Today I took a test and I didn't do well even though I studied. I guess I probably made stupid mistakes like I always do. After that we talked about different populations and stuff like that. We learned that there is 7.6 billion people in the world and there is still people being born and dying which makes that number fluctuates often. We also learned that in some countries you had to pay money to the government if you. wanted more kids than only just having one. Also, I learned that 90% of the Earths population growth is because of the countries such as Africa, South and East Asia, and Latin America. Finally, there is a lot of people who immigrate to. America that cause a bigger population.
Population
Today we talked more about the population of the whole world. First we talked about the different types of rate such as crude birth rate, crude death rate, rate of natural increase, and Net Migration Rate. Crude birth rate is number of births per 1000 of the population which is the opposite of crude death rate. We also learned that the rate of the natural increase is produced by subtracting the death rate from the birth rate and this gives us the annual natural g rowth rate in percentage form for country or region. we also learned about Net migration net which is the difference between the number of persons entering and leaving a country during a year. Finally, we learned that an excess of people leaving the country is net emigration and the people entering is net immigration.
