It is difficult to accurately determine the proportion of the population that is atheist because survey definitions, and even real life definitions, are often unclear. Some people are unsure of the existance of God, making them [[agnostic]], but they are sometimes counted as atheists. Furthermore, surveys containing an option for "no religion" are not necessarily identifying atheists. Individuals may believe in some form of god but not subscribe to any particular religion. | It is difficult to accurately determine the proportion of the population that is atheist because survey definitions, and even real life definitions, are often unclear.
