This interactive tool from the New York Times analyzes census data since 1900, and shows the make-up of households in the U.S. For example, in 2009, about 8 million households in the U.S. consisted of a married couple with two children (about 7% of all households). That’s almost the exact same percentage as in 1900.
As for other types of families, the percentage of households with single women and two children increased from about .4% to 1.6% in the last century, and recent data indicate that more than 62% of those households has an income below $30,000. Male unmarried partners with one child make up about 17,000 households in the U.S., and unmarried female partners with one child account for about 30,000 households.
