U.S. Religious Groups & Religious Maps

What is the difference between a cult and a religion? 100 years!
About 1,000 letters arrive in Jerusalem every year addressed to God!

In a recent Gallup poll, 63% of Americans said they believed that religion could solve the vast majority of today's social problems, a percentage which has remained stable for 30 years. Over 70% of Americans are members of a church or synagogue, and 40% attend regularly, compared with only 12% in Britain.

Only in 1954 was the phrase "under God" added to the Pledge of Allegiance and in 1955, "In God We Trust" was added to U.S. paper money.

According to Gallup polls, only 10% of the USA population (30 million, which is larger than the total number of Roman Catholics and Baptists combined) say they hold a secular, scientific evolutionist view of the world, while 44% believe in strict biblical creationism. Three times as many people believe in the Virgin birth than in evolution. In the United States a Gallup poll conducted in 2008 found that only 14% of people agreed with the proposition that “humans developed over millions of years”, up from 9% in 1982. Acceptance of evolution varies around the world, with the most ardent believers being in Iceland, Denmark, and Sweden (see chart to the right). Read a relevant article

About 2,000 different religious denominations and cults are found in the United States! The United States supports more than 200 Christian TV channels and 1,500 Christian radio stations. The USA is three times more religious today than at the start of the republic, measured by church attendance. In other rich countries, including Canada, church attendance and religious beliefs have declined. Unique to the USA, many public policy issues are framed in religious terms: sexual activities in their many forms, abortion, alcoholism, stem-cell research, homosexuality, and divorce.

Data for the maps below come from Churches and Church Membership in the United States, 1990. Roper Center for Public Opinion Research, University of Connecticut. Angela Laufenberg, a geography major at UWEC, used these electronic data to make the maps, which were presented at the annual meeting of the Association of American Geographers in Chicago, IL. Here are the general church patterns:
