Defining Membership: The most critical methodological problem was that of defining church membership. Since there is no generally acceptable definition of church membership, it was felt that the designation of members rested finally with the denominations themselves. In an effort to achieve comparability of data, however, two major categories were established: "communicant, confirmed or full members," and "total adherents."


Since it was planned to use total adherents in computing percent of church membership to total population, in cases where denominations reported only communicant, confirmed or full members, total adherents were estimated by computer according to the following procedure. The total county population was divided by the total county population less children 13 years and under, and the resulting figure was multiplied by the confirmed members. The 1980 U.S. Census was used to determine for each county the population 13 years and under.
