What does "family market value" mean w.r.t. "SCHLLUNCH"?

I'm trying to figure out what "Family market value" means for several of the poverty measures including "SCHLLUNCH" and "FOODSTAMP", but the documentation is vague and the questionnaire text is not available. Does this mean how much they spent, or what is the market value of what the family spent, or how much value the family places on what they spent? Of maybe none of these options -

The documentation is vague on these variables. We are now in the process of upgrading the description of these values. In general, "family market value" represents the dollar value of the benefit in question. Therefore these values identify the equivalent dollar value of just giving cash rather than the benefit. These values are enumerated slightly differently across the SCHLLUNCH, HOUSSUB, and FOODSTAMP variables. FOODSTAMP is reported directly by the respondent. (See section 5.11 in the ASEC technical documentation.) SCHLLUNCH is imputed based on how many individuals within a family receive school lunches. HOUSSUB is also imputed based on information about the market value of housing units in the family's geographic area. I hope this helps.

Is the data of these variables monthly or yearly?

Good question. Although the SCHLLUNCH and FOODSTAMP variables are in terms of annual values, the HOUSSUB variable is in terms of monthly values. This is a bit confusing, so do note that the IPUMS CPS team is planning on revisiting how these variables are presented. When any revision is made it will be noted here.
