Today in Human Geo class we looked at a power point and took notes about it.  The Power point was about Population and settlement. We learned that their are 7 billion people on the planet right now. Also, we learned that 90% of the population growth takes place in the developing countries Africa, South and East Asia, and Latin America. We learned that life expectancy is the average number of years to be lived by a group of people born in the same year. We learned that crude birth rate is the number of births per 1000 of the population and that crude death rate is the number of deaths per 1000 of the population. We also learned that most people migrate because its a push or pull. A push would be a civil war, environmental degradation, and religious persecution. A pull would be religious and political freedom, better health services and better economic opportunity.
