概要	Religious attendance measurement addresses a deceptively simple question - how often do people actually attend religious services? - and the systematic bias that plagues the obvious answer. Hadaway, Marler, and Chaves's 1993 American Sociological Review article 'What the Polls Don't Show' demonstrated that Americans substantially overreport church attendance: when they compared the roughly 40 percent weekly attendance that polls report with actual head counts in congregations, they found real attendance was far lower, around 20 percent for Protestants and 28 percent for Catholics. The method therefore centers on validating self-reports against independent benchmarks - direct counts and, in later work, time-use diaries - and on correcting survey estimates for the overreporting that arises because attendance is socially desirable and respondents answer with an identity rather than a tally.	Secularization index modeling measures the decline of religion in modern societies and models its dynamics across generations. It combines two tasks: building defensible indices of religiosity from survey items on belief, belonging, and practice, and decomposing observed change into age, period, and cohort components to determine whether religion is fading as individuals age, as eras shift, or as each successive birth cohort enters life less religious than the last. Steve Bruce's God is Dead (2002) restated the classic secularization thesis that modernization corrodes religious authority and participation, while David Voas's 2009 analysis of European data showed that decline is overwhelmingly a cohort phenomenon and introduced the idea of 'fuzzy fidelity' - a large middle that is neither firmly religious nor wholly secular - that swells and then shrinks as societies move through the secular transition.
