UPDATED May 17, 2020
From the U.S. Census:
50.1% of households have responded to the 2020 Census since invitations began arriving in mailboxes on March 12.
The 2020 Census response rate map shows how cities and towns across the country are now responding. The map will be updated daily for everyone to see the response rate in their area and compare it to other areas across the nation. The map also shows the comparable response rate from the 2010 Census for each geography.
In late February, the map launched with 2010 Census response rates as a reference point for states and cities, including down to the census tract level (areas with about 4,000 households). People can now view both 2010 and 2020 Census response rates on the map.
The map only includes data from households that respond to the census online, by phone or by mail and not those who are counted by a census taker in person. For example, the map does not reflect the people who are being counted through special operations, such as people living in group housing, transitory locations, or remote areas.
Later, census takers will visit households that have not yet responded to collect their responses in person. The response rate map gives a preview of areas where census takers may need to follow up with more households if they do not respond online, by phone or by mail.
Response rate data [is also] available in the public API.
