U.S. Church Membership Down Sharply in Past Two Decades

That isn't necessarily a meaningful bit of information.  Over the past 30 to 40 years, there has been a move away from church membership or an increasing number of people within churches who are not taking to step of becoming full members.  I myself have attended the same church for 15 years, and my family and I have yet to become members of the church.  My older brother serves as an Elder in the same church and is a member, but even he waited several years before taking that step.  So I would suggest that this probably has as much or more to do with that development within the church than it has to do with any genuine decline.
