A mathematical formula is then used to estimate population size.
Population Estimate=((Total number captured)×(Number marked))/(Total number captured with marked)
To calculate the population density, you will divide the population by the size of the area.
Thus, Population Density = (Number of organisms)/(Land Area)
The unit of land area should be square kilometers.
You can use square meters if you are finding the density of a smallish space.
