provides the background tools and understandings of theose interests. It focuses on the number, composition, and distribution of human beings in relation to variations in the conditions of earth. space.
|
Population geography
|
|
|
the statistical study of human population
|
demography
|
|
|
is the annual number of live births per 1000 population.
|
crude birth rate (CBR)
|
|
|
is a more refined and thus more satisfactory statement than the crude birth rate for showing the rate and probability of reproduction among fertile females, the only segment of population bearing children.
|
total fertility rate
|
|
|
is calculated in the same way as the crude birth rate; the annual number of events per 1000 population.
|
crude death rate (CDR)
|
|
|
a graphic device that represents a population's age and sex composition.
|
population pyramid
|
|
|
is a simple measure of the number of ecomomic dependents, old or young, that each 100 people in the productive years must support.
|
dependency ratio
|
|
|
is derived by subtracting the crude death rate from crude birth rate.
|
rate of natural increase
|
|
|
the rate of increase can be related to the time it takes for a population to double if the current growth rate remains constant.
|
doubling time
|
|
|
a curve shaped like the letter J, depicting expinential or geometric growth (1,2,4,8,16...)
|
J-curve
|
|
|
one attempt to summarize a historically observed voluntary limitation of population growth-and relating that control to economic development.
|
demographic transition
|
|
|
summarizes the contrbution made to regional population change over time by the combination of natural change and net migration
|
demographic equation
|
|
|
applied to permanently inhabited areas of the earth's surface.
|
ecumene
|
|
|
the uninhibited or very sparsely occupied zone
|
nonecumene
|
|
|
a measurement of the numbers of persons per unit area of land within predetermined limits, usually political or census boundaries.
|
population density
|
|
|
one attempt to summarize a historically observed voluntary limitation of population growth-and relating that control to economic development.
|
demographic transition
|
|
|
summarizes the contrbution made to regional population change over time by the combination of natural change and net migration
|
demographic equation
|
|
|

|
ecumene
|
|
|
the uninhibited or very sparsely occupied zone
|
nonecumene
|
|
|
a measurement of the numbers of persons per unit area of land within predetermined limits, usually political or census boundaries.
|
population density
|
|
|
is the most common and least satisfying expression of that variation. It is the calculation of the number of people per unit area of land, usually within the boundaries of a political entity.
|
crude density or arithmetic density
|
|
|
When total population is divided by arable land area alone. an expression of population pressure exerted on agricultural land.
|
Physiological density
|
|
|
it simply excludes city populations from the physiological density calculation and reports the number of rural residents per unit of agriculturally productive land.
|
Agricultural density
|
|
|
a value judgement reflecting an observation or a conviction that an environment or a territory is unable adequately to support its present population.
|
Overpopulation
|
|
|
the number of people an area can support on a sustained basis, given the prevailing technology.
|
Carrying capacity
|
|
|
estimates of future population size, age, and sex composition based on current data.
|
population projections
|
|
|
an English economist and demographer
|
Malthus
|
|
|
the horizontal bending, or leveling, of an exponential J-curve.
|
S-curve
|
|
|
when the population is equivalent to the carrying capacity of the occupied area
|
homeostatic plateau
|
|
|
The advocacy of population control programs to preserve and improve general national prosperity and well-being.
|
Neo-Malthusianism
|
|
|
The tendency for population growth to continue despite stringent family planning programs because of a relatively high concentration of people in the childbearing years.
|
Population Momentum
|
|
|
records the frequency of occurrence of an event during a given time frame for a designated population
|
Rates
|
|
|
measures that refer to data to a population group unified by a specified common characteristic
|
Cohort
