At the end of 2008, 5,320 churches were reported to be within the UCC, averaging 210 members. Sixteen churches were reported to have over 2,000 members, but 64% had fewer than 200 members. The latter statistic probably indicates where most of the denomination's declining membership has occurred, in formerly mid-sized congregations between 200 and 500 members or so. The reduction in a typical church's size has also meant that, increasingly, many congregations are no longer able, as they once were, to afford a full-time, seminary-educated pastor, and that some of them have to rely on alternatives such as one of their members serving the church under a license, the use of recently retired clergy on a short-term basis, or ordained ministers serving the church on a half-time (or less) basis while earning their primary income from chaplaincies or other occupations. While this has been occurring to a lesser degree in other mainline denominations as well, the UCC's congregational polity allows for churches to adopt such approaches without ecclesiological restraint, as might happen in a more hierarchical denominational structure.
