I am trying to estimate the number of children under 14, by race and Hispanic status, for the years for which the CPS does not count such children, 1962-1967. Specifically, I want to use Census population estimates for this age range or IPUMS-USA data for 1960 and 1970 to impute values in the CPS. Is there a straightforward way of estimating the population of such CPS counterfactually eligible children from Census estimates – some correction factor for the different scope of eligible universe in the two data sets?

Will the number of such children – children covered by the CPS but not the Census, or visa versa – be substantial? I am thinking that this would be children in group quarters plus the children of members of the armed forces. I am not sure how the CPS treats employed spouses of armed forces members in terms of eligibility. Are there other groups of children where the difference in coverage is important?
