In Alaska, West Virginia and other mostly rural states, census takers relied more on the word of neighbors, landlords and others for information about a home’s residents. In New Jersey, New York and other more densely populated states in the Mid-Atlantic region, they were more likely to come away from a household lacking basic information on race, sex and ethnic background.
An Associated Press review of the first data-quality measurements released by the U.S. Census Bureau last month shows some early patterns that may point to red flags in the data that could emerge when more detailed numbers from the 2020 census are released in August.
While it’s too early to reach any conclusions about the accuracy of the data gathered during the once-a-decade head count, these types of responses – a reliance on proxies for answers and just a head count with no basic demographic information – result in poorer quality data compared to other methods.
Poor quality data can diminish the political power and resources available to communities across the U.S.: Children who are missed in the census deprive communities of money for building schools, and undercounting racial or ethnic minorities prevents them from forming minority-majority political districts.
The bureau released data quality measurements last month as part of an effort to engender confidence in the numbers following a head count challenged by the spread of the new coronavirus, concerns about politicization by the Trump administration and natural disasters. The bureau also is allowing a team of outside statisticians to perform quality checks.
