Calculate Log Growth Rate





Formula

To calculate the log growth rate:

\[ r = \frac{\ln(P1 / P0)}{t} \]

Where:

What is Log Growth Rate?

Log growth rate is a measure of the rate at which a population grows exponentially over time. It is a common concept in biology, demography, and other fields where understanding the dynamics of population growth is important. The log growth rate is based on the natural logarithm and provides a way to quantify the growth in a way that can be easily compared across different populations or time periods.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ r = \frac{\ln(200 / 100)}{5} = \frac{\ln(2)}{5} \approx 0.1386 \]

The Log Growth Rate is approximately 0.1386 per year.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ r = \frac{\ln(1000 / 500)}{10} = \frac{\ln(2)}{10} \approx 0.0693 \]

The Log Growth Rate is approximately 0.0693 per year.
