I’m looking to study the evolution of some specific outcome variables in metro areas throughout the 20th-21st centuries. Of course, MSA definitions change over time. I figured the way I would proceed is by fixing my geographic MSA units over time by using a single, contemporary MSA definition.
I wanted to know if there are any pre-constructed crosswalks from earlier geographic units (e.g. earlier MSA’s, counties, cities, etc.) to modern (eg. 2010) MSA definitions. The “comparability” of the metarea variable does have a county mapping across decades to contemporary MSA, but perhaps there is something that is a bit more straightforward or that is in more common use that I’m unaware of.
Just to be very clear, for example: I’ll download the 1930 (full) census, which includes geographic household variables for county, city, state, and metroarea. Is there a dataset that would very simply map any of these geographic units to a 2010 metro area (MSA)?
Sorry if this already has an answer—I haven’t been able to find anything more direct myself.
