Recent research studies of religion

Half of children with two religious parents reject church
"Religious belief is declining faster than attendance at services in the UK, according to a new study funded by the ESRC which found that parents' beliefs, practices and affiliations have the biggest impact on children."

"It found that when it comes to religion, parents are the most important influence. The report argues that institutional religion now has a 'half-life' of one generation. In other words:
two non-religious parents successfully pass on their lack of faith;
two religious parents have roughly a 50-50 chance of passing on their beliefs;
one religious parent does only half as well as two together. "

Non-Protestant second-generation Asian-Americans more likely to make personal choice about religion
"The religion preference of second-generation Asian-Americans is more likely to be influenced by their family tradition if they are Protestant but more by a personal faith choice if they belong to other religions."

"Researchers find that families are the primary determiner of individual religious beliefs," said Ecklund, a postdoctoral fellow in Rice's Department of Sociology. "But America's changing demographics may challenge what we know about the place of families in religious transmission. Studying Asian-Americans is ideal for broadening our understanding of family and religious socialization among second-generation immigrant groups because Asian-Americans are one of the fastest-growing new immigrant populations and the most religiously diverse group of new Americans."
