Important note about Controlled Tier Geolocation Data

Note: We recently determined that three-digit zip code information isn’t available in the v6 CDR CT observation tables for zip codes starting with the number “0”, which was caused by an error with curation rules enabled to protect participant privacy in areas with less than 20,000 inhabitants. These zip codes are instead listed as "00000" like they would be if they came from regions with less than 20,000 inhabitants.

 

This issue doesn’t result in any improper sharing of participant information, but will prevent Workbench users from utilizing three-digit zip code information from the following states: Maine, Massachusetts, Connecticut, Rhode Island, New Hampshire, Vermont, and New Jersey. Our curation team confirmed that this data will be fixed in the upcoming winter release. More information about geolocation data can be found in this article, while further questions about this issue can be sent to the Help Desk at support@researchallofus.org.
