Demographics of atheism
Encyclopedia
The demographics of atheism are difficult to quantify. Different people interpret "atheist" and related terms differently, and it can be hard to draw boundaries between atheism, non-religious beliefs, and non-theistic religious and spiritual beliefs. Furthermore, atheists may not report themselves as such, to prevent suffering from social stigma

There is a great deal of room for debate as to the accuracy of any method of estimation, as the opportunity for misreporting (intentionally or not) a category of people without an organizational structure is high. Also, many surveys on religious identification ask people to identify themselves as "agnostics

Some politically motivated organizations that report or gather population statistics may, intentionally or unintentionally, misrepresent atheists. Survey designs may bias results due to the nature of elements such as the wording of questions and the available response options.

. Statistics are generally collected on the assumption that religion is a categorical variable. Instruments have been designed to measure attitudes toward religion, including one that was used by L. L. Thurstone. This may be a particularly important consideration among people who have neutral attitudes, as it is more likely prevailing social norms will influence the responses of such people on survey questions which effectively force respondents to categorize themselves either as belonging to a particular religion or belonging to no religion. A negative perception of atheists and pressure from family and peers may also cause some atheists to disassociate themselves from atheism. Misunderstanding of the term may also be a reason some label themselves differently.

However, the same study also reported that, “The researchers also found acceptance or rejection of atheists is related not only to personal religiosity, but also to one’s exposure to diversity, education and political orientation—with more educated, East and West Coast Americans more accepting of atheists than their Midwestern counterparts.”

The highest occurrence of "nones", according to the 2008 ARIS report, reside in Vermont, with 34% surveyed.

The latest statistics show that a lack of religious identity increased in every US state between 1990 and 2008. However less than 2% of the U.S. population describes itself as atheist.

Atheism is more prevalent in Canada than in the United States, with 19–30% of the population holding an atheistic or agnostic viewpoint. The 2001 Canadian Census states that 16.2% of the population holds no religious affiliation, though exact statistics on atheism are not recorded. In urban centers this figure can be substantially higher; the 2001 census indicated that 42.2% of residents in Vancouver hold "no religious affiliation." A recent survey in 2008 found that 23% of Canadians said they did not believe in a god.

Separation of church and state is guaranteed by Article 130 of the Mexican Constitution, which also designates religious leaders as ineligible for public office, while the majority of the population identifies as Roman Catholic (89%).

Although the demographics of atheism and irreligion in Mexico is hard to measure because many atheists are officially counted as Catholic, almost three million people in the 2000 National Census reported having no religion. Recent surveys have shown that only around 3% of Catholics attend church daily and, according to INEGI, the number of atheists grows annually by 5.2%, while the number of Catholics grows by 1.7%.

Population attributes of atheists in the US

Overall, U.S. Americans who profess no religion or self-identify as atheist or agnostic are more likely to be white, non-Hispanic, or Asian and less likely to be African American or Hispanic, as compared to the general adult population in U.S.

In the U.S., 55 percent of atheists are under age 35, while 30 percent are 50 and over (compared to 37 percent of the total population). As a group agnostics are older than atheists, though still younger than the general population. Comparing this 2001 data with the 1990 National Survey of Religious Identification (NSRI) provides evidence of a trend towards secularization among the younger American population.

In the US men are more likely to be atheists than women, and also rate lower on various other measures of religiousity such as frequency of prayer.

In "The New Criminology", Max D. Schlapp and Edward E. Smith say that two generations of statisticians found that the ratio of convicts without religious training is about 1/10 of 1%.

"The analyses of the National Longitudinal Study of Adolescent Health (Study 1) and the General Social Surveys (Study 2) show that adolescent and adult intelligence significantly increases adult liberalism, atheism, and men's (but not women's) value on sexual exclusivity."

South America

Irreligion in South America is not decreasing over 30 years straight, and it had a growing status in all countries in the first decade of the 21st century. In Brazil, it rose from about 4% in the end of 20th century to circa 8% in the most recent reliable census and recent estimates put it in 10–14% of the population, being the 2nd largest religious group after Christianity. According to recent researches, Brazilians who profess no religion or self-identify as atheist or agnostic are more likely to be white Brazilian
