Median household income rose to approximately $7,700 in 1968 from the 1967 median of about $7,200. Although these figures represent an increase of about 8 percent, because of price increases the gain in real purchasing power is about 3.5 percent.
There are approximately 10.8 million households, or 17.4 percent of all households, which received money incomes of less than $3,000 in 1968. This number represents a significant decrease from 1967 when 11.9 million households, or 19.7 percent, were in this income category.
Another 8.1 million households, or 13.1 percent of the total number, received incomes between $3,000 and $5,000 in 1968; 8.6 million, or 13.9 percent, had incomes between $5,000 and $7,000; and 13.0 million, or 21.1 percent, had incomes between $7,000 and $10,000. The remaining 34.6 percent of the households, or 21.3 million, received incomes of over $10,000, which represents a 4.7 percentage point increase from 1967 in the number of households in this income category (in current dollars).
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.
Census statistics date back to 1790 and reflect the growth and change of the United States. Past census reports contain some terms that today’s readers may consider obsolete and inappropriate. As part of our goal to be open and transparent with the public, we are improving access to all Census Bureau original publications and statistics, which serve as a guide to the nation's history.
