In a 2009 Gallup International survey, 41.6%[123] of American citizens said that they attended a church, synagogue, or mosque once a week or almost every week. This percentage is higher than other surveyed Western countries.[124][125] Church attendance varies considerably by state and region. The figures, updated to 2014, ranged from 51% in Utah to 17% in Vermont.
