When total population is viewed in
relation to the amount of land under cultivation in a region in a region, we
get physiological density or nutritional density. This is a more meaningful
index of population density in any area. In the case of Egypt, while the crude
density is only 72, physiological density works out to be nearly 2,500 persons
per square kilometer of cultivable land. The measure is appropriate for a
situation where agriculture is the mainstay of population. But it is also true
that not all the people in a region or country are dependent on agriculture latestworld geography buy now
