We reviewed everything we learned for the test tomorrow.
Like how a “crude death rate” is the number of deaths per 1000 of the
population. The “crude birth rate” is the number of babies born in a year per
1000 of the population. An immigrant is a person who enters a new country and
an emigrant is a person who leaves a country. To find the net migration rate
you subtract the amount of emigrants from the amount of immigrants. If more
people are coming in than the NMR is positive. If not then it’s negative. The
rate of natural increase is when you take the death rate subtracted by the
birth rate then divide it by 10. Life expectancy is the average number of years
to be lived by a group of people. Push forces are things that make you want to
leave a country and pull forces is things that make you want to live in a
country. Finally, total fertility rate is the average number of children born
per women. If the average fertility is 2.1 then a population stays the same.
NOW IM READY FOR THE TEST!
