Earnings from other work included farm self-employment earnings


99999999 = 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.


OINCFARM reports net earnings as a tenant farmer, sharecropper, or operator of one's own farm during the previous calendar year, if such work did not constitute the longest-held job during that period. The amount earned (in wages, salary, or earnings from self-employment in a business or farm) from the longest-held job during the preceding calendar year is reported in INCLONGJ.

Imagine that an individual considered raising crops on her own land to be her primary job, and considered money earned by harvesting crops on another farmer's land for a few days, using her own equipment, to be a secondary "own farm" job. In such a case, net earnings from the sale of her own crops would be reported as income in INCLONGJ; earnings from harvesting crops for another farmer would be reported as "other" self-employed own farm income in OINCFARM; and the sum of earnings from crop sales and farm equipment rental would constitute INCFARM. If, instead, she grouped together all net earnings from crop sales and income generated from the use of her equipment into a single "own farm" business, all of this net farm income would be reported in both INCLONGJ and INCFARM, and the value of OINCFARM would be zero.

Imagine, instead, that as reported in SRCEARN, an individual worked as an employee earning wages for the primary job, but earned additional income working part of the year on their own farm. In such a case, wage income from the primary job would be reported in INCLONGJ; all self-employed farm net business earnings would be reported in OINCFARM; and the value of OINCFARM and INCFARM would be the same.

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


Along with the effects of inflation, OINCFARM may be affected by changes in reporting practices. Beginning in 1994, individuals could report their earnings in monthly, weekly, or bi-weekly amounts, together with the number of such pay periods, rather than as an annual sum. This change in reporting practices probably increased the precision and accuracy of the income figures for OINCFARM beginning in 1994, by reducing rounding and estimation.

Just as OINCFARM reports net farm self-employment earnings from employment other than the longest-held job, OINCBUS and OINCWAGE report net income from non-farm self-employment and from wages or salary as an employee of a business, respectively, if such work did not constitute the longest-held job during the previous calendar year.
