In 2011, a Pew Research Center population estimate in a global study based on growth rates put the percentage of Muslims in Albania at 82.1% (estimated number 2,601,000)[104] However, a Gallup poll gave percentages of religious affiliations with only 43% Muslim, 19% Eastern Orthodox, 15% Catholic and 23% atheist or nonreligious.[105][when?] In the 2011 census the declared religious affiliation of the population was: 56.70% (1,587,608) Sunni Muslims, 2.09% (58,628) Bektashis, 10.03% (280,921) Catholics, 6.75% (188,992) Orthodox, 0.14% (3,797) Evangelists, 0.07% (1,919) other Christians, 5.49% (153,630) believers without denomination, 2.05% (69,995) Atheists, 13.79% (386,024) undeclared.[3] Controversies surrounded the Albanian census (2011) over whether a religious affiliation option should be part of the count as people like some intellectuals in Albania feared that the results may make Albania appear "too Muslim" to Europe.[106] From previous pre-communist highs of 69.3% (1937) and 72% (1947) the official census of 2011 was the first to count religious affiliation after an absence of many decades that showed the Albanian Muslim population to have deceased to 56.70%.[5] The Muslim community of Albania objected to having the generic Muslim option split according to internal differentiation into categories such as Bektashi.[6][106] The census results overall have been criticized by the Muslim community of Albania and they have estimated the number of all Muslims in Albania to be 70%.[6] Owing to the large number of people in Albania not having declared a religion the census figures leave scope for other explanations and analyses of what is the actual religious composition of Albania.[6]
