As I indicated, numbers in the Anglican church are falling, hence the perceived decline in the number of baptisms, but there are far more attending the evangelical churches than ever before.
This report is from 2012.
//As the number of people who are actively committed to the Church of England falls, the proportion of churchgoers who are serious about their faith—and its implications for private and public life—is growing. Peter Brierley, a collector of statistics on faith in Britain, reckons that 40% of Anglicans attend evangelical parishes these days, up from 26% in 1989.//
