Population

population growth rate

birth rate - death rate + immigrants - emigrants = population growth rate

*birth rate

*number of infants born per 1,000 people (in a specified area during a specified period of time)

*mortality (death) rate

*number of people who die per 1,000 people (in a specified area during a specified period of time)

*infant mortality rate

*number of babies who die before the age of 1 per 1,000 live births (in a specified place during a specified time)

life expectancy at birth

the average number of years a person can expect to live

*GDP per capita (PPP)

*total amount of a nation's production divided by the number of people who live there

*total fertility rate

*average number of babies that women in a specified area are expected to have in their lifetimes

*life expectancy at birth

*the average number of years a group of newborns that are born in the same year can be expected to live if mortality at each age remains constant in the future

net migration rate

number of people moving to a country - number of people moving out of a country = net migration rate

replacement rate

fertility rate of 2.1

immigrate

moving to another country

emigrate

moving from another country

*population density

*number of people living in a specified area (usually a square mile) - determined by taking the population and dividing it by the size (area)
