factor in their lives, which was the lowest percentage in the world amongst countries with significant Muslim populations. Another survey conducted by Gallup Global Reports 2010 shows that religion plays a role to 39% of Albanians, and lists Albania as the thirteenth least religious country in the world. Also in Albania the majority of the males are not circumcised (as demanded by Islamic custom). A medical study from 2008 in Tirana on the relationship between religious observance and acute coronary syndrome found out that 67% of Muslims and 55% of Christians were completely religiously non-observant. The regular attendance of religious institutions (at least once every 2 weeks) was low in both denominations (6% in Muslims and 9% in Christians), and weekly attendance was very low (2% and 1%, respectively). Frequent praying (at least 2 to 3 times per week) was higher in Christians (29%) than in Muslims (17%) Praying several times daily (as required of devout Muslims) was rare (2% in Muslims and 3% in Christians). Regular fasting during Ramadan or Lent was similarly low in Muslims and Christians (5% and 6%, respectively). Generally Christians in the study were more observant than Muslims (26% vs 17%). A 2015 study on the Albanian youth aged 16–27 found that total of 80 percent of young people in Albania are not religion practitioners and practise their religion only during the main religious holidays and festivities. Specifically 23 percent of the respondents never practised their religion, while 61 percent practised it only in religious holidays. From the rest, 11 percent practised it 1–2 times a week, while 5 percent practised it every day. In the European Values Survey in 2008, Albania had the highest unbelief in life after death among all other countries, with 74.3% not believing in it. According to a WIN/Gallup International study in 2016 about the beliefs of the Albanians: 80% believed there's God 40% believed in life after death 57% believed that people have a soul 40% believed in hell 42% believed in heaven Estimates of the 2018 published Swiss Metadatabase of Religious Affiliation (SMRE) assume for the period 2000 (1996–2005) 8% Catholics, 15% Orthodox, 65.9% Muslims and 10.9% people with no religious affiliation. For the period 2010 (2006–2015) the SMRE estimates 8.7% Catholics, 9.1% Orthodox, 52.5% Muslim and 29.5% people with no religious affiliation.
