The Barna Group are Evangelical Christians on a mission to expand their church. They are biased, their information is inflated and misleading, they have been accused of fraud. 62%, according to Pew Research identify as Christians. When questioned further, some people called themselves Christians simply because they were nice people and associated being nice with being Christian, often these people never attended church, or prayed or any other practice.
So, your information is bogus.
"A 2009 Barna Group study reported similar trends, noting that 35% of liberals attended a religious service in the past week and 76% prayed to God outside of services, compared to higher rates among conservatives (62% and 91%, respectively).
More recent data from a 2023 Gallup survey suggests that only 16% of white liberals are highly religious (defined as attending services weekly and considering religion important), compared to 52% of white conservatives. Black liberals, however, show higher religiosity, with about 23% of white Democrats (a proxy for liberals) being highly religious, though this includes moderate and conservative-leaning Democrats.
A 2025 X post claimed 62% of liberals say they have no religion, but this lacks corroboration from primary sources and may exaggerate the trend.
In summary, roughly 40-60% of liberals identify as religious, but active participation (e.g., regular service attendance or strong belief in God) is lower, likely around 20-35%, with variations by race and definition. For precise figures, check Pew Research Center’s Religious Landscape Study or Gallup’s religion polls."
You are wright that different groups may exaggerate numbers to their favour.
You still have religious liberals.
Feel free to provide your estimates.
Question still stands.
If we see problems, associating them with religion, should not be just knee jerk reaction, it should be substantiated.
So please, elaborated, on how you would link religiuos beliefs with problems that are of concern of yours.
