It is possible to estimate an optimal human population size based on various criteria and assumptions. Around two thirds of the estimates fall in the range of 4 billion to 16 billion persons, and the median value is about 10 billion1,2 –the size that the UN expects in 2055 under its median variant projection.
Why does the population increase at a fast rate?
This rapid growth increase was mainly caused by a decreasing death rate (more rapidly than birth rate), and particularly an increase in average human age. By 2000 the population counted 6 billion heads, however, population growth (doubling time) started to decline after 1965 because of decreasing birth rates.

What is the formula for calculating population growth?
Formula for Population Change. The standard formula for calculating growth rate is: Gr= N / t. Here, Gr is the growth rate expressed as a number of individuals. N is the total change in population size for the entire time period, also expressed as a number of individuals. t is time, usually expressed in number of years.

Part 2 of 2: Calculating Average Growth Rate Over Regular Time Intervals Organize your data in a table. This isn’t absolutely necessary, but it’s useful, as it allows you to visualize your given data as a range of values over a Use a growth rate equation which takes into account the number of time intervals in your data. Isolate the “growth rate” variable. Solve for your growth rate.
