Consumer Price Index research series using current methods (CPI-U-RS)
presents an estimate of the CPI for all Urban Consumers (CPI-U) that
incorporates most of the improvements made over that time span into
the entire series. More information can be found at

As stated in the Census's "Source and Accuracy of Estimates for
Income, Poverty, and Health Insurance Coverage in the United States:
2011" (http://www.census.gov/hhes/www/p60_243sa.pdf):
Estimation of Median Incomes. The Census Bureau has changed the
methodology for computing median income over time. The Census Bureau
has computed medians using either Pareto interpolation or linear
interpolation. Currently, we are using linear interpolation to
estimate all medians. Pareto interpolation assumes a decreasing
density of population within an income interval, whereas linear
interpolation assumes a constant density of population within an
income interval. The Census Bureau calculated estimates of median
income and associated standard errors for 1979 through 1987 using
Pareto interpolation if the estimate was larger than $20,000 for
people or $40,000 for families and households. This is because the
width of the income interval containing the estimate is greater than
$2,500.
We calculated estimates of median income and associated standard
errors for 1976, 1977, and 1978 using Pareto interpolation if the
estimate was larger than $12,000 for people or $18,000 for families
and households. This is because the width of the income interval
containing the estimate is greater than $1,000. All other estimates of
median income and associated standard errors for 1976 through 2011
(2012 ASEC) and almost all of the estimates of median income and
associated standard errors for 1975 and earlier were calculated using
linear interpolation.
Thus, use caution when comparing median incomes above $12,000 for
people or $18,000 for families and households for different years.
Median incomes below those levels are more comparable from year to
year since they have always been calculated using linear
interpolation. For an indication of the comparability of medians
calculated using Pareto interpolation with medians calculated using
linear interpolation, see Series P-60, Number 114, Money Income in
1976 of Families and Persons in the United States
