                     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
