Crude Birth Rate and Crude Death rate/ Migration

Today in class, we talked about measuring the population using crude birth and crude death rate. Crude birth rate is the number of births per 1,000 of the population. Crude death rate is the number of deaths per 1,000 of the population. Below is the rate of natural increase (RNI) information.

Rate of Natural Increase (RNI)

• produced by subtracting the death rate from the birth rate.
• this gives us the annual natural growth- in percentage form- for a country or a region.

But don't forget about migration:

Net migration rate- the difference between the number of persons entering and leaving a country during a year.

Why do people migrate?

Push Forces:

• Civil War
• Environmental Degradation
• Unemployment
• Religious or ethnic persecution

Pull Forces:

• better economic opportunities
• better health services
• religious freedom
• political freedom

We also talked about China and its law saying that you can only have one child. They created the law because it was overpopulated by a large amount. They believed that if they created the law of only one child per family, then it will decrease the population percentage. And it worked. The population percentage decreased dramatically. China is still overpopulated, but its population has decreased to make it available to repeal the law now. Now in China, they can have more than one child unlike previous years where they either had to not have more than one child or if they did, put them up for adoption so that they can have better life opportunities in places like the U.S or Canada. India, however, is becoming overpopulated because they didn't have the law that CHina had. They kept on allowing families to have 4-5 children. Now it's becoming a problem and Mr. Schick said that before we go to college, India will be the country with the highest population. It will overtake China. We will have a test on everything that we've covered and more around Friday, October 25.
