(Joshua Paladino, Liberty Headlines) Americans have become less religious in the last 15 years, with a decline in the number of people who identify as Protestants and an increase of people who have no religious affiliation.

The survey, conducted by Langer Research Associates, found that Americans who identify as Protestant dropped from 50 percent in 2003 to 36 percent in 2017, ABC News reported.

In the same time period, Americans without a religious affiliation have almost doubled, rising from 12 percent to 21 percent.

Of the Americans without a religious affiliation, 3 percent identify as atheistic, 3 percent identify as agnostic, and the remaining 15 percent said they do not have a religion.


Langer Research Associates polled more than 174,000 Americans during the 15-year period.

Protestantism still remains the largest Christian segment in the United States, though it has dropped from 83 percent of adults to 72 percent.

Other forms of Christianity have strengthened or remained steady.

Americans who identify as Catholic, the second largest Christian group in the United States, have stayed at 22 percent since 2003.

Identifications with smaller Christian-based denominations, including Jehovah Witnesses, Mormons, and Greek or Russian Orthodox, has risen slightly from 11 percent to 14 percent.

The decrease in religious affiliation has occurred primarily among political liberals and young adults.

The number of political liberals who identify as Protestant decreased from 40 percent to 25 percent.

The shift accompanied a 16 percent increase in those who have no religion at all.

Political liberals composed the bulk of the “no religion” category at 35 percent, whereas only 12 percent of political conservatives said they did not have a religion.

Political conservatives have become less religious as well, with 12 percent identifying as having no religion in 2017 — up from 8 percent in 2003.

Young adults aged 18 to 29 years old tied political liberals for the least-religious group in the United States, with 35 percent saying they had no religious affiliation.

The number of Evangelical white protestants, who are considered a major Republican voting block, dropped from 21 percent of the population to 13 percent.

Among adults who identify as Evangelical Protestants, nearly half are Republicans, about one-third are independents, and less than 15 percent are Democrats.
