The map shows the results of an Eurobarometer poll conducted in 2005. This is the percentage of people in each country who answered "I don't believe there is any sort of spirit, God or life force". Grey countries were not included in the poll. See also Image:Europe belief in god.png for percentage of people answering "I believe there is a God" in the same pool.
