population geography; the study of the spatial and ecological aspects of population including: distribution, density, fertility, gender, health age, morality, migration | geodemography |
the statistical study of population size, composition, distribution, and change | demography |
population density; the number of people in an area of land usually expressed as people per square mile or kilometer | arithmetic density |
the density beyond which people cease to be nutritionally self sufficient using their particular adaptive strategy; people per arable square mile | physiological density |
land that can be used for agriculture | arable land |
annual number of births per 1000 people | birth rate |
annual number of deaths per 1000 people | death rate |
population increases due to births in the country, not form immigration | rate of natural increase |
the rule of 72; take countrys rate of annual increase, expressed as a percent, and divide it into 72 | population doubling time |
TFR; the number of children the aveage woman will bear during her reproductive lifetime (15- 44 years); less than 2.1 = decline of population | total fertility rate |
the amount of time it takes for a population to completely replace itself | replacement rate |
all industrialized, technologically advanced countries have achieved low fertility rates and stabilized or declining populations, having pass through demographic transitions | demographic transitions |
stabilized population; high birth and death rates | stage one of demographic transition |
population explosion; high birth rate, decreasing death rate | stage two |
decreasing growth, rapidly decreasing birth rate | stage three |
low birth and death rates, low grow of population | stage four |
the rapid, accelerating increase in world population since about 1650 and especially since 1900. | population explosion |
a TFR of 2.1 is needed to produce an evenly stabilized population, one that does not increase or decrease | zero population growth |
a graph used to show the age and sex composition of a population; used to compare age characteristics | population pyramid |
number of dependents:number of working age population; dependent = someone who is not working, under 15 or retired | dependency ratio |
a change in the pattern of disease in a country away from infectious diseases towards degenerative diseases; wealthy v not wealthy; diseases that can be prevented - smoking ->cancer; 1st and 3rd world countries | epidemiological transition |
a piece of land owned by one person or government, which other people can exercise their traditional rights on; rivers, lakes, ocean | commons |
famous example of community pasture; when people pursue self interest it results in overgrazed pasture, not enough resources; "Freedom in a common brings ruin to all"; flaw: common property v. open access resources | Hardin's "tragedy of the commons" |
system of customary law and traditional practices used on resources | common property resources |
free for all | open access resources |
movement of people with livestock seasonally | transhumance |
the cultivation of domesticated crops and the raising of domesticated animals | agriculture |
plant: deliberately plated, protected, cared for, and used by humans; animal: depends on people for food and shelter and that differs from wild species in appearance and behavior as a result of controlled breeding and frequent contact with humans | domestication |
less expensive, placing seeds directly into soil | seed propagation |
make copies of plant with similar genetic composition by layering or prerooting | vegetative propagation |
