Population Flashcards
Demography
Study of the population
Population density
Measures how closely people live, dividing the number of people in a place by a given area
Crude birth rate
Babies born in a year for every 1000 people
Crude death rate
Number of deaths in a year for every 1000 people
Rate of natural increase
Statistic formed by the subtraction of the crude death rate from the crude birth rate; rate the population is increasing by without taking into account the movement of people (ex. immmigration)
Doubling time
Found by dividing the growth rate by 70, amount of time needed for the population to double
Total fertility rate
Number of children a woman is expected to have in her lifetime
Replacement rate
TFR needed to ensure the population continues to grow, 2.1
Population momentum
Tendency for a population to grow even when TFR drops below replacement rate, a result of larger numbers of child-bearing individuals compared to dying older individuals
Population projection
Prediction about the future population based on current trends
GNI
Gross National Income, the total value of all goods and services produced in a country together with the balance of income from and payments to other countries
PPP
Purchasing Power Parity, a measurement of the number of units of a country’s currency needed to buy the same amount of goods in a country as 1 US dollar could buy
Demographic transition model
Pattern of population growth as a country develops
Megacity
City of 10 million or more people
Slums
Concentration of very poor people in a city
Urban sprawl
Spread of a city across a large area of land, often in an unplanned way
Forced migrant
Condition in which a person has no choice but to relocate
Refugees

Asylum seekers
Refugees whose claims are still being considered
IDPs
Internally Displaced Persons, those who have been forcibly relocated within their own nation
Victims of human trafficking
People who have been forcibly removed because of deception and/or coercion, a form of modern slavery
Life expectancy
Average number of years a person is expected to live for
Dependency ratio
Dependents divided by the economically active
Ageing ratio
The old (over 65) divided by the economically active
Demographic dividend
Bulge in the number of adults in a population that occurs over time due to a gradually declining fertility rate
