Unit 2 Flashcards
(64 cards)
Pattern of human settlement. The spread of people across the earth
Population distribution
The measure of the average population per square mile or kilometer of an area
Population density
Calculated by dividing a regions population by its total area
Arithmetic population density
Calculated by dividing population by the amount of arable land
Physiological population density
Land suitable for growing crops (farm land)
Arable land
Compares the numbers of farmers to the area of arable land
Agricultural population density
Having more people than it can support
Overpopulation
The number of people a region can support without damaging the environment
Carrying capacity
Population pyramid (also known as)
Age/Sex composition graph
Based on age and gender data. This can provide information about birth rates, death rates, how long people live on average, and economic development. Can give evidence of past events.
Population pyramid
Number of live births per year per 1000 people.
Crude birth rate (CBR)
Average number of children who will be born per woman of that group in a country assuming every woman lived through her childbearing years.
Total fertility rate (TFR)
The average number of years people live.
Life expectancy
The number of children who die before their first birthday.
Infant mortality rate
The number of deaths per year per 1000 people.
Crude death rate (CDR)
The percentage at which a countries population is growing or declining, without the impact of migration.
Rate of natural increase (RNI)
The time it takes for a population to double in size. (uses equation called the rule of 70….70 divided by growth rate per year)
Population doubling time
Shows 5 typical stages of population change that countries experience as they modernize.
Demographic transition model (DTM)
Extension of the DTM. Explains the changing death rates and more common causes of death within societies.
Epidemiological transition model (ETM)
The belief that food production would increase arithmetically-growing steadily by a similar amount each generation. In contrast, he believed that people would not limit the number of children they had so the population would increase exponentially-growing steadily by a similar percentage each generation.
Malthusian theory
Suggested that the more people there are the more hands there are to work, more than just more mouths to feed.
Boserup theory
Argues that population growth is a serious problem currently and an even greater threat to the future.
Neo-Malthusian
These policies attempt to decrease the number of births in a country and are often used by developing countries.
Anti-natalist policies
Programs designed to increase the fertility rate.
Pro-natalist policies
