### What is the difference between arithmetic density and physiological density?

The arithmetic density of a population is the total number of
people in proportion to the area of land (land size)
The physiological density of a population is the total
population in proportion to the area of arable land.
Therefore, the arithmetic density of a population is always
lower than the physiological density, since a land's arable portion
can only be a subset of it's full size.
Arithmetic = (Population/Full size)
Physiological = (Population/Arable zones)

### How do you measure the population density of individuals living in a defined space?

Divide the total number of individuals by the total number of
whichever units of area you are using.
For example, in 2011 there were 3,063,500 people living in
Wales. The total area of Wales is 20,779 km².
3,063,500 / 20,779 = 147.43250397
Therefore the population density of Wales in 2011 was 147 per
km² (rounded figure).
