The median money income of households in the United States was $8,730 in 1970. This was about $340 or 4.1 percent higher than the 1969 figure of $8,390. However, consumer prices rose during the year, and in terms of constant dollars, median household income was about the same as in 1969.¹

An estimated 10.2 million households, or 15.8 percent of the 64.4 million households in the Nation received money incomes under $3,000 in 1970. Households with incomes between $3,000 and $5,000 numbered 7.5 million, or 11.6 percent, in 1970; 11.8 percent, or 7.6 million, had incomes between $5,000 and $7,000; and 18.5 percent had incomes between $7,000 and $10,000. The number of households having incomes above $10,000 was 27.2 million, an increase of 2.3 million households over 1969.

Data in this report were derived from the Current Population Survey conducted by the Bureau of the Census and are subject to sampling variability which may be relatively large for the smaller figures and for small differences between figures. For a further discussion of the sampling variability, see the section on "Source and Reliability of the Estimates" below. The difference between household and family incomes is discussed in Series P-60, No. 62.
