According to the U.S. Census Bureau, the median money income of all families in 1970 was about $9,870, which was about $440 or 4.6 percent higher than the 1969 median of $9,430. However, prices rose approximately 5.9 percent in 1970, and in terms of constant dollars, median family income in 1970 was about the same as in 1969. The median income of middle-income households increased from $54,682 in 1970 to $73,392 in 2014, a gain of 34% . It is important to note that these figures are not adjusted for inflation, so the actual value of the dollar has changed significantly since 1970.
