WASHINGTON, D.C. — Weekly church attendance has declined among U.S. Catholics in the past decade, while it has remained steady among Protestants.
From 2014 to 2017, an average of 39% of Catholics reported attending church in the past seven days. This is down from an average of 45% from 2005 to 2008 and represents a steep decline from 75% in 1955.
By contrast, the 45% of Protestants who reported attending church weekly from 2014 to 2017 is essentially unchanged from a decade ago and is largely consistent with the long-term trend.
… Currently, the rate of weekly church attendance among Protestants and Catholics is similar at most age levels. One exception is among those aged 21 to 29, with Protestants (36%) more likely than Catholics (25%) to say they have attended in the past seven days.
Protestants’ Pie Is Shrinking Faster Than Catholics’
While attracting parishioners to weekly services is vital to the maintenance of the Catholic Church and Protestant denominations alike, so too is maintaining a large base of Americans identifying with each faith group.
Although the rate at which Protestants attend church has held firm over the past six decades, the percentage of Americans identifying as Protestant has declined sharply, from 71% in 1955 to 47% in the mid-2010s. Since 1999, Gallup’s definition of Protestants has included those using the generic term “Christian” as well as those calling themselves Protestant or naming a specific Protestant faith.
By contrast, while the Catholic Church has suffered declining attendance in the U.S., the overall percentage of Catholics has held fairly steady — largely because of the growth of the U.S. Hispanic population. Twenty-two percent of U.S. adults today identify as Catholic, compared with 24% in 1955.
A troubling sign for both religions is that younger adults, particularly those aged 21 to 29, are less likely than older adults to identify as either Protestant or Catholic. This is partly because more young people identify as “other” or with other non-Christian religions, but mostly because of the large proportion — 33% — identifying with no religion.
…Although weekly attendance among Protestants has been stable, the proportion of adults identifying as Protestants has shrunk considerably over the past half-century. And that trend will continue as older Americans are replaced by a far less Protestant-identifying younger generation.
All of this comes amid a broader trend of more Americans opting out of formal religion or being raised without it altogether. In 2016, Gallup found one in five Americans professing no religious identity, up from as little as 2% just over 60 years ago.
