Some Americans may be more inclined to follow the faith of their parents or grandparents, according to a new study by researchers at the University of California, San Diego.

The study, which is published online in the Journal of Religion and Health, found that the proportion of Americans who are religiously unaffiliated is at a record high in the U.S.

A new survey by the Pew Research Center found that 47 percent of Americans identify as “nones” or “nothing in particular” when it comes to their religion.

More than half (53 percent) of people in the country say they believe in at least one god.

That is up from 43 percent in 2012, but that’s still lower than the 71 percent of people who said the same in 2009.

In addition, only 19 percent of respondents in the study say they’re not religious, compared with 31 percent in 2011 and 35 percent in 2010.

The rest are either agnostic or nonreligious.

Pew found that Americans are more likely to be religious in the absence of an official religious affiliation.

While the share of Americans identifying as atheist or agnostic has decreased since 2009, the percentage of people identifying as neither religious nor atheist has increased.

When it comes time to fill out a religious questionnaire, Americans are twice as likely as non-Americans to identify as atheists or agnostics, the survey found.

Still, Pew found that people who identify as neither Christian nor Muslim are still more likely than their religious peers to be religiously unaffnostic.

The survey found that 33 percent of atheists, agnostics and others in that category said they are “not sure” about their religion, compared to 25 percent of those in religious categories.

The percentage of Americans not religious is also up since 2009. 

The study found that in terms of frequency of attendance at religious services, the share reporting attendance at fewer than once a month has been growing over the past decade, and that it is at its highest level in the South and Midwest.

For instance, in 2012 the percentage who attended church once a week or more was up from 11 percent in 2007 to 19 percent in 2017.

Among people who attended religious services regularly in the past 12 months, the number who said they were religiously unafflicted rose to 17 percent from 13 percent.

The survey also found that fewer Americans report being actively involved in their faith today than in the 1960s.

In 2010, 43 percent of the country was religiously unaffmitted, compared.

with 51 percent in 2013 and 61 percent in 2015.

But it appears that there is an opportunity for a growing segment of the population to get involved in religion.

In the Pew survey, 18 percent of nonreligious adults who attend religious services weekly said they would attend a church, synagogue or temple, while 12 percent said they had not attended any religious service in the last year.

In addition to the Pew study, other studies have found that religious people are more involved in the churchgoing and congregational life.

In a 2016 study of U.N. statistics, researchers found that more than half of religious people said they attended church weekly or more.

A recent study of the American public’s attitude toward religion found that only 25 percent believe the Bible is the word of God and just over a third (35 percent) say they are Christian.

Another recent study found an even more pronounced drop in religious involvement from the 1980s to the 2000s, as people became more involved with their churches.
