We wrote a lot of notes about migration and population. We went over the growth population among regions. We talked about why population rises or decreases in different kinds of regions. We also talked about sex ratio  which is defined as the number of males per 100 females in the population. We discussed demographic transition and that is why natural rate increase and falls. In addition we talked about all the stages of transition. Stage 1 is low growth. Low growth is marked by very high birth and death rates. Stage 2 is marked by rapidly declining death rates and very high birth rates. Stage 3 is marked by rapid decline in birth rates and steady decline in death rates. Were going to take more notes the next class so we can finish up the unit. We didn't take that many notes In that current class because we had 2 hour delay and that made all of the classes short. We had a 2 hour delay because it was snowing outside really hard the previous day, so the next day the ground was slippery and there was going to be a lot of traffic so they decided to cancel school so there is no accident on the buses.
