I am looking for the value of rents by number of rooms in the 1940s census. Unfortunately, even for the 1940 full count there does not seem to be information on the number of rooms (see “dwelling characteristics”) .
However, the 1940 official publications of the housing census (https://www.census.gov/library/publications/1943/dec/housing-vol02.html) contain information on the number of rooms by cities and metro areas. This seems to indicate that the information on the number of rooms was collected in 1940.
Does this mean that I am not searching correctly for the Ipums data?
Or does this mean that for some reason, the data was only published, but not stored?
