^aPoint estimates are calculated using imputed values for date of marital separation

^bIn 2002, because of the large amount of missing marital separation dates, parent's marital status at birth could not be determined with certainty for 5% of children in 2002. Bounds were created by assuming 1) that all of these children were born to married parents, and 2) that all were born after the marriage dissolved.
