According to International Middle east studies, Stanford J. Shaw (1978), Ottomans did develop a reasonably efficient system of counting the empire’s population only a quarter century after census procedures were introduced in United States, Great Britain and France. After 1831, the census takers tried to determine between Muslim and non-Muslim population, these were registered as below sixteen, between sixteen and forty and above forty years. By this period Christian and Jewish males were not subject to military service. Ottoman rule lasted until World War I when Istanbul was occupied by the allied troops. After years of struggle led by Ataturk against the occupying forces, the Republic of Turkey was born in the year 1923 and the capital was moved from Istanbul to Ankara province. But later Istanbul has continued to expand dramatically with migration.
