Faithlessness Is the New Black

The fastest growing religion in the US:

None.

From 1990 to 2001, people who have no religion/are atheists/are agnostic grew 6.6 percent, from 8.4 to 15.0 percent of all Americans. The number of these people increased 105.7 percent.

This is according to the American Religious Identification Survey performed by the Graduate Center at the City University of New York. For the survey people were asked only: "What is your religion, if any?"

The survey found that "the greatest increase in absolute as well as in percentage terms has been among those adults who do not subscribe to any religious identification; their number has more than doubled from 14.3 million in 1990 to 29.4 million in 2001."

Note: This post cites ARIS (despite my desire for more current data) because "statistics on religious adherence are difficult to gather and often contradictory; statistics for the change of religious adherence are even more so, requiring multiple surveys separated by many years using the same data gathering rules. This has only been achieved in rare cases, and then only for a particular country, such as the American Religious Identification Survey in the USA." (Wikipedia)

Which is to say (write): I used ARIS because it's the only reliable source available.

Mixx it!
