Unit 2 vocab: Population Flashcards
Compares the number of farmers to the area of arable land.
Agricultural population density
Calculated by dividing the population by the amount of arable land.
Physiological population density
Calculated by dividing a region’s population by its total area.
Arithmetic population density
Land suitable for growing crops (farmable land).
Arable
The pattern of human settlement- the spread of people across the earth. Representing it on a map highlights places that are crowded, sparsely settled, or even empty.
Population distribution
Measures of average population per square mile or kilometer. Measures how crowded a place is.
Population density
Hierarchical division of people into groups based on factors such as economic status power and or ethnicity.
Social stratification
Having more people than a region can support.
Overpopulation
The number of people a region can support without damaging the environment.
Carrying capacity
A most useful tool to study population (age-sex composition is called.
Population pyramid
The vertical axis shows age groups known as.
Cohorts
The slowdown of births.
Birth deficit
Once hostility ends and peace resumes, the birth rate often spikes, causing what is known as.
baby boom.
Once the boom ends, birth rates are lower for a number of years,
baby bust. This baby bust continues until the boomers reach childbearing age.
Since this increase reflects an earlier baby boom, it is called an-
echo
The group is expected to be the society’s labor force.
Potential workforce
People under 15 or over 64 because they are too young or too old to work full time.
Dependent population
The comparison between the size of the two groups
Dependency ratio
Used to describe the future population of a region of any scale.
Demographic balancing equation
The number of live births per year for every 1,000 people.
Crude birth rate
The number of children who would be born per woman in that group in a country, assuming every woman lived through her childbearing years.
Total fertility rate
The average number of years people live
Life expectancy
The number of children who die before their first birthday.
Infant mortality rate
Number of deaths per year for every 1,000
Crude death rate
The percentage at which a country’s population is growing or declining without the impact of migration.
RNI- rate of natural increase
Population growing exponentially and can be estimated using Rule of 70
Population double time
Shows five typical stages of population change that countries experience as they modernize.
Demographic transition model
As countries transition from early Stage 3 into Stage 4, population will continue to grow for at least one generation
Demographic momentum
Omran’s work identifies predictable stages in disease and life expectancy that countries experience as they develop.
Epidemiological transition model
Suggest that the more people there are, the more hands there are to work, rather than just more mouths to feed.
Boserup Theory
People that accept Malthu’s fundamental premise as correct today.
Neo-Malthusians
These policies attempt to decrease the number of births in a country.
Anti natalist policies
Programs designed to increase fertility rate.
Pronatalist policies
Average number of children who would be born per woman of that group in a country.
Total fertility rate (TFR)
