The Buckeye Singles Council started “National Singles Week” in Ohio in the 1980s to celebrate single life and recognize singles and their contributions to society. The week is now widely observed during the third full week of September (Sept. 17-23 in 2017) as “Unmarried and Single Americans Week,” an acknowledgment that many unmarried Americans do not identify with the word “single” because they are parents, have partners or are widowed. In this edition of Facts for Features, unmarried people include those who were never married, widowed or divorced, unless otherwise noted.
