Demographic Transition model | Has 5 steps. Stage 1 is low growth, Stage 2 is High Growth, Stage 3 is Moderate Growth, and Stage 4 is Low Growth and Stage 5 although not officially a stage is a possible stage that includes zero or negative population group. This is important becau |
Age Distribution: | (Population pyramid) is 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 |
Carry capacity | This is the population level that can be supported, given the quantity of food, habitat, water and other life infrastructure present. This is important because it tells how many people an area will be able to support. |
Cohort: | Population of various age categories in an age-sex population pyramids. This is important because this can tell what state this country it is whether in Stage 3 or Stage 5 in the demographic transition model. |
Demographic equation | The formula that calculates population change. The formula finds the increase (or decrease) in a population. The formula is found by doing births minus deaths plus (or minus) net migration. This is important because it helps to determine which stage i |
Demographic momentum | this 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. |
Demographic regions | Cape Verde is in Stage 2 (High Growth), Chile is in Stage 3 (Moderate Growth), and Denmark 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. |
Dependency ratio | The number of people who are too you or too old to work compared to the number of people in their productive years. This is important because this tells how many people each worker supports. For example the larger population of dependents, the greater |
Diffusion of fertility control | The diffusion of fertility control is spread throughout the world. In the U.S it’s below 2.1 in much of Africa it is above 4, if South America is between 2 and 3, in Europe it is below 2.1, in China and Russia it is below 2.1, and in much of the Middl |
Disease diffusion | There 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 pr |
Doubling time: | The number of years needed to double a population, assuming a constant rate of natural increase. This is important because it can help project the countries population increase over the years and when its population will double. |
Ecumene | The proportion of earths surface occupied by permanent human settlement. This is important because its tells how much of the land has been built upon and how much land is left for us to build on. |
Epidemiological transition model: | This is a distinctive cause of death in each stage of the demographic transition. This is important because it can explain how a countries population changes so dramatically and more. |
Gendered space: | It is a place where only members of one gender goes |
Infant mortality rate | (IMR) The annual number of deaths of infants under one year of age, compared with total live births. Its is expressed as the annual number of deaths among infants among infants per 1000 births rather than a percentage. This is important because it te |
J-curve: | This is when the projection population show exponential growth; sometimes shape as a j-curve. This is important because if the population grows exponential our resource use will go up exponential and so will our use as well as a greater demand for food |
Maladaption | This is an adaptation that has become less helpful than harmful. This relates to human geography because it has become less and less suitable and more of a problem or hindrance in its own right, as time goes on. Which shows as the world changes so do th |
Malthus, Thoma | Was one of the first to argue that the worlds rate of population increase was far outrunning the development of food population. This is important because he brought up the point that we may be outrunning our supplies because of our exponentially growin |
Mortality | There are two useful ways to measure mortality; infant mortality rate and life expectancy. The IMR reflect a country’s health care system and life expectancy measures the average number of years a baby can expect to live. This is important because you c |
Natality | Crude Birth Rate) This is the ratio of live births in an area to the population of that area; it is expressed as number of birth in year to every 1000 people alive in the society. This is important because it tells you the rate a country is having babies |
Neo-malthusian | theory that builds upon Malthus’ thoughts on overpopulation. Takes into count two factors that Malthus did not: population growth in LDC’s, and outstripping of resources other than food |
Overpopulation | relationship between the number of people on Earth, and the availability of resources |
Population densities- | the frequency with which something occurs in space is density |
Arithmetic density | otal number of objects in an area. Used to compare distribution of population in different countries. |
Physiological density | number of persons per unit of area suitable for agriculture. Could mean a country has difficulty growing enough food. |
Agricultural density | he number of farmers per unit of area of farmland. May mean a country has inefficient agriculture. |
Population distributions | he arrangement of a feature in space is distribution. Geographers identify the three main properties as density, concentration, and pattern |
Population explosion | a sudden increase or burst in the population in either a certain geographical area or worldwide |
Population projection | predicts the future population of an area or the world |
Population pyramid | population displayed by age and gender on a bar graph |
Rate of natural increase | the percentage by which a population grows in a year. CBR-CDR = NIR Excludes migration |
S-curve- | traces the cyclical movement upwards and downwards in a graph. So named for its shape as the letter "s" |
Sex ratio | the number of males per hundred females in the population |
Standard of livin | refers to the quality and quantity of goods and services available to people and the way they are distributed within a population |
Sustainability | providing the best outcomes for human and natural environments both in the present and for the future |
Underpopulation | it is the opposition to overpopulation and refers to a sharp drop or decrease in a region’s population |
Zero population growth- | when the crude birth rate equals the crude death rate and the natural increase rate approaches zero. |
Activity space | space allotted for a certain industry or activity |
Chain migration | when one family member migrates to a new country and the rest of the family follows shortly afte |
Cyclic movement | trends in migration and other processes that have a clear cycle |
Distance Decay | When contact between two groups diminishes because of the distance between them |
Forced Migration | People removed from there countries and forced to live in other countries because of war, natural disaster, and government. ( |
Gravity Model | Predicts 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. |
Internal Migration | Permanent movement within a particular country |
Intervening Opportunity | An environmental or cultural feature of the landscape that helps migration |
Migration Patterns: Intercontinental | Permanent movement from one country to a different country on the same continent |
Interregional | Permanent movement from one region of the country to another |
Rural-Urban- | Permanent movement from suburbs and rural area to the urban city area |
Migratory Movement- | movement of people from one place to another due to different factors |
Periodic Movement- | motion that recurs over and over and the period of time required for each recurrence remains the same |
Personal Space- | region surrounding a person which they regard as psychologically theirs. |
Place Utility | The process of increasing the attractiveness of a product to a group of consumers by altering its physical location |
Push-Pull Factors | Factors that induce people to leave old residence and move to new locations. |
Space-Time Prism | set of all points that can be reached by an individual given a maximum possible speed from a starting point in space-time |
Step Migration | migration pattern that consists of a series of small, less extreme locational changes |
