Pomak Muslims mainly live around the Rhodope Mountains, especially in the province Smolyan and the municipalities of Satovcha, Yakoruda, Belitsa, Garmen, Gotse Delchev, Ardino, Krumovgrad, Kirkovo and Velingrad. A large part of the population in those areas did not respond to the census questions which makes it difficult to calculate the exact number of Pomaks. In the municipality of Dospat for example, only 4746 people out of 9116 answered the question on their religion and in the municipality of Satovcha only 9562 out of 15444 people did so. Pomaks live mostly in rural areas and their fertility rates are among the lowest in Bulgaria.
