How to read these numbers

Published ACS 2016–2020 commuting flows for workers age 16+. These are sample estimates with source 90% margins of error, not live movement, job vacancies or Census LODES job counts. Flow lines connect county internal points, not travel routes. Counts include only matched US counties in this map; historic/unmatched counties, Puerto Rico, abroad and unclassified workplaces are excluded. Missing flow pairs are not certified zero. Margins of error are retained for individual flows and never simply added into a total.

Map colors span the minimum and maximum available values in your current filters. Point maps locate reference points and do not shade geographic boundaries. Nearby ordering uses straight-line point distance, not a travel route. Public links preserve statistical filters and place identifiers; calculation amounts and search text stay out of the URL.
