Dear IPUMS staff, I was told that both Metarea and Metfips are not consistent along the year.
So now I am very very confused about which variable to use if I want to aggregate data to MSA level.
Specially, my question is:
I want to look at the distribution of household income in each MSA from 2005-2016.
So I need to aggregate data to a “Year-MSA panel” using CPS ASEC.
Can you give me some suggesstions about which MSA variable can I use to aggregate data?
