Studied by 2 people
Population geography
provides the background concepts and theories to understand and forecast the size, composition, and distribution of the human population
Demography
the statistical study of the human population, is concerned with spatial analysis—location, density, pattern, and relationship to the physical environment.
2017
the population hit 7.5 billion and added an extra 230,000 thousand humans a day
Rates
record the frequency of occurrence of an event during a given time frame for a designated population
Cohort
population group unified by a specified temporal characteristic—the age cohort of 0–4 years, perhaps, or the college class of 2025
Crude birth rate (CBR)
referred to simply as the birth rate, is the annual number of live births per 1,000 population
Total fertility rate (TFR)
more refined and thus more accurate measure for showing the rate and probability of reproduction among fertile females, the only segment of population capable of bearing children
Crude death rate (CDR)
also called the mortality rate, is calculated in the same way as the CBR: the annual number of events per 1,000 population
Infant mortality rate
significant because that is where the greatest declines in mortality have occurred
Population pyramid
powerful means of visualizing and comparing a population’s age and sex composition
Change in population
occurs when someone is born, migrates or dies
Pf
Pi + births + in-migration - deaths - out-migration
Physiological density
provides a measure of the population pressure exerted on agricultural land
Agricultural density
excludes city populations from the physiological density calculation and reports the number of rural residents per unit of agriculturally productive land
Overpopulation
situation in which an environment or territory cannot support its present population and involves many factors other than just population density
