We got our Population test back today and reviewed the
answers. Here are some things that were on the test. Deaths per thousand people
per year is the crude death rate. The average number of children born per woman
is the totally fertility rate. The rate of natural increase can be measured by
subtracting the birth rate from the death rate. The net migration rate is the
difference between the amount of immigrants and emigrants. We use population
pyramids to give us information about population, broken down by age and sex.
Life expectancy is the average number of years to be lived by a group of people
born the same year. Did you know that Canada has a higher net migration rate
than both the U.S and Mexico? This is because people are going to Canada for
its health care benefits. Anyway, I got an 88 on the test so I guess I did
pretty good!
