10/30

Today in human geo we started off by getting out tests back... or at least the objective parts, and I got a 92!! Then we got into talking about life expectancy. Life expectancy is the average number of years to be lived by a group of people born in the same year. We talked about thing thats effect life expectancy and also where life expectancy is high, like Moraco, and where it's low, like Chad. Then we discussed crude death rate and crude birth rate (number of deaths or births per 1000). We also got into rate of natural increase- which is derived by subtracting death rate from birth rate. Then we began to talk about migration and how t effects al this. We discussed the difference between immigration and emigration. Immigration is when you come into a country and emigration is when you are leaving a country. We then talked a little abut how this affects net migration rate- which is the difference between the number of people entering and/or leaving a country in a year. That is where we left off at the end of class.
