ABSTRACT
Population is counted by the census. It is also advisable to rely on a census for certain aspects of population classification, e.g., distribution of nomads, division between village and town, distribution by occupation, etc. The main difficulty encountered in any research on the population of the Middle East is the total absence of any such census in some countries, and its confused results in others. There are three reasons why some countries of the Middle East have never carried out a census:
the structure of the population;
lack of modern administrative method;
political factors.
