Income from worker's compensation


999999 = N.I.U. (Not in Universe).

The Census Bureau applies different disclosure avoidance measures across time for individuals with high income in this variable. Detailed explanations of these methods, topcodes, and replacement value and swap value thresholds are available here.


INCWKCOM indicates how much pre-tax income (if any) the respondent received from worker's compensation payments or other payments as a result as a job-related injury or illness. Income from sick pay and disability retirement were not counted as income under INCWKCOM.

Amounts are expressed as they were reported to the interviewer; users must adjust for inflation using Consumer Price Index adjustment factors.


Apart from the effect of inflation, INCWKCOM is largely consistent over time. From 1988 to 1994, respondents reported a single figure for the year. Beginning in 1995, respondents could report amounts for smaller time intervals, such as weekly, bi-weekly, twice monthly, or monthly, along with the number of payments.

For 1962-1967, the value of income from worker's compensation is subsumed in the INCUNERN variable, which encompasses all income from sources other than wages and salaries (INCWAGE), non-farm businesses (INCBUS), and farms (INCFARM).

For 1968-1987, the value of worker's compensation payments from the government is included in the INCGOV variable, on income from unspecified government programs. Worker's compensation payments from non-governmental sources is included in the INCALOTH variable, covering income from alimony, child support, and other unspecified sources for the same period.

Comparability with IPUMS-USA

The census forms for 1970 and 1980 mentioned worker's compensation, but no census year separately reported income from this source. Income from worker's compensation was included in the residual INCOTHER (other income) variable.
