sir82,
The data seem to confirm your comments. The following information is based on the same Pew Research Center report from 2015, and it shows that immigrants are as likely to be secular or atheist as those in this country, are selecting non-xtian religions at a higher rate, and overall xtianity is decreasing as a choice for immigrants since 2000. The final 'telling' stat from the report is that 15% of the respondents were first gen immigrants; assuming that is representative of the US, the % of J-dubs who are 1st gen immigrants is considerably above the norm, as are those who are choosing x-tianity.
Without 1st gen immigrants the DarkTower would be in serious US decline it seems. But we already knew that.
MAY 19, 201 GROWING SHARE OF U.S. IMMIGRANTS HAVE NO RELIGIOUS AFFILIATION
BY CARYLE MURPHY
"Immigrants to the U.S. are increasingly identifying themselves as religiously unaffiliated, that is, atheist, agnostic or having “no religion in particular,” according to a new Pew Research Center study of America’s religious composition. Indeed, recent immigrants (those who have arrived since 2000) are as likely to have no religious affiliation as the country’s overall adult population.
Our 2014 Religious Landscape Study, a follow-up to the center’s first Religious Landscape Study in 2007, found that one-in-five immigrants said they did not belong to any religion – an increase of 4 percentage points since 2007, when 16% said they did not associate with any faith tradition.
The new survey also found that the share of Christian immigrants has slipped somewhat in the same period, moving from 75% to 68%. That too is in line with trends in the general population, where the share that is Christian has declined.
There also has been growth in the percentage of immigrants who are adherents of non-Christian faiths, rising from 8% to 12% in the past seven years, the new study found. Some groups have seen significant increases. For instance, Muslims now account for 4% of foreign-born residents in this country, up from 2% in 2007.
Roughly one-in-seven (15%) of the more than 35,000 participants in the new survey were born outside the U.S."
