According to the most recent Eurobarometer Poll 2005,[10]

23% of Swedish citizens responded that "they believe there is a God".
53% answered that "they believe there is some sort of spirit or life force".
23% answered that "they do not believe there is any sort of spirit, God, or life force".

Several studies have found Sweden to be one of the most atheist countries in the world. According to Davie (1999), 80% of Swedes do not believe in God.[12] In the Eurostat survey, 23% of Swedish citizens responded that "they believe there is a God", whereas 53% answered that "they believe there is some sort of spirit or life force" and 23% that "they do not believe there is any sort of spirit, God, or life force". This, according to the survey, would make Swedes the third least religious people in the 27-member European Union, after Estonia and the Czech Republic. In 2001, the Czech Statistical Office provided census information on the ten million people in the Czech Republic. 59% had no religion, 32.2% were religious, and 8.8% did not answer.[13]
