CTData 2022 Mini-Conference Recap: What You Need to Know about Using Census 2020 Data

The 2020 Decennial Census faced unprecedented challenges: the COVID-19 pandemic, political interference, natural disasters, and the implementation of a new approach to privacy protection called differential privacy. We invited two experts to share what this means for using Census 2020 data. Amy O’Hara is a Research Professor in the Massive Data Institute and Executive Director of the Federal Statistical Research Data Center at Georgetown University. Elizabeth Garner is the State Demographer at the Colorado State Demography Office.

CTData Conference Recap: Population Estimates & Updates

Each year, the Census Bureau produces population estimates for each state and county that are different than the ACS t-year survey that many of us are used to. These are called Population Estimates, and these are the official measures of population & housing units between decennial censuses. In this conference session, you will learn about the methodology that undergirds these annual data and learn about the ways you can access the data through the US Census Bureau.

Census Bureau Releases Coverage Estimates for Housing Units from the 2020 Post-Enumeration Survey: Were Connecticut’s Housing Units Accurately Counted?

On August 16th, the U.S. Census Bureau released coverage estimates for housing units from the 2020 Post-Enumeration Survey (PES). These results provide insight into the accuracy of the 2020 Census counts of housing units (not to be confused with counts of people). The coverage estimates are provided nationally, by region and state, and by type of housing unit (e.g., single unit versus multiunit and owner- versus renter-occupied) and characteristics of the householder (e.g., race and ethnicity).

This blog post reviews key findings for housing unit coverage estimates nationally, and for Connecticut and other states.

New Census Bureau Data on Young Adult Migration: Connecticut Experiences More Out-Migration than In-Migration of Young Adults, with Rates Varying by Parental Income and Race/Ethnicity

On July 25th, the U.S. Census Bureau in collaboration with Harvard University released a new interactive data tool on young adult migration. The data tool tracks patterns of migration between all 741 commuting zones in the U.S. from childhood (measured at age 16) to young adulthood (measured at age 26), for individuals with a Social Security Number who were born in the U.S. between 1984 and 1992.

Migration patterns are provided for the full sample and disaggregated by parental income quintile and by four categories of race and ethnicity (Hispanic, non-Hispanic Asian, non-Hispanic Black, and non-Hispanic White).

In this blog post, we report some findings from the tool on migration patterns for Connecticut residents.

Learn about the Census Bureau's Post-Secondary Employment Outcomes (PSEO) Data

The Post-Secondary Employment Outcomes (PSEO) data are an experimental data product developed by the Census Bureau that provides earnings and employment outcomes for college and university graduates by degree level, degree major, and post-secondary institution. The data are generated by matching university transcript data from participating universities with a national database of jobs compiled by the Longitudinal Employer-Household Dynamics Program (LEHD) at the Census Bureau.

PUMA Delineations for 2020

As the Census State Data Center, CTData is required to delineate the 2020 PUMA boundaries. An important component of this delineation process is to elicit community feedback from the data users in our state. We began this process in December during our conference session, “PUMAS: What are they and how you can help,” where we laid out the background of what PUMAs are and why this issue matters on our website as well as through an Op-Ed published by the CT Examiner. We also spent time creating options for the 2020 PUMAs so that data users could respond to them at a meeting we held this week. Read on to learn what was decided this week based on community input.

Most Common Race or Ethnicity by Census Tract

When looking at census data for Connecticut, the state-level population data can hide the diversity that lies within our state. The Census Bureau analyzed the national data by county to uncover the racial and ethnic diversity that lies underneath the top-line stats about which racial or ethnic identity is most common. We wondered what Connecticut looks like when we explore the second and third most common racial and ethnic identity by census tract.

How Diverse is Connecticut?

Diversity can often be difficult to quantify, especially when discussing race and ethnicity. The Census Bureau provides accurate and recent demographic data through the American Community Survey and Decennial Census, but how can we use this data to measure diversity in Connecticut towns?
