Last week the Census Bureau announced that it will implement updated standards for the collection and reporting of race and ethnicity data set by the Office of Management and Budget (OMB) that are effective as of March 28th, 2024. This is the first time the OMB’s race and ethnicity data standards have changed since 1997. Read more.
Read MoreCensus Bureau data products continue to give insight into changes in mortality trends over the past few years and through the Covid-19 pandemic. Vintage 2022 Population Estimates, which are based on data from the National Center for Health Statistics, take into account final 2021 and provisional 2022 mortality data and allow data users to look at mortality by sex and by race and ethnicity.
Read MoreTo celebrate Native American Heritage month, we explored the Decennial Census data files to find some data on Native Americans living in Connecticut. In this post we share what we found about the tribes with the highest populations in Connecticut, demographics of the Native American population in Connecticut, and where Native populations live across the state.
Read MoreConnecticut’s Department of Public Health (DPH) has determined that the Census Bureau’s vintage 2022 population estimates are artificially high for certain Connecticut towns in 2021 and 2022 due to pandemic-related issues with the counts of residents in group quarters facilities.
This blog post:
discusses what happened;
explains the impact on population estimates for specific towns, planning regions and the state;
delineates which population estimates the state will be using for official purposes; and
provides some recommendations for data users on which version of the population estimates to use, and where to find these estimates.
The 2020 Demographic and Housing Characteristics File (DHC), released by the U.S. Census Bureau in May 2023, is one of many data products released as part of the 2020 decennial census. The DHC file includes detailed tables on topics such as age, sex, race, ethnicity, along with many topics about households and families.
The raw data can be downloaded on the Census Bureau’s website, but CTData has created a 2020 Demographics and Housing Explorer for data users to easily access and explore data found in the DHC file. Click the button or preview below to explore data for your town!
Read MoreAccording to the 2020 decennial census, Connecticut has approximately 1.4 million households, of which 3.9%, or 55,526, are multigenerational. This marks an increase of about 0.3%, or 4,924 households, from the 2010 decennial census. In comparing the change from 2010 to 2020, every planning region in Connecticut experienced an increase in multigenerational households. The smallest increase was in the Lower Connecticut River Valley, with 77 households, or 4.3%, while the largest was in Western Connecticut, with 1,683 households, or 23.5%.
Read MoreAccurate population estimates are vital for informed decision-making and planning for the future. The U.S. Census Bureau produces annual population estimates that provide valuable population insights. This blog post explores the methodology utilized by the Census Bureau to produce these estimates, highlighting the data sources, statistical techniques, and considerations on when to use them.
Read MoreAccurate and reliable population data is essential as we strive to understand our communities and plan for the future. From determining congressional districts to allocating resources for schools and healthcare, population data drives decision-making at all levels of government and beyond.
In this blog post, we'll take a closer look at four commonly used sources of population data: the Decennial Census, American Community Survey (ACS), Population Estimate Program (PEP), and Connecticut Department of Public Health (CT DPH) Population Estimates. Continue reading to learn more about these sources.
Read MoreTo protect respondents’ privacy, for the 2020 Decennial Census the Census Bureau is using a modern disclosure avoidance approach called differential privacy. In brief, differential privacy adds statistical noise—small random additions or subtractions—into the data to reduce the risk that someone could reidentify any person or household.
In this post, we will: (1) describe how differential privacy is applied to the 2020 Decennial Census data; (2) review the Census Bureau’s guidance for 2020 Decennial Census data users; (3) provide an overview of the summary metrics file released by the Census Bureau; and (4) discuss some illustrative examples of the amount of error introduced to certain counts as reported in the summary metrics file.
Read MoreThe United States Census Bureau’s Population Estimate Program released its Vintage 2022 population estimates for towns in Connecticut for July 1, 2022. Bridgeport remains in the top spot, with the highest population at 148,377 people (an increase of 0.14%), but Mansfield’s population data showed the largest increase. Click to explore more.
Read MoreIn 2020, the Census Bureau made some important changes to how they collect and process race and ethnicity data. These changes were intended to better capture the increasingly diverse racial and ethnic identities of the U.S. population, while still following the 1997 Federal Office of Management and Budget (OMB) Standards for the Classification of Federal Data on Race and Ethnicity. However, these changes also raise some questions about the validity of the Census Bureau’s “Two or More Races” classification in 2020, particularly for Hispanic and Latino individuals. They also complicate comparisons with race data from before 2020, making it difficult to assess change over time. In this blog post, we discuss the consequences of the Census Bureau’s recent changes to how they collect and process race and ethnicity data, as well as the proposed revisions to the OMB standards for the classification of federal data on race and ethnicity.
Read MoreToday, the Census Bureau released the first postcensal population estimates for Connecticut’s nine planning regions. These nine planning regions are the new county-equivalent geographic units that the Census Bureau will be using for Connecticut (see our earlier blog post on this topic). This is the first Census Bureau data product to be released using Connecticut’s new county-equivalent geographic units.
Read MoreAt CTData, we often receive questions about changes in migration patterns before and after 2020 and the COVID-19 pandemic. Using three data sources from the U.S. Census Bureau, this blog post will look at recent migration patterns in Connecticut.
Read MoreThe 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.
Read MoreNational Disability Employment Awareness Month is observed annually in October, recognizing people with disabilities' essential roles in a diverse and inclusive American workforce.
From the American Community Survey, 5-year estimates for 2016-2020, we looked at three data tables for Connecticut's population with a disability: population, employment, and median earnings. Below are some of the highlights from the data.
Read MoreThis week marks the end of Hispanic Heritage Month, a reminder for the nation to recognize and celebrate our Hispanic and Latino community members.
In this blog post, we share a profile of Connecticut’s large and vibrant Hispanic and Latino population using data from the 2010 and 2020 Decennial Census and the 2021 American Community Survey (ACS) 1-year estimates.
Read MoreThe Covid-19 pandemic has impacted the lives of Connecticut residents in many ways, from introducing many workers to remote work to exacerbating the financial struggles of others. Last year, the U.S. Census Bureau announced that standard 2020 ACS 1-year estimates would not be released, as Covid-19 severely impacted the data collection process and ultimately resulted in estimates that did not meet the Census Bureau’s Statistical Data Quality Standards. The Census Bureau was able to work through data collection challenges this year and released ACS 2021 1-year estimates on September 15, 2022.
In this post, we analyze changes from pre-pandemic (2019 ACS 1-year estimates) to the most recent time frame of data we have (2021 ACS 1-year estimates) to explore the impact of the pandemic on Connecticut residents and workers.
Read MoreToday, the Census Bureau released 2020 undercount and overcount rates by state from the Post-Enumeration Survey (PES).
