In Human Geo today we talked more about population. We learned about the next migration rate: the difference between the number of persons entering and leaving a country during a year. We learned about immigration (excess of people entering a country, written as a positive number, and an example is that Canada has 5.56 migrants per 1,000 population and the US has 2.45, but it was 3.62 last year) and emigration (excess of people leaving the country, written as a negative number, and an example would be that Mexico has -1.68 migrants per 1,000 population, -3.61 two years ago, and -3.11 last year). We also talked about why people migrate. They either migrate because of push forces or pull forces.
push forces
- unemployment or underemployment
- religious or ethnic persecution
- civil war
- environmental degradation
pull forces
- better economic opportunity
- better health services
- religious freedom
- political freedom
We learned about fertility rate too. TFR is the average number of children born per woman. And for a population to remain the same, the TFR must be 2.1. If it is higher than 2.1, the population rises, and if it is below, it decreases. It's a huge difference if you compare the TFR of Nigeria (6.89) and the TFR of Japan (1.40).
Mr. Schick also used me and my desk as an example of migration.
