Religious and Secular Trends

The United States is experiencing notable shifts in religion and secular life that affect communities, public services, and policy debates. Fewer than half of Americans now say religion is important in daily life, and a record share identify as religiously unaffiliated—trends that are reshaping civic and social institutions (America’s Religious Decline Creates New Battleground).

The data at a glance

Recent studies show about 29% of adults are unaffiliated while Christian identification has fallen, and industry observers project widespread church closures this year—figures that reflect both long-term generational replacement and shorter-term shifts that may be plateauing (America’s Religious Decline Creates New Battleground).

Who is changing and how

Young adults—especially Gen Z women—are leaving organized religion at higher rates, while belief in traditional forms of God and routine religious practices have declined; at the same time many people retain individualized spiritual or syncretic beliefs rather than formal affiliation (America’s Religious Decline Creates New Battleground).

Why it matters for government

Shifts in affiliation and practice affect zoning, social-service delivery, education, and healthcare planning where faith-based institutions have been partners; understanding these trends helps policymakers design services and regulations that reflect a more religiously diverse and often less institutionally religious population (America’s Religious Decline Creates New Battleground).
