Unit 1 Populations In Transition Flashcards
What is carrying capacity?
The number of people that the world’s resources can support using the technology that exists at the time.
What is “Birth rate”
The number of births in a country for every thousand people in the population. Over 30 considered high, less than 15 considered low.
(#of babies born/population x 1000)
What is “death rate”?
Number of deaths in a country for every thousand people in the population. Over 30 is high, under 15 is low. (#of deaths/population x1000)
What is the “Natural Increase Rate?”
The difference between a country’s birth rate and death rate. (Birth-death)
What is “Immigration Rate”?
Measures the number of people who permanently move to a country. (#of immigrants/population x1000)
What is “Emigration Rate”?
The number of people who permanently leave a country. (#of emigrants/population x1000)
What is “Net Migration Rate”?
Difference between immigration and emigration rates. (Immigration - emigration)
What is “Population Growth Rate”?
The rate at which a country’s population is changing. (Natural increase + net migration rate)
What is the “Dependency Load”?
The percentage of a country’s population that is under 14 and over 65 that must be supported by independent working population.
What is the “dependency ratio”?
The ratio of “dependent” people to those who are “working”
Population 14 and under + population 65+ / working population x100
What is “Infant Mortality Rate”?
The number of children in a country who die in the first year of life for each 1000 births.
What is “Life Expectancy”?
The average lifespan, at birth, of a human being.
What is a population pyramid?
A type of graph that shows the age and gender structure of a population.
What is “Total Fertility Rate”?
The average number of children that each woman will have in her fertile years (between ages of 15-45)
What is the “Replacement Rate”?
The total fertility rate that produces a natural increase rate of 0.
What can you learn from a population pyramid?
Life expectancy, infant mortality rate, the dependency load, whether the country is developed or undeveloped, etc.
What are the stages in the Demographic Transition Model?
Pre-Transition, Early Transition, Late Transition, Post Transition, Population Decline
Describe Stage 1 of the DTM
Pre-Transition
- high birth rates and death rates
- low pop. growth
- high birth rates (no birth control)
- high infant mortality (parents have many children hoping for survival)
- high death rates (famine, disease, lack of medical knowledge)
Describe Stage 2 of the DTM
Early Transition
- declining death rates
- more food and sanitation
- high birth rates (tradition)
- religion maintains large families
- natural increase at greatest
Describe Stage 3 of the DTM
Late Transition
- birth rates fall (control)
- lower infant mortality
- industrialized, fewer labourers
- women choose career paths that affect amount of children born
- increased desire to buy things (could not be afforded if families were larger)
