I grant any researchers with appropriate Census-approved project permission to use my exact research files provided that those files were among the ones that they requested when the approval was obtained (a Census Bureau requirement). These files can be found by searching for the DOI of [this archive/ this article] amongst backups/archives made in [month of archive]. I authorize the editorial staff of the [JOURNAL] to provide my statement of cooperation to any researcher who requests it, as well as to the U.S. Census Bureau or any agency cooperating with the Census Bureau in supervising research that uses the restricted-access data that I have used.
