June 28 – “Today, in about 50-60 offices, we began a quality assurance operation that double-checks units judged to be vacant on April 1. It also checks units that we couldn’t find and were recommended to be deleted from our list. Finally, it will call on a set of addresses that were added late to the list and couldn’t be visited during nonresponse followup. This operation will visit about 15 million units and last about a month or so, using about 300,000 enumerators.”

PUMAs? -- What are they?
PUMAs are the zones used for PUMS data
Public Use Microdata Sample
PUMS data is based on individual census records and is available only at large geographic areas. Think of the PUMS dataset as the raw, disaggregate census sample data, at a large enough geographic level necessary to protect the confidentiality of the census respondent.
