Note: Own children are never-married sons and daughters under the age of 18, including stepchildren and adopted children, of the householder or married couple.
This indicator provides the number of households with own children under the age of 18 along with the percentage of these that are single parent households. The percentages are of households with children under 18 years of age, not out of all housing units. Further, it specifies the percentages of households with children under 18 years of age that are single parent father or single parent mother households. Therefore, sum of single father household and single mother households will add to percent of single parent household with own children under 18.
