Population Prediction Calculator

Formula

The formula to calculate the Predicted Population Size (P) is:

\[ P = P_0 \times (1 + r)^t \]

Where:

\(P\) is the predicted population size
\(P_0\) is the initial population size
\(r\) is the growth rate (expressed as a decimal)
\(t\) is the number of years

What is Population Prediction?

Population prediction is the process of estimating the future size of a population based on current data and trends. This is often done using mathematical models that take into account factors such as birth rates, death rates, immigration, and emigration. Predicting population size is important for planning in areas such as urban development, resource management, and public policy.

Example Calculation

Let's assume the following values:

Initial Population Size (P₀) = 1000
Growth Rate (r) = 0.02
Number of Years (t) = 10

Using the formula:

\[ P = 1000 \times (1 + 0.02)^{10} = 1000 \times 1.219 = 1219 \]

The Predicted Population Size is 1219.
