The tables presented here are preprints of tables 181, 182, 186, 188, 280, 281, 282, and 291 (or portions thereof) from Final Report PC(1)-lD, which contains additional summary information on the detailed characteristics of the population.

In 39.6 million families, or seven out of eight of the 45.1 million families in the United States in 1960, the head was a married man with his wife present in the household. Of these husband-wife families, 23.5 million had own children (unmarried children under 18 years old) living in the household. The proportion of husband-wife families with children was highest (86 percent) where the head was 25 to 44 years old and lowest (14 percent) where the head was 55 years old and over.

There were 5.5 million families with no spouse of the head present. Of these, 2.2 million, or 40 percent, had own children under 18 living in the household. There were 1.9 million families with a female head and children, as compared with only 300,000 families with a male head with children but no wife present. Families with female heads under 35 with children numbered 662,000, or 9 out of 10 of the families with a female head of this age

There were 64.0 million unmarried persons under 18 years of age in the United States in April 1960. About 56.3 million, or 7 out of 8, were children living with both parents, 5.8 million were children living with only one parent, and 1.8 million were classified as living with neither parent.
