America Migration Within Its Own Borders: An Interactive Map and Visualization at Forbes by Jon Bruner

At Forbes, John Bruner has an "interactive visualization" of Migration in America based on IRS data, which traces patterns of migration for every county in the nation -- red/orange for "moving out" and blue/green for "moving in".

See in this regard Raven Molloy, Christopher L. Smith, and Abigail Wozniak, Internal Migration in the United States, [and update?] Finance and Economics Discussion Series, Divisions of Research & Statistics and Monetary Affairs, Federal Reserve Board, Washington, D.C., 2011-30. NOTE: Staff working papers in the Finance and Economics Discussion Series (FEDS) are preliminary materials circulated to stimulate discussion and critical comment. The analysis and conclusions set forth are those of the authors and do not indicate concurrence by other members of the research staff or the Board of Governors. References in publications to the Finance and Economics Discussion Series (other than acknowledgement) should be cleared with the author(s) to protect the tentative character of these papers.

[Our comment: There is in our mind no excuse for the sloppy way in which the above papers are dated and "marked". 2011-30 means nothing to an average reader. What is wrong with giving the EXACT date of publication (day, month, year), while CLEARLY MARKING on the first page that this is a so-called "WORKING PAPER", its version ("Version 1" etc.), if applicable, etc. Authors and publishers assist no one by adding confusion to the world through incomplete or obscure identification of materials!]
