Ed Stetzer, missiologist with the North American Mission Board (NAMB), introduced me to a great website for exploring research concerning the church in America.

The Center for Missional Research exists to help Christian leaders make strategic missional decisions by researching North American cultures, analyzing ministry effectiveness of churches, understanding communities where churches minister, and building connections among churches.

There’s a lot of information. If you are interested in the rise of house churches in the US, check out this link.
