Pedro H. Albuquerque, "A Practical Log-Linear Aggregation Method with
Examples: Heterogeneous Income Growth in the U.S.", Journal of Applied
Econometrics, Vol. 18, No. 6, 2003, pp. 665-678.

The empirical section of this paper uses American household income data from
the Current Population Survey (CPS), published by the U.S. Census Bureau.
Two variables, with yearly observations ranging from 1967 to 1999, were
utilized: mean household income (in 1999 Dollars), and household income
inequality (Theil's second measure or mean logarithmic deviation). The data
can be found on the Census Bureau web site. 

The ASCII data file (albdata.data) presents the observations for the two
yearly series. The first column is the year, the second is mean household
income, and the third is the mean logarithmic deviation of household income.
