Note: Trends in non-marital births may be affected by changes in the reporting of marital status on birth certificates and in procedures for inferring non-marital births when marital status is not reported. In particular, the increases from 1993 to 1994 to a great extent reflect improvements in the completeness of reporting of nonmarital births in two states, Michigan and Texas.
1 From 1940 to 1965, the percentage of births to unmarried Black women (shown in italics) includes all unmarried Non-white.
2 Persons of Hispanic origin may be of any race. Data for Hispanics have been available only since 1980, with 22 states reporting in 1980, representing 90 percent of the Hispanic population. Hispanic birth data were reported by 23 states and the District of Columbia in 1985; 48 states and the District of Columbia in 1990; 49 states and the District of Columbia in 1991 and 1992; and all 50 states and the District of Columbia since 1993.
