Chuck somewhere like slides 51-54 of this presentation from earlier this week, is my discussion of workers leaving their res county to work. it is a major national phenomenon which I have tracked over the years and Fairfax County is the poster child with an 8,000 difference between jobs and workers and about a half million flows across the county borders. I have looked at counties in Md where they have similar J/W ratios close to one and there are massive flows – so much for job worker balance as a solution! What we need is the soviet and Chinese approach where the electrical workers cooperative is housed just across the road from the electronics factory. Come to think of that we did that back in the bad old days—remember the pathetic houses clustered around the factory gate – the whistle blew and everyone went to work. I like your index idea – what I have used is the ratio of the potential workers crossing the border to the actual. Best, Alan Alan E.

I'm basically using the commute flow data (county-of-residence, intra-county, county-of-work) from Tables B08007 and B08501. Here are the three posts: https://censusmaven.wordpress.com/2019/02/26/exploring-jobs-housing-balance… https://censusmaven.wordpress.com/2019/02/27/exploring-jobs-housing-balance… https://censusmaven.wordpress.com/2019/02/28/exploring-jobs-housing-balance… The blog home is here: https://censusmaven.wordpress.com/blog/ This is the kind of "mental floss" activities that I do when I'm not watching baseball or going on international trips. I still get a kick out of it, even after being retired for 9 years and 5 months! :) I have other ideas for this master county-level database, and would love to here from you all, as well.
