Income Data for Policy Analysis: A Comparative Assessment of Eight Surveys. Tabulations of Income Allocation and Rounding

12/23/2008

Two sets of standard tables showing the frequency of allocation and its contribution to total dollars were prepared for the five general population surveys, which provided full identification of allocated amounts. The first set of tables presented estimates of allocation by source of income (Tables III.6 and III.7), and the second set presented estimates of allocation by demographic characteristics (Tables III.8 and III.9).

Estimates of the frequency of rounding were prepared for the five general population surveys and the PSID. Table III.10 illustrates the first of six tables. This table presents estimates of rounding for total family income. Column one provides estimates of rounding based on reported amounts while column two provides estimate for allocated amounts. Additional tables were prepared for personal earnings, personal wages and salaries, Social Security, retirement income, and total personal income. NHIS collects only total family income and personal earnings, so the tables for that survey were limited to these two sources. The PSID tables included five sources besides total family income, but they were specific to that survey.
