Our Human population
There are 7.1 billion people in this world, and as you read this, 21 babies are being added to that count. It might seem like a lot, but don't forget people are dying every minute too. How does the human population grow? Due to the fact that there are many more births than deaths, it causes the human population to grow. And it is predicted that the human population will keep growing.

First let’s understand , how does a population grow? Well to know the population growth we need to know the per capita rate (r)which means, the ratio of surviving offspring an individual has over the individual’s death, and the population size(N)
|
A tool used to predict the population’s future growth is known as an age structure.The age structure of a population is the number of individuals in a specific age group. This age structure shows us that many individuals will live from about ages 0-10) as the grow older you can see the number of individuals that are alive starts decreasing. For example look at age 80, very few people will live to that age. And this age structure is designed for you to see the male and female count.
Another thing that affects our population growth is population momentum. What’s population momentum you might ask. Population momentum is when there’s an abundance of resources and childbearing females it causes the population to grow greatly very fast.

As you can see our human population consists of many people....
