[This post](https://forum.ipums.org/t/cps-has-data-available-on-multiple-job-holders-where-is-the-comparable-variable-in-ipums-cps/440/1) suggests a way to merge unprocessed NBER March CPS data with IPUMS CPS data. I’ve been able to complete this merge successfully for many years (1966, 1968, 1969, 1971-1975), but there are problems in 1964 and 1967.

The NBER and IPUMS data appear to contain the same observations, but in a different order. E.g., the 13th observation in the 1967 IPUMS data is a 23 year old male who is married to a 24 year old female (obs 14). These people appear to be the 12th and 13th observations in the [NBER data](http://www.nber.org/data/current-population-survey-data.html). Results for 1964 are similar.

Do you have any information which might save this merge? I know that I can process everything using the NBER data, but would like to fix the merge if this can be easily done.
