The assessment of fertility rates is an absolute necessity for the understanding of the growth rate of the Ottoman population. It is generally assumed that during the first thirtv years of the nineteenth century the Ottoman population decreased, beginning to increase again after 1850. This assumption is one-sided and only partly true, for it ignores the differences in growth rates between Muslim and non-Muslim groups. The non-Muslim population actually grew at a fairly fast rate after the 1830s—probably 2 percent annually; the Muslim population declined or remained the same in number. There are indications, however, that fertility rates among the Muslims began to increase after 1850. The causes of the disproportionate fertility rates among the two groups are to be found in the special economic and social conditions which favored non-Muslims and penalized the Muslims, especially Turks. Male Turks spent their peak reproductive years in military service and were unable to marry and settle down to take advantage of economic opportunities. Then, when in the nineteenth century the Ottoman state was exposed to the influence of the European capitalist economy and to intensified internal and international trade, several non-Muslim groups became the early recipients of the economic benefits—and the promoters as well—of the new economic system.
