When calculating population growth, you will need to know the initial population, the rate of growth, and the number of years. The formula to calculate population growth is:
The result will be the estimated population after the specified number of years, considering the provided growth rate. Keep in mind that this is an approximation and actual population growth can be influenced by many unpredictable factors.
Our population growth calculator is very simple and easy to use. Follow these steps:
Let's say we want to estimate the population growth over 10 years, starting with an initial population of 8.2 billion and assuming a growth rate of 1.1% each year. First, we enter 8.2 billion into the initial population field, then input 1.1 as the growth rate, and finally, enter 10 as the number of years.
We can now hit calculate and get 8.528 billion people as our estimated population after 10 years.
The USA believes we reached 8 billion people on Earth on November 15th, 2022. This day is often called the day of eight billion.
It is estimated that 100 years ago there were about 2 billion people on Earth. There are issues with tracking population back in the early 1900s, so this figure is an estimate and not confirmed.
According to the United Nations, in 2050 there will be about 9.7 billion people on Earth.
There is no way to tell just how many people Earth can support. There are far too many factors to make an accurate decision, however, there has been an estimate made in the past that Earth can support 13.4 billion people.
With the current population being about 8.2 billion people, 1% of the population would be 82 million people.
