Changing Populations Flashcards
Demography
-the study of population numbers, distribution, trends, and issues
Birth Rate
Yearly number of live birth per 1000
Death Rate
Yearly number of deaths per 1000
Natural Increase Rate
The difference between the birth rate and the death rate
Birth Rate - Death Rate =
Natural Increase Rate
Infant Mortality Rate
Yearly number of deaths under 1 year old per 1000
Immigrate
To move permanently to a country other than your own native country
Immigration Rate
Number of new Canadians who have immigrated here from another country
Immigrant
A person who moves to a new country
Refugee
A person who immigrates to another country out of fear of persecution in his or her own country
Emigrate
To leave your country of orgin to live elsewhere
Emigration Rate
Yearly number of people per 1000 who move elsewhere
Immigration Rate - Emigration Rate =
Net Migration Rate
Push Factor
Something that makes people want to leave their country and move to another (i.e. war, famine, disease, discrimination, unemployment)
Pull Factor
Some that attracts people to another country (i.e. educational opportunities, emloyment opportumities, freedom of speech)
Population Growth Rate
Natural Increase + Net Migration
Life Expectancy
The average lifespan of a population (men/women)
Baby Boom
The large rise in the birth rate experienced by many countries in Europe and North America between 1949 and 1961
Doubling Time
How long would it take for a country’s population to double at that country’s current rate of population growth.
Rule of 70
The calculcation that determines the number of years it will take for a country’s population to double
Population Pyramid
Graph that depicts population distribution by age and sex
Population Density
Figure caluclated by dividing the population of a region by that region’s area
Population Distribution
A pattern showing where people live in an area
Describe stage one of a demographic transition model
Both the death rate and the birth rate are high. The natural increase rate is stable or slow. Many children are needed for farming children die at an early age. This is because of poor medical knowlege. The population pyramid is in the shape of a pyramid. This is found in a few remote groups.
