I am having trouble locating something that I have found on the IPUMS site in the past, information about young children in the sample for the first few years of IPUMS-CPS micro data. I know that prior to some early date (1966?) data on children under some age (14?) was not collected. Can you tell me where that is documented?
I am also puzzled by some places that this information isn’t. For instance, NUMPREC is described as fully comparable across years. Is this an error? If not, what is the rationale for comparability between years that do and don’t count children?
Finally, I would be extremely interested if you knew of any study by anyone ever to impute children to households for these early years. I believe such imputation is necessary if we are to do adult-equivalent equal-population quantiles that reach back to these early years, as is necessary for .comparability with distribution estimates for later years.
