Many unmarried Americans do not identify with the word single because they are parents have partners or are widowed.
"National Singles Week" was started by the Buckeye Singles Council 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. 19-25 in 2010) 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.
