According to Harvard University professor Robert Putnam, who conducted the research.
New research by the Pew Forum on Faith in Public Life shows young Americans are dramatically less likely to go to church.
"It's a huge change," says Robert Putnam, who conducted the research. This trend started in the early 1990's and continues through today.
Putnam went on to say that in the past two decades, many young people began to view organized religion as a source of "intolerance and rigidity and doctrinaire political views," and therefore stopped going to church.
The research will be included in a forthcoming book, called "American Grace."
