The percentage of Americans who say they “seldom” or “never” attend religious services (aside from weddings and funerals) has risen modestly in the past decade. Roughly three-in-ten U.S. adults (29%) now say they seldom or never attend worship services, up from 25% in 2003, according to aggregated data from Pew Research Center surveys. The share of people who say they attend services at least once a week has remained relatively steady; 37% say they attend at least weekly today, compared with 39% a decade ago.
