Today all we did in class was go over a little about the test we have on Friday. Some questions were what is the life expectancy of the united states and we would have to find that out on the cia world Facebook. And now I know that that will be one part of the test, looking at countries and finding their life expectancies. Also we will need to know about the population triangles and the graphs. Here are the words we need to know.

crude birth rate (CBR)

crude death rate (CDR)

rate of natural increase (RNI)

net migration rate (NMR)
