POPULATION
The world has many people living in it. There is currently 7.6 billion people. That is 2.5 per second, 8377 per hour, 200,000 per day and 73 million per year. 90% of the population growth in the world is from developing countries such as Africa, and mid eastern countries. In the U.S.A. the average lifespan for a man is 77 years compared to a female which is 81. Some people migrate to the U.S.A. for many reasons. Some push factors are civil war and lack of jobs. Some pull factors are jobs, food, opportunity and most of all, freedom. The average amount of children to women is 2.1. This makes sense because both children replace the mom and dad when they die and the cycle continues. In China, population used to be a problem so if you had more than one child you had to pay for it.
