without compromising the ability of future generations to meet their needs; the 3 components of sustainability are economy, environment, and society (culture)
- 24Carrying Capacitylargest number of individuals of a population that a environment can support
- 25Personal Spacehow people distance themselves from one another
- 26Demographic Transition ModelA sequence of demographic changes in which a country moves from high birth and death rates to low birth and death rates through time.
- 27Demographic Momentumthis is the tendency for growing population to continue growing after a fertility decline because of their young age distribution. This is important because once this happens a country moves to a different stage in the demographic transition model.
- 28Epidemiological Transition ModelThe theory that says that there is a distinct cause of death in each stage of the demographic transition model. It can help explain how a country's population changes so dramatically.
- 29Demographic RegionsRegions grouped together by the stage of the demographic transition model that most countries in the region are in. Cape Verde (Africa) is in Stage 2 (High Growth), Chile (Latin America) is in Stage 3 (Moderate Growth), and Denmark (Europe) is in Stage 4 (Low Growth). This is important because it shows how different parts of the world are in different stages of the demographic transition
- 30Standard of Livinga level of material comfort in terms of goods and services available to someone
