Census staff will begin in-field address canvassing this week. Address canvassing assists the Census Bureau in maintaining and updating their address list in advance of the upcoming 2020 Census. During In-Field Address Canvassing, field staff, known as listers, visit specific geographic areas within the Self-Response type of enumeration area (TEA) where in-office methods could not assure a complete and accurate address list. Listers identify every place where people could live or stay, comparing what they see on the ground to the existing census address list and verifying, correcting, or adding addresses and location information, as appropriate. Listers knock on doors at every structure in order to verify or update information and inquire about additional living quarters in the structure and/or on the property. If the lister does not find anyone at home, they verify or update address information by observation.
