Human Geography

Geography
CENSUS
The collection of statistics about people and activities. Intensive held every 10 years, less complete every 5 years.
DEMOGRAPHY
the statistical study of human populations.
DISTRIBUTION
Where in the world people live.
DENSITY
The number of people living in one area.
WHAT ARE THE 4 KEY MEASURES OF POPULATION?
1. Crude Birth Rate
2. Crude Death Rate
3. Emigration Rate
4. Immigration Rate
EQUATION OF NATURAL INCREASE
(birth rate) – (death rate)
CANADAS BIRTH RATE?
11
CANADAS DEATH RATE?
7
INCREASE?
0.4%
BIRTH RATE
dividing the number of births in one year by the total population and multiplying the result by 1000
DEATH RATE
dividing the number of deaths per year by the total population and multiplying the results by 1000
LIFE EXPECTANCY
the average age a person can expect to live in an area. It is a good indicator of the development of the country (high life expectancy = more developed country) vice versa
WHAT IS THE PURPOSE OF A DEMOGRAPHIC TRANSITION MODEL (DTM)?
to show how population changes as a country develops
STAGE 1 DTM: EARLY EXPANDING
-high birth rate
-high death rate
-pop. growth is slow
STAGE 2 DTM,: EXPANDING
-high birth rate
– death rate falls
– pop. rising steadily
STAGE 3 DTM: LATE EXPANDING
-falling birth rate
-low death rate
-low natural increase
-high total population
STAGE 4 DTM: CONTRACTING
-low birth rate
-low death rate
-low natural increase
-high total population
KEY INDICATORS OF HUMAN DEVELOPMENT
-life expectancy rates
-literacy rates
-infant mortality rates
-disease
-fertility
-GDP (gross domestic product)
3 POINTS OF UN HUMAN DEVELOPMENT INDEX
-literacy
-length of life
-GDP
POPULATION CHANGE EQUATION
(births) – (deaths) + immigrants – emigrants = increase or decrease in population
RULE OF SEVENTY
determines the length of time it would take for a country to double its population (Doubling time is approx. equal to 70 divided by growth rate (in percent) per year)
DOUBLING TIME
The number of years a country takes to double its population at the current birth rate
DEPENDANCY RATIO
the proportion of the population supported by the working age group
POPULATION PYRAMID
a graph that shows the age and sex structure of a population.
ECUMENE
permanently inhabited places
DETERMINING FACTORS OF POOPULATION DENSITY
climate, landscape, resources, soils, vegetation, water, accessibility, communications, culture, development, disease, government policies
GDP
total value of all goods and services produced in a country in one year.
