Population Geography

What are some factors that have contributed to world population

growth?

Population Statistics

_______ Rate– number of live births per 1000 people per year

______________ Rate (Death Rate) – number of deaths per 1000 people per year

Rate of _____________ _____________ (Population Growth Rate) – difference between Birthrate and Mortality Rate

Birthrate – Death Rate = Rate of Natural Increase

Population Statistics

Fertility Rate – the average number of children that would be born per woman

If all women lived to the end of their childbearing years

If all women gave birth according to the rate at each age

Current replacement rate is ___ children per woman

Infant Mortality Rate – the number of deaths among infants (_____ year of age or younger) per thousand live births

Shows _______ and ___ distribution of a population Allows geographers to examine how events affect

the population of a country or region _______, _______________, epidemics, etc.

Shows population proportion Young People (0 – ____) Working People (15 – _____) Elderly People (60 +)

How to Read a Population Pyramid

1)Read the title (Country, City, or Racial Group)

2)Comment on general shape of the pyramid

3)Note the proportion of people in various age groups

4)Note the gender ratio

5)Interpret the data

Population Density

The average number of people that live in a measurable area

Shows how heavily populated an area is Found by dividing total _________________ in an

area by the total __________________ they occupy

Things to remember: Population density can change over time Can be misleading due to uneven distribution

Carrying Capacity

The number of people a piece of land can support Increased due to:

Fertile Soil Abundant Resources Technology Wealth

_________________ occurs when the given resources of a piece of land can not support the number of people living on it
