unit two vocab Flashcards
aging population
older people are increasing
agriculture population frequency
the number of farmers per unit of area of farmland. May mean a country has inefficient agriculture.
arithmetic population density
The total number of people divided by the total land area. This is what most people think of as density; how many people per area of land.
carrying 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.
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 as well as how fast you can expect that population to grow.
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 because this is the way our country and others countries around the world are transformed from a less developed country to a more developed country.
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 financial burden on those who are working to support those who cannot.
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.
infant mortality rate
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 tell how developed a country is, if they have a high IMR they are an LDC and if it is low they are an MDC.
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 can use a countries mortality rate to determine important features about a country.
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
physiological population density
The number of people per unit of area of arable land, which is land suitable for agriculture. This is important because it relates to how much land is being used by how many people.
population density
the frequency with which something occurs in space is density
population distribution
the arrangement of a feature in space is distribution. Geographers identify the three main properties as density, concentration, and pattern
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 of a country, whether high guest worker population, they just had a war or a deadly disease and more.
