Frequency of cohabitation among 13,703 adults from the British Social Attitudes dataset for 1985-2005 peaked at around 26-30 years of age, and increased significantly over the period of study. Cohabitation frequency was compared between those of no religious affiliation and Christian affiliates who (a) attended church at least once a month, (b) attended church, but less than once a month, and (c) never attended church. Active Christians were 3.2 times less likely to cohabit than non-affiliates, and rates of cohabitation have remained stable over time in this group. Christian affiliates who never attended church were 1.2 times less likely to cohabit than non-affiliates, suggesting that even affiliation without attendance may indicate greater affinity to Christian moral attitudes compared with non-affiliates
