Today in class, we started a new lesson called Population and Migration. Here are the definitions we will be needing for this lesson.
life expectancy- the expected number of years left in a persons life at any given age.
crude birth rate (CBR)- number of births in a population each year.
crude death rate (CDR)- number of deaths in a population each year.
developing nations- a nation with an overall low standard of living.
developed nation- a nation that has a high standard of living.
rate of natural increase (RNI)- the crude birth rate minus the crude death rate of a population.
net migration rate (NMR)- the difference of immigrants and emigrants of an area in a period of time.
immigration- the movement of other people into a nation of which they are not native to.
emigration- the movement of other people into a nation of which they are not native to, but intend to settle there permanently.
push forces- factors that make people want to leave a nation.
pull forces- factors that make people want to live in another nation.
total fertility rate (TFR)- average number of children that would have been born to a woman over her lifetime.
