2020 Census Quality Review Strategies for Municipal and County Officials

The State Data Center has developed a three-step process for communities to utilize when conducting a detailed review their 2020 Census population data.

Reviewing, identifying and correcting errors in 2020 Census data does not involve a recount of people. Instead, it is a check to ensure that the living quarters reported by the Census Bureau are in the correct location.

To expedite a municipal review, our three step process is focused on locating only those errors which can be submitted to 2020 Census review programs sponsored by the Census Bureau. Two review programs are available.

2020 Count Question Resolution (CQR) Operation

CQR allows communities to request that the Census Bureau review a narrow set of processing errors that include:

  • Incorrect corporate boundaries used in the calculation of the total population and housing unit counts
  • Correct errors where living units (housing units and group quarters) and their inhabitants were reported at an incorrect location – such as outside a corporate limit

Post Census Group Quarters Review (PCGQR)

PCGQR is a new program designed to correct 2020 Census miscounts of residents at group quarter facilities, especially in instances where residents were displaced by the COVID-19 pandemic or facility restrictions prevented accurate enumeration.

Getting Started

The review is broken into three parts. For each part, an interactive map with the appropriate census data and detailed directions will guide you through the steps to complete a 2020 Census review for your community.
