In class today, we took notes on a power point presented by
Mr. Schick. One thing that we learned in the power point is that there are over
seven billion people on the planet right now. Of this, ninety percent of the growth
population happens in the places such as Africa, South and East Asia, and Latin
America. We also learned about Life
Expectancy. Life Expectancy is the average number of years to be lived by a
group of people born in the same year. In the United States, it is 78.49 years.
Crude Birth Rate is the number of births per 1,000 of the population. Crude
Death Rate, is exact same but instead the number of deaths. Net Migration rate
is the difference between the number of persons entering and leaving a country
during a year. The United States has a NMR of 3.62. People migrate for multiple
reasons. First, there are push forces, which include civil wars, environmental degradation,
unemployment, and religious or ethnic persecution. Second, there are pull
forces such as better economic opportunity, better healthcare services, and
religious or political freedom. The Total Fertility Rate is the average number
of children born per women. All these things represent what kind of world we live
in and how diverse it really can be.
