The measure used by BSA to determine the growth of Scouting, by any chartered partner, is the number of units they sponsor. For
some years, these figures were not available or were not broken down by chartering organization on-line. The page entitled, Membership Statistics, provides the number of Roman Catholic units, the number of religious sponsored units and the total number of units for each year such information
The membership statistics have been compiled from the BSA's Annual Reports and other BSA and NCCS publications.
Information on the number of Catholic Religious Emblems presented have never really been recorded. What has generally been compiled is the number of Catholic religious emblems that have been purchased by the dioceses. In this case, it is better to view these statistics more as an average than an absolute number of emblems presented in each given year. Some larger dioceses purchase a large number of emblems in one year and present emblems from this supply over the following 3-4 years. Especially if they have the budget and anticipate a price increase in the medals.
Most of this information has been compiled from John Ritchie and then Eagle Regalia, the manufacturers of the Catholic religious emblems since 1941 (until 2007).
