Share of Aggregate Income Received by Each Fifth and Top 5 Percent of Households: 1967 to 2005

Added By Infochimps

The Statistical Abstract files are distributed by the US Census Department as Microsoft Excel files. These files have data mixed with notes and references, multiple tables per sheet, and, worst of all, the table headers are not easily matched to their rows and columns.

A few files had extraneous characters in the title. These were corrected to be consistent. A few files have a sheet of crufty gibberish in the first slot. The sheet order was shuffled but no data were changed.

The tables that were changed (this is table 675):

0166 0257 0362 0429 0445 0446 0459 0461 0462 0464 0465 0466 0467
0469 0479 0480 0481 0482 0483 0484 0485 0486 0487 0559 0628 0629

This dataset consists of a table of 47 rows and 13 columns.

Constant dollars based on Consumer Price Index Research Series Using Current Methods (CPI-U-RS) deflator. Households as of March of the following year. Based on Current Population Survey; see text, sections 1 and 13, and Appendix III. For methodology information, see For definition of median, see Guide to Tabular Presentation


  1. Data reflect implementation of a new March CPS processing system.
  2. Data reflect introduction of 1970 census-based sample design and population controls.
  3. Data reflect full implementation of 1970 census-based sample design.
  4. Data reflect implementation of a new March CPS processing system. Questionnaire expanded to ask 11
    income questions.
  5. Some of these estimates were derived using Pareto interpolation and may differ from published data
    which were derived using linear interpolation.
  6. First year medians were derived using both Pareto and linear interpolation. Before this year, all medians
    were derived using linear interpolation.
  7. Data reflect implementation of 1980 census population controls. Questionnaire expanded to show 27
    possible values from 51 possible sources of income.
  8. Data reflect implementation of Hispanic population weighting controls and introduction of 1980 census-
    based sample design.
  9. Recording of amounts for earnings from longest job were increased to $299,999. Data reflect full
    implementation of 1980 census-based sample design.
  10. Data reflect implementation of 1990 census population controls.
  11. Data collection method changed from paper and pencil to computer-assisted interviewing. In addition,
    the March 1994 income supplement was revised to allow for the coding of different income amounts on
    selected questionnaire items. Child support and alimony limits decreased to $49,999. Limits increased in
    the following categories: earnings to $999,999; social security to $49,999; supplemental security income
    and public assistance income to $24,000; and veterans’ benefits to $99,999.
  12. Data reflect introduction of 1990 census-based sample design.
  13. Data reflect full implementation of the 1990 census-based sample design and metropolitan definitions,
    7,000 hosehold sample reduction, and revised race edits.
  14. Implementation of Census 2000-based population controls.
  15. Implementation of 28,000 household sample expansion.
  16. Data have been revised to reflect a correction to the weights in the 2005 ASEC.
