How do I distinguish high-school dropouts from non-high school dropouts across years in IPUMS-CPS?

I am trying to distinguish between high school dropouts and non-dropouts in IPUMS-CPS using EDUC from the years 1979-2000. The categories don't match from before 1992 and after 1992, and so there is a huge break in the data. The variable description says you can construct a general EDUC code from EDUC by only reading the first two columns...but I don't know which two columns it's talking about.

Your definition of "high school dropout" will dictate exactly how you identify such respondents in the CPS data. For instance, you could define high school dropouts as respondents over a certain age (e.g. 19) with a reported highest grade completed (EDUC) of either Grade 9 (040), Grade 10 (050), or Grade 11 (060). The difficulty arises in how you deal with those who completed Grade 12 without receiving a diploma. Unfortunately, sufficient data was not collected to maintain a consistent definition for this group across the 1992 change in the educational attainment question.

Specifically, for samples prior to 1992, respondents were not directly asked if they received a HS diploma or equivalent. The relatively small number of respondents that reported completing less than 1 year of college are identified as receiving a HS diploma or equivalent (EDUC=073), but the substantially larger group of persons that completed 12th grade have an unknown diploma status (EDUC=072). Due to this lack of detail, those captured in recent years by EDUC code "071: 12th grade, no diploma" cannot be similarly identified in pre-1992 samples.

As for constructing a general EDUC variable, the documentation is referring to the first two digits of the EDUC code, e.g. "01" corresponds to 1st-4th grade, "02" corresponds to 5th-6th grade, "03" corresponds to 7th-8th grade, etc. Using the first two digits provides an education variable that is consistent across time by sacrificing detail.

Hope this helps.
