Did you have an ancestor or friend/associate/neighbor (FAN club) of an ancestor who was chosen to answer the sample questions on the 1950 US Census? I've been paying attention to the income questions, in particular, as I put my ancestors into context.
Above $10k?
According to the 1950 US Census Enumerator's Training Manual, if someone reported income above $10,000, the answer would be listed as $10,000+ on the population schedule--regardless of how much higher their actual income might have been.
Income answers from the 1950 US Census were coded for data entry and analysis, as were a few other questions (such as birthplaces and occupations).
Decoding the code
As you can see from the code circled in image at top, the income listed was $10,000+. and the code was 9V.
Huh? Turns out, 9V is the code for more than $10,000, as I read on the History Hub page about decoding 1950 US Census answers for Column 31.
In this case, I'm willing to bet that the actual income was far above $10k. Why? Because this is the 1950 US Census entry for Jack Cohn, VP of the film giant Columbia Pictures. One of Jack's nieces married a first cousin of my father. Of course I'm looking at the answers given by these and other in-laws in the 1950 US Census 😉
