outlier highly developed a high level of religiosity and wealth no religion wealth
Until the 1990s, the country was an outlier among highly developed countries, having a high level of religiosity and wealth, although this has lessened, with "sharp declines in church attendance, confidence in organized religion and religious identification..." since then. Around 30-33% of Americans describe themselves as having no religion, with some retaining some beliefs and practices.
Membership in a house of worship fell from 70% in 1999 to 47% in 2020.
