Population Terms, Demographic Transition, Epidemiological Transition, and Population Pyramids.
What is Demography?
The study of population
What do geographers care about in regard to population?
- The population size
- The rate of increase of world population (most growth has been in less developed countries over the last 100 years)
- The unequal distribution of population growth

What is Density?
The population density measured as the number of people per unit area of land
What is Physiological Density?
The number of people per unit area of arable
What is Agricultural Density?
The number of farmers per unit area of arable land
What is Carrying Capacity?
The number of people, other living organisms, or crops that a region can support without environmental degradation.
Describe a Population Pyramid.
A diagram that gives information about the proportion of males and females in each age group.
What do the different shapes of population pyramids mean in relation to population growth and types of communities they represent?
Wider base = Growing population
Diamond = Shrinking population
“Building” = Stable population
What is Crude Birth Rate?
Number of births per 1,000
What is Crude Death Rate?
Number of deaths per 1,000
What is Natural Increase Rate?
Crude Birth Rate - Crude Death Rate = Natural Increase Rate
What is Doubling Time?
Amount of time it takes for a population to double if Natural Increase Rate (NIR) stays stable
What is Total Fertility Rate?
Average number of children a woman will have
What is Infant Mortality Rate?
Average number of children who die before their first birthday
What is Life Expectancy?
Average number of years a person lives
What is the Dependency Ratio?
The percentage of people under age of 15 and over the age of 65
