Hello! I am a graduate student using IPUMS for the first time and it would be great if someone can help me.
I am doing a repeated cross-section analysis. From what I read, I gathered that PUMAs are not comparable over time as the boundaries change over time. However, I am using data from 2012 to 2019 (1% ACS), which is using similar boundaries (2010). So, my first question is, if I use data from 2012 to 2019, can the PUMAs be compared over time?
The second thing I am struggling with is matching the PUMAs to counties. I have some data in county level, and it would be really great if I can match the counties with PUMAs. Can anyone help me with the steps to do this? or guide me to resources that can do this? that would be really helpful for me. Thank you so much!
