Address Canvassing—the first major field operation of the 2020 Census—is well underway. Address Canvassing improves and refines the Census Bureau’s address list of households nationwide, which is necessary to deliver invitations to respond to the census. While close to two‐thirds of the nation’s address list was reviewed from Census Bureau offices, the remaining third (about 50 million addresses) are being reviewed in the field.

All 40 Wave 1 area census office (ACO) spaces have been accepted and in‐field address canvassing work begun at 39 of the Wave 1 ACOs in August. The one remaining Wave 1 ACO, in Caguas, Puerto Rico, will not open with the other Wave 1 ACOs because address canvassing will no longer take place in Puerto Rico due to the decision to place the entire island in the “Update Leave” Type of Enumeration Area for the 2020 Census. The Caguas office will open with the Wave 2 ACOs.

Address canvassing production began in the seven early start ACOs on August 4, and as of August 18, includes all 39 Wave 1 ACOs. The Census Bureau planned for an early start within seven ACOs (Beckley, WV; Kansas City, MO; Milwaukee, WI; Oklahoma City, OK; Providence, RI; Raleigh, NC; and Seattle, WA) to allow a gradual ramp up to the full production and to quickly address issues before the remaining 32 ACOs began address canvassing.

As of August 26, more than 28,000 Address Canvassing Listers have been hired. Of those, more than 20,000 listers have been deployed to the field. Address Canvassing is progressing slightly ahead of schedule with 262,099 blocks completed (257,156 blocks were planned for this point in time). Twenty percent of the total in‐field address canvassing workload has already been completed (or 9.9 million of the 50 million addresses).
