Hi Everyone! I am currently working on a project to look at the effects of air pollution on housing values in Arizona and New Mexico. I have merged the IPUMS USA data with EPA Air quality data in the county level. The problem with the IPUMS data, there are some counties missing which makes me difficult to analyze the result in the county level. Especially, Bernalillo county is missing in where most of the New Mexico populations are living. Could anyone give me a suggestion how can I get individual-level data for housing characteristics? It will be a great help for me. Thank you.
