In short, no.
Vast differences in theology and accounting practices make it nearly impossible to really know how many members a church body has, whether active or occasional worshippers. That, in turn, makes side-by-side comparisons nearly impossible....Often a church's understanding of membership -- how it is started, how it is maintained and how it can be revoked -- influences counts........Roman Catholics, the largest U.S. church with a reported 69 million members, start counting baptized infants as members and often don't remove people until they die. Most membership surveys don't actually count who's in the pews on Sunday....That means it is possible, for example, to be born Catholic, married Methodist, die Lutheran and still be listed as a member of the 1 billion-member Roman Catholic Church. "The Catholic understanding of membership is that a person becomes a member upon baptism and remains a member for life," Gautier said. "Whether you show up at church or not is not what determines whether you're a member."

Many Catholics drift from parish to parish without formally changing their membership and often don't report deaths in their families, the newspaper said.

Give it a rest Alex Murphy, just go ahead and become Catholic already!
You can’t whine that much about numbers and be that jealous that no one listens to you without a deep seated desire, so come on aboard and count yourself a sucker. Come on home.
Nobody here cares how many Catholics there are, they just want MORE.

This isn’t really relevant to counting. I live in a small city where we have 2 primary parishes and there are 3-4 in the smaller outlying communities. We belong as members to St. Mary’s as my wife’s family helped to build that church after immigrating from Germany. However, we most often attend the church across the city as we like the hour and music at the Mass. We go back and forth and know each community fairly well. But for counting purposeds, going from parish to parish simply doesn’t matter. We are counted once in the official parish we are registered at.

I don’t know if it is being done elsewhere, but the Archdiocese of St. Louis has for the past two years been counting who’s in the pews.
