Back in the Southern Baptist Convention's boom years, from the 1960s to 2010, the experts charting baptism statistics divided "children" into three groups -- starting with those under age 6.
Behind the scenes, there were discussions about when children reached the "age of accountability" and could make mature professions of faith in Jesus Christ, leading to "believer's baptism" by full immersion in water. As with many other doctrinal issues, this was settled by local-church leaders. The same was true when adults asked to be rebaptized, for various reasons.
"At the end of the day, when someone says they've decided to give their life to Christ, the local church is going to let them symbolize that by being baptized," noted Scott McConnell, executive director of Lifeway Research. "That's what Baptists do. That's who we are."
Obviously, Baptists pay close attention to baptism statistics, along with trends with church attendance and membership. In a new report, Lifeway dug into Southern Baptist Convention Annual Church Profile numbers for 2025 and reported that baptisms rose for the fifth consecutive year.
Baptist leaders quickly noted another current trend -- adults 30 and older represented 33% of all baptisms. That was higher than the baptism of those 12-17 (25%), children before age 12 (22%) and young adults between 18-29 (20%). In the past, it was common for the baptism of minors to be two-thirds of the total, noted McConnell, reached by telephone.
The "seismic development" in these numbers is the consistently rising number of conversions among Americans over age 18, noted the Rev. R. Albert Mohler, Jr., president of Southern Baptist Theological Seminary in Louisville, Kentucky.
