Participating groups counted 54.5% of residents as adherents in 2010, +0.7 points on 1980; Mississippi rose most (+12.1 points)
Largest fall: Rhode Island (-22.5 points). Which groups took part changed between waves (most historically Black denominations did not report in 2000), so a share can move because a group joined or left; the 2020 census is not harmonised with these waves.
