Today we released the second round of 2020 Census operational quality metrics. On April 26, we released the first round of quality metrics, along with the first counts from the 2020 Census.
Operational quality metrics provide important information about the quality of the census by looking at how we obtained a response for each address.
In this blog, I provide highlights from today’s release much like we did from the first set released in our Examining Operational Quality Metrics blog.
The first release of the operational quality metrics focused on how we resolved whether each address, including housing units and group quarters, was occupied, vacant, delete, or remained unresolved. This second release focuses on occupied and vacant housing units and the household size of occupied units. Occupied housing units are living quarters, such as a house, apartment or mobile home, with at least one person living or staying there.
In today’s release, we provide the metrics for single- and two-person households categorized by the census operation from which we obtained the response (such as from self-response, Nonresponse Followup, other census operations, or from count imputation), and the percentage of occupied and vacant housing units by census operation.
These metrics enable us to examine how data collection may have varied depending on the size of the household. As with our first release of operational quality metrics, it’s important to keep in mind that a difference among these metrics, across the two decades or among the states isn’t necessarily better or worse, but it’s useful information as we continue to examine census operations.
The metrics are available in an interactive dashboard and a downloadable table. The dashboard makes it easy to compare metrics across states and relative to national figures. (This dashboard is similar to, but separate from, the 2020 Census: Operational Quality Metrics dashboard released April 26.)
Comparable metrics from the 2010 Census are also available in both the dashboard and table.
The metrics from today’s release (as well as the April release) are available on the 2020 Census Data Quality webpage.
Here are a few takeaways:
From a demography standpoint, these preliminary numbers are the first information we’ve shared from the 2020 Census on household size. Additional data on household size will be available in future 2020 Census data products.
From a quality standpoint, the metrics show that the way we collected information for different-sized households is consistent with the 2010 Census, and the consistency suggests comparable quality. We’ll continue to examine these metrics in our operational assessments.
While no single number definitively quantifies census quality, examining these metrics and comparing them across geographies and with past censuses can shed light on how our operations and processes affect our ability to accurately count our nation’s population.
Providing these operational quality metrics is another example of the Census Bureau’s efforts to ensure high-quality 2020 Census counts. With unprecedented transparency, we are sharing the very metrics and methods that we use to review the 2020 Census, and we are planning to issue additional quality metrics alongside the release of the redistricting data.
Other ways that we are measuring the quality of the 2020 Census include:
The Census Bureau is committed to sharing what we know, when we know it, to help the nation understand the quality of the 2020 Census results. We will continue to update the 2020 Census Data Quality webpage as new information becomes available.
