Definitions: Births occurring to women who were unmarried at the time of the birth.
Marital status was obtained from a direct question on the birth certificate in 48 states and the District of Columbia. In Michigan and New York, marital status was inferred from other information on the birth certificate. In 2003, marital status was also imputed for some birth records in the 48 states and the District of Columbia where it was not reported from the direct question. Puerto Rico and Virgin Islands are not included in the U.S. Average.

recent Census counts. Cities for which data is collected may change
Note: The District of Columbia, Puerto Rico and the U.S. Virgin Islands are
not included in maps and rankings because they are not states and therefore comparisons on many
indicators of child well being are not meaningful.
