The way in which people are spread out
across the globe
Population densityThe number of people living in a given area, usually a square km

The difference between birth and death rate
The Crude Birth RateThe number of live
births per 1000 people per year
Crude Death RateThe number of deaths per 1000 people per
year
Population Growth Rate
Any natural change in population either an
increase or a decrease
The Demographic Transition Model
A sequence of changes over a period of time in
the relationship between birth rates death rates and overall population
Population Age-sex Pyramid
A representation of male-female population
at different ages in a particular location
Average Life Expectancy
The number of years an average person born in an area may expect to

Economically active population
Those people aged 15-65 employed in work

Those people aged 15 or over 65 who do not
work
The Dependency Ratio The proportion of a
population who rely on the working population
The Fertility RateThe number of children born to women of child
bearing age
The replacement ratioWhen there are just
sufficient children born to balance the number of people who die – In
MEDCs around 2.1 births per woman
MEDCMore economically
developed country, e.g. Japan, USA, UK
LEDCLess economically
developed country, e.g. Ghana, Chile, Afghanistan
MigrationA movement of people usually to a permanent
