No, though some populous counties do have portions that show up as non-urbanized in the Census ACS data so you can get the information broken out by urban v non-urban.
I was just making a more general statement that by comparing populous counties within a particular state you can see that, in general, the more highly educated residents are clustered in the population centers and metro areas, even when you factor for things such as age and overall size of population. I like that link that
@kjel posted as they have an "Rural-Urban Continuum Code" so you can also sort the counties that way. Though there are always exceptions like Leelanau County in Michigan which has 47% of their residents completing college but only about 20,000 residents. Areas that are popular vacation destinations or with a disproportionate number of retirees are common exceptions. It will be interesting to see how the distribution of those with college degrees changes over the next ten years or so as remote work becomes more of an option, especially among those in tech and financial services...
I haven't looked at crime stats in a long time (last I looked deeply into it was probably about a decade+ ago) but there used to be a lot of differences between how/when crimes were reported from one local jurisdiction to another, and those differences became more pronounced when you tried to compare jurisdictions between different states. There was also a lot of data that showed that a lot property crime went unreported in the crime stats or were more often pleaded down to something lesser or thrown out in court in more exurban and rural areas than in suburban communities and core cities and that had an effect on skewing the data. Now,
why those offenses were going unreported in the crime stats or the suspects were more likely to get more favorable treatment in the system is an entirely different story...
