www.cia.gov Facts

Here are some interesting facts from cia.gov about the population of countries around the world.
1. The dominate sex in Brazil is male
This is interesting to me because I would think their would be more women because thats how it has always been, whether its my class ratio or more girls than boys in my family.
2. Afghanistan median age is around 18 years old
This is a representation or the danger and violence going on in that country, it means there are less people who are older, meaning they could have been killed from the violence going on in that country.
3. The smallest population of a country is 54, in the Pitcairn Islands
This is amazing to me because my small town is at least 20 times the population of this, and its a country!!! I start to wonder how they function and continue to thrive as a country.
4. The lowest life expectancy of a country is Chad, with 50.60
This life expectancy shows me that either violence or disease destroys the population of that country, it makes me want to figure out how to solve some of the issues there
5. The birth rate in Angola is 44.20 per 1000 population
This shows me that people have more babies than we do here. When I looked, the TFR is 6.1 children per woman.
Each of these facts I found interesting because they seemed very interesting and important to population as well as population growth. Age, population, birth rate, and life expectancy all play a factor in population, and population growth.
Today in class we discussed total fertility rate. Total fertility rate is the average number of children born per woman. We talked about the number 2.1. We said that in order for population to increase, the total fertility rate had to be over 2.1. Its 2.1 because we have to take into consideration the number of parents that die after the birth of children, so in order to make up for this number, the number is 2.1.
