Thanks, everyone, for your suggestions! Unfortunately, I could not find a readily-available shapefile of state boundaries from British India (1920s-30s era) which could be used to join to data sets by state. It seems that the only option would have been to digitize an historical map (or find a detailed one already digitized), geo-reference it, and then manually digitize the boundaries myself, which I didn't have time for. The professor and I settled on the compromise of merging the shapefiles for modern India, Pakistan and Bangladesh (obtained from http://gadm.org), making some adjustments to match modern states more-or-less with their historical equivalents, and proceeding to map from there. Since this was for illustration during a conference presentation (and not for actual analysis), this compromise was "good enough for government work" [sic]. Thanks again for all of your suggestions. I did collect a couple of new data sources I hadn't know of before (http://gadm.org and http://www.diva-gis.org/). If anyone out there is looking for contemporary international data and you have not yet discovered IPUMS-International <https://international.ipums.org/international/>, one of our students came across it last semester and that also looks handy. Thanks again for being such a great resource!
