Is there a straightforward way to create an extract where some variables (age, race, race, birthplace, puma) employ harmonized coding and others (detailed educational attainment) do not?

Thanks, in advance.

In [IPUMS USA](https://usa.ipums.org/usa/), when source variables are available, they are listed on the Source Variables tab of a given variable. For example, the [GRADEATT variable](https://usa.ipums.org/usa-action/variables/GRADEATT#description_section) has a number of year-specific source variables available under the [Source Variables tab](https://usa.ipums.org/usa-action/variables/GRADEATT#source_variables_section). This allows you to easily add both harmonized and source variables into the same data extract.
