Crude density, also known as arithmetic density, is the most commonly
used measure of population density. It is expressed as the number of
people divided by the total area. India, for example, has an average
density of 324 persons per square kilometer, as per the latest census of
2001. Crude or arithmetic density can be worked out separately for
rural and urban areas. Being an average figure, crude density suffers
from a serious limitation. Crude density is one dimensional and tells
little about the opportunities land. Since it takes into account the
total surface area, crude density presents a very misleading picture,
and particularly when there is a substantial variation in density within
a region.Egypt, for instance, with a population of 1004.9 thousand
square kilometers, presents a crude density of 72 persons per square
kilometer. However, it has been estimated that nearly 98 per cent of
Egypt’s population occupies less than 5 per cent of the country’s total
area in the nile valley and delta where density is more than 1,000
person per square kilometer while the rest of the country is desert.
Geographers have, therefore, devised other measures of density by
modifying numerator or both to illustrate the actual variation in the
density of human occupation within a region settlement geography buy now.
