In human geo today we reviewed the test we took on Friday and I got to fix my mistakes. I learned that TFR means "Total Fertility Rate" and RNI means "Rate of Natural Increase". I also learned that Out of Mexico, United States and Canada the country with the highest migration rate is Canada. Also today I learned that Sudan was the largest pyramid with the biggest baby/kids population. There is so many kids and babies being born in Sudan and that makes up a lot of their population.
