The Bulgarian Muslims or Muslim Bulgarians (, Bǎlgari-mohamedani, as of recently also Българи-мюсюлмани, Bǎlgari-mjusjulmani, locally called Pomak, ahryan, poganets, marvak, or poturnak) are Bulgarians of the Islamic faith. They are generally thought to be the descendants of the local Slavs who converted to Islam during Ottoman rule. Most scholars have agreed that the Bulgarian Muslims are a "religious group of Bulgarian Slavs who speak Bulgarian as their mother tongue and do not understand Turkish, but whose religion and customs are Islamic". Bulgarian Muslims live mostly in the Rhodopes – Smolyan Province, the southern part of the Pazardzhik and Kardzhali Provinces and the eastern part of the Blagoevgrad Province in Southern Bulgaria. They also live in a group of villages in the Lovech Province in Northern Bulgaria. The name Pomak is pejorative in Bulgarian and is resented by most members of the community, The name adopted and used instead of Pomak is Bulgarian Muslims. Bulgarian Muslims do not represent a homogenous community and have a multitude of ethnic and religious identities. A clear majority of them (127,350 according to the latest census in 2001) declare themselves to be ethnic Bulgarians of Islamic faith. However, a significant percentage, in particular in the Central and Eastern Rhodopes (the Smolyan and Kardzhali Province) are strongly religious and have preserved the Muslim name system, customs and clothing, the Smolyan Province, which is largely populated by Bulgarian Muslims (approximately 117,000 or 71% of the population according to the Ministry of Interior in 1989), According to the 2001 census, 43 municipalities out of 262 have a Muslim majority. There were five municipalities with a Muslim population over 90 percent: Chernoochene (96.8 percent) has the highest share of Muslims, followed by Venets (95.9 percent), Satovcha (91.3 percent), Ruen (90.9 percent) and Kaolinovo (90.0 percent)(122,806 or 87.7%) and that only 58,758 people or 41.9% of the population of the province declared to profess Islam in 2001. Muslims in Bulgaria have slightly better demographic indicators compared to the Orthodox Christians in Bulgaria. The reason for this difference is mostly because of ethnicity most Muslims in Bulgaria have different reproductive traditions and they have a younger age structure compared to the ethnic Bulgarians which leads to higher fertility and birth rates. In provinces with large Muslim concentrations, birth rates are a little bit higher while death rates are lower than the country average. For example: Bulgaria had a total birth rate
