2024 NHIS Data Early Release: Q2 (April – June) Estimates Show Uninsurance Remained Stable While Many Shifted from Public to Private Coverage
November 14, 2024:On November 8, 2024, The National Center for Health Statistics (NCHS) released quarterly estimates of health insurance coverage from the National Health Interview Survey (NHIS) covering the second quarter (April – June) of 2024.
This blog post covers this newly released Q2 NHIS data, including relevant changes in health insurance coverage compared to the same period the year prior, April – June 2023. We also delve into coverage changes by various breakdowns, including by age, race and ethnicity, and poverty level.
NHIS Data Begin to Show Medicaid Unwinding Impact on Coverage
These newest data from the NHIS are some of the first from this survey to show significant changes in coverage coincident with the Medicaid unwinding (the state-level resumption of normal Medicaid eligibility redetermination procedures in April 2022 that had been put on hold during the COVID-19 public health emergency). We will continue to monitor quarterly NHIS early release data to track changes in coverage during the unwinding.
Changes by Age
Between Q2 2023 and Q2 2024, rates of uninsurance remained stable across all measured age groups, at:
-
7.6% among all ages
-
9.1% among the nonelderly (age 0–64)
-
4.6% among children (age 0–17), and
-
10.8% among nonelderly adults (age 18–64)
There were concurrent and offsetting changes in public and private coverage over the same period. Among the nonelderly population, public coverage fell 3.6 percentage points (PP) to 26.6%, private coverage rose 2.8 PP to 66.3, and Exchange-based private coverage rose 1.7 PP to 6.0%.
Among nonelderly adults, public coverage fell 3.7 PP to 21.1%, private coverage rose 3.2 PP to 70.3%, and Exchange-based private coverage rose 2.1 PP to 7.1%.
Among persons of all ages, only public coverage had a statistically significant change, falling 2.8 PP to 39.0%.
There were no statistically significant changes in coverage among children, and coverage remained statistically unchanged at 42.0%, 55.2% and 2.9% for public, private, and Exchange-based private coverage, respectively.
Changes by Race and Ethnicity (nonelderly adults)
Rates of health insurance coverage and uninsurance were statistically unchanged among all measured groups by race and ethnicity except for nonelderly, non-Hispanic White adults. Among that group, the share with public coverage fell 5.0 PP to 17.2%, the share with private coverage rose 3.8 PP to 77.6%, and the share uninsured was statistically stable at 7.5%.
Changes by Poverty Level (nonelderly population)
There were fewer statistically significant changes by poverty level among the nonelderly population compared to changes by age group.
Among those with incomes in the range of 100%–200% of the federal poverty level (FPL), the share who were uninsured increased 4.1 PP to 15.4%.
Public coverage fell among those with incomes above 400% FPL, decreasing 2.0 PP to 7.0%.
Rates of uninsurance were statistically unchanged across measured poverty level groups, and coverage rates also held steady among the 0–100% FPL, 100–200% FPL, and 200–400% FPL groups.
Notes
All changes and differences described were statistically significant based on two-sided t-tests at the 95% level of confidence, indicating that these changes were likely to reflect true changes in the population given the available data. Lack of statistically significant changes does not indicate certainty that there was no true population change, but rather that any true population change was not detectable with the available data.
The presented estimates represent the U.S. civilian noninstitutionalized population.

Race/Ethnicity Data in CMS Medicaid (T-MSIS) Analytic Files: 2022 Data Assessment
November 14, 2024:The Transformed Medicaid Statistical Information System (T-MSIS) is the largest national database of current Medicaid and Children’s Health Insurance Program (CHIP) beneficiary information collected from U.S. states, territories, and the District of Columbia (DC).1 T-MSIS data are critical for monitoring and evaluating the utilization of Medicaid and CHIP, which together provide health insurance coverage to almost 90 million people.2
Due to their size and complexity, T-MSIS data files are challenging to use directly for research and analytic purposes. To optimize these files for health services research, Centers for Medicare and Medicaid Services (CMS) repackages them into a user-friendly, research-ready format called T-MSIS Analytic Files (TAF) Research Identifiable Files (RIF). One such file, the Annual Demographic and Eligibility (DE) file, contains race and ethnicity information for Medicaid and CHIP beneficiaries.
This information is vital for assessing enrollment, access to services, and quality of care across racial and ethnic groups in the Medicaid/CHIP population, whose members are particularly vulnerable due to limited income, physical and cognitive disabilities, old age, complex medical conditions, unaffordable rents, and other social, economic, behavioral, and health needs.
To guide researchers and other consumers in their use of T-MSIS data, CMS produces data quality assessments of the completeness of race and ethnicity data along with other data such as enrollment, claims, expenditures, and service use. The Data Quality (DQ) assessments for race and ethnicity data have been posted for data years 2014 through 2022 and indicate varying levels of “concern” regarding race and ethnicity data completeness. Some data years have multiple data versions (e.g., Preliminary, Release 1, Release 2), each with their own DQ assessment.
While completeness of race and ethnicity data reported to CMS has historically remained inconsistent among the states, territories, and DC, SHADAC has been monitoring the quality of these data over time. We are encourage by an improvement in quality as discussed below. This blog explores not only the 2022 Data Release 1, the most recent T-MSIS race and ethnicity data for which a DQ assessment is available, but also a brief analysis of data quality trends over time that we plan to follow in future T-MSIS file releases.
Evaluation of T-MSIS Race and Ethnicity Data
DQ assessments for each year and data version of T-MSIS data are housed in the Data Quality Atlas (DQ Atlas), an online evaluation tool developed as a companion to T-MSIS data.3 The DQ Atlas assesses T-MSIS race and ethnicity data using two criteria: the percentage of beneficiaries with missing race and/or ethnicity values in the TAF; and the number of race/ethnicity categories (out of five) that differ by more than ten percentage points between the TAF and American Community Survey (ACS) data.
Taken together, these two criteria indicate the level of “concern” (i.e., reliability) for states’ T-MSIS race/ethnicity data. To construct the external ACS benchmark for evaluating T-MSIS data, creators of the DQ Atlas combine race and ethnicity categories in the ACS to mirror race and ethnicity categories reported in the TAF (see Table 1). More information about the evaluation of T-MSIS race and ethnicity data is available in the DQ Atlas’ Background and Methods Resource.
Five “concern” categories appear in the DQ Atlas: Low Concern, Medium Concern, High Concern, Unusable, and Unclassified.
States with substantial missing race/ethnicity data or race/ethnicity data that are inconsistent with the ACS – a premier source of demographic data – are grouped into either the High Concern or Unusable categories, whereas states with relatively complete race/ethnicity data or race/ethnicity data that align with ACS estimates are grouped into either the Low Concern or Medium Concern categories. The Unclassified category includes states for which benchmark data are incomplete or unavailable for a given data year and version.

Quality Assessment by State
Table 2 shows the Race and Ethnicity DQ Assessments for the 2022 TAF (Data Version: Release 1). The categorization criteria used to determine the levels of concern for the 2022 TAF Release 1 data are the same as those used to assess T-MSIS data from previous years and versions. 15 states received a rating of “Low Concern.” There were 22 states (including Puerto Rico [PR]) that fell into the “Medium Concern” category.
Most of the “Medium Concern” states (17 of 22) fell into the subcategory denoting the higher percentage range of missing race/ethnicity data (from 10% up to 20%). A similar pattern can be seen among the “High Concern” states, most of which (10 of 14) fell into the subcategory denoting the highest percentage range of missing race/ethnicity data (from 20% up to 50%).
Finally, 14 states (including DC) received a rating of “High Concern.” One state (Utah) received an “Unusable” rating, meaning it was missing at least 50% of race/ethnicity data. The Virgin Islands (VI) is the only state/territory categorized as “Unclassified” in the 2022 TAF (Data Version: Release 1) due to insufficient or incomplete data, and does not appear in Table 2.
Table 2. Race and Ethnicity Data Quality Assessment, 2022 T-MSIS Analytic File (TAF) Data Release 1
Notes: *T-MSIS includes all 50 states, the District of Columbia (DC), and the U.S. territories of Puerto Rico (PR) and the Virgin Islands (VI). However, a DQ assessment is not available for VI in the 2022 TAF (Data Version: Release 1) due to incomplete/unavailable data.
Despite ongoing variation in the completeness of race and ethnicity data reported to CMS, SHADAC researchers have noted a trend toward better quality data overall, although the results in 2022 were somewhat more mixed.
Since beginning to track these quality assessments with the 2019 T-MSIS TAF release, several states have shifted up the quality assessment scale. The number of states with data of “High Concern” increased from 2021 to 2022. This primarily reflects two states (Massachusetts and Tennessee) moving from the “Unusable” category up to the “High Concern” category, which means they are reporting race and ethnicity data, even if it is of questionable quality.
Specifically, 2022 race/ethnicity TAF data from 14 states received a rating of “High Concern” compared to 11 states’ data in 2021 and 16 states’ data in 2020. The number of states with “Unusable” data has also dropped each year – 1 state’s 2022 race/ethnicity TAF data was classified as “Unusable” compared to 3 states’ data in 2021 and 4 states’ data in 2020.
Visualizing T-MSIS Data in the DQ Atlas
The DQ Atlas enables users to generate maps and tables that compare the quality of T-MSIS data between states across different topics, such as race/ethnicity, age, income, and gender (see Figure 1).
Visualizing T-MSIS data in this manner can help researchers quickly assess the completeness of a single variable as well as the relative completeness (or incompleteness) of certain variables compared to others. For example, in the 2022 TAF Data Release 1, all states and territories received a “Low Concern” rating for age data, whereas only 30 states and territories received a “Low Concern” rating for income.

Looking Ahead
Increasingly, a wide diversity of voices, from non-profits and health insurers to state-based marketplaces and policymakers, have called for improving data collection of race, ethnicity, and language data, often with the goal of advancing health equity. CMS’s efforts to improve the quality and availability of T-MSIS data reflect this nationwide movement toward data collection practices that more accurately capture the diversity of the U.S. population.
SHADAC was excited to see the revised Office of Management and Budget (OMB) standards related to the collection of race and ethnicity data. The proposed revisions align with available evidence, are consistent with the changes made by leading states, and, most importantly, explicitly state that these standards should serve as a minimum baseline with a call to collect and provide more granular data.
However, while these standards are specifically named as minimum reporting categories for data collection throughout the Federal Government, if adopted, they are likely to shape data collection and reporting across all sectors, including the states that collect race/ethnicity data through the Medicaid application process.
Many states express difficulties reporting data, as there is misalignment in how state eligibility systems, Medicaid Management Information System (MMIS), and T-MSIS format race and ethnicity data. Before states submit data to T-MSIS, they must reformat and aggregate data, which may affect the quality of submitted data.
One approach to improve the collection and reporting of data is providing states with an updated model application using evidence-based approaches to race and ethnicity questions that improve applicant response rate and data accuracy.

Children’s Health Insurance in 2023: Exploring Rising Uninsured Rates for Low-Income Children
October 21, 2024:
This post is a part of our Survey Data Season series where we examine data from various surveys that are released annually from the summer through early fall. Find all of the Survey Data Season series posts on our Survey Data Season 2024 page here.
With the recent release of survey data from both the American Community Survey (ACS) and the Current Population Survey (CPS), SHADAC researchers have begun delving into what this data can tell us about health insurance coverage in 2023 for:
- The total U.S. population
- Nonelderly adults (age 19-64), and
- Children (age 0-18)
As seen in our full blog post on the 2023 ACS data release and our blog & infographic on the 2023 CPS data release, we found that overall rates of public coverage and private coverage remained unchanged in 2023. However, it is important to note that alongside that indicator of coverage stability at a national level, we also found that:
- Changes in uninsured rates for nonelderly adults' (age 19-64) varied depending on Medicaid expansion status and poverty level
- Rates of uninsured children (age 0-18) rose significantly
These findings sparked questions: After two years of falling rates, what could be contributing to rising uninsurance among children? Changes in nonelderly adults’ uninsured rates between 2022 and 2023 varied by poverty level and the status of Medicaid expansion in their state – could either of these factors also be impacting children’s uninsured rates in the newly released data?
While more research into causes behind these changes is needed, SHADAC began by looking at the ACS HI-11 tables, which include data specific to health insurance coverage rates for children below 200% of the Census poverty threshold.
Keep reading to see some of our findings on how the insurance coverage of low-income children (those with family incomes below 200% of the Census poverty threshold) changed between 2022 and 2023 both nationally and at the state level.
Nationally, Children’s Uninsured Rates Increased while Public Coverage Rates Decreased
Looking at 2023 ACS data for children below 200% of the Census poverty threshold, we found that uninsured rates for this group mirrored overall trends at a national level, rising by 0.4 percentage points (PP) to 7.3%. This significant increase was likely driven by a 0.6PP decrease in public coverage (bringing that national rate down to 72.6%) and a statistically unchanged rate of private coverage (27.0%).
Further, low-income children’s uninsured rate was 1.9PP higher than the 5.4% rate of uninsured children overall, a statistic which saw its own significant rise from 5.1% in 2022.
State-Level Coverage Changes for Low-Income Children
When we delve into state-level data for low-income children, we see that Louisiana (+1.5PP), Michigan (+1.2PP), South Carolina (+1.6PP), and Texas (+1.5PP) all saw significant increases in uninsurance, rising to 5.5%, 4.3%, 8.0%, and 15.4%, respectively.
As with the national uninsured rate, our analysis found that a couple of these states mirror a simultaneous decrease in public coverage that likely influenced the increase in uninsurance. For example, Michigan saw a 3.1PP decrease in public coverage, bringing it down to 73.2%, and Texas saw a 2.5PP decrease in public coverage, bringing it down to 65.0%.
Again, similar to trends at the national level, none of the states that saw increased uninsurance for low-income children saw any significant changes in private coverage among that group.
No states saw decreases in uninsurance.
Looking Closer at Public & Private Coverage Rates for Low-Income Children
Looking at public coverage, states saw a wide range of changes:
- Four states, Arkansas (-4.8PP ), Michigan (-3.1PP), Nebraska (-5.4PP), and Texas (2.5PP), saw significant decreases in public coverage.
- Kansas (+4.5PP), Tennessee (+3.2PP), and Wyoming (+15.8PP) saw significant increases in public coverage
Looking at private coverage, states also saw a wide range of changes:
- Alaska (-8.1PP), Kansas (-5.3PP), Tennessee (-3.8PP), and Wisconsin (-4.9PP) all saw decreases in private coverage
- Kentucky (+3.4PP), Nebraska (+6.5PP), and New York (+2.5PP) all saw increases in private coverage
One thing to note here is that Nebraska, the state with the largest significant decrease in public coverage for low-income children, did not appear on the list of states with significant increases in uninsurance for the same group. But it did also see the largest increase in private coverage for this group, which could have mitigated any change in uninsurance.
Conclusion & Discussion
By looking deeper into low-income children’s health insurance coverage in 2023, we hoped to find more information on why uninsured rates have increased both overall and specifically for this group.
At the national level and in a small number of states, we observed increases in uninsurance that coincided with decreases in public coverage. This could be a result of the unwinding of the Medicaid continuous coverage requirement that began during 2023. According to an issue brief on children’s poverty and health insurance coverage published by KFF in January 2024, Medicaid covers 8 in 10 children living in poverty. This brief goes on to report that based on reported unwinding data from 23 states, almost 4 in 10 of those disenrolled from Medicaid during the unwinding are children, likely impacting the many children living in poverty with this public coverage.
However, this story of falling public coverage and rising uninsurance was not consistent across the states. We did not observe significant changes in uninsurance in most states, either because decreases in one type of coverage were offset by increases in another type of coverage, or because there was little movement in coverage overall.
Coverage estimates for 2024 (to be released next fall) will give a more complete picture of coverage during the unwinding and may clarify how coverage evolved during this dynamic period.

About the American Community Survey (ACS)
The ACS is a household survey that began in 2005 and produces annually updated data on a variety of population characteristics, including health insurance coverage. In total, the ACS surveys approximately three million U.S. households each year. An important feature of the American Community Survey is that it includes a large enough sample for state‐level and sub‐state estimates.
The ACS began asking survey respondents about health insurance coverage during the 2008 calendar year. Specifically, the survey asks respondents about current coverage for each person in the respondent’s household. A person is categorized as “insured” if he or she has coverage at the point in time at which the survey is administered.
*Why Aren’t Estimates Provided for All Counties?
Due to sample size constraints, single-year ACS estimates are available at the county level only for counties with a population greater than 65,000.
How Are These Estimates Different from the Estimates that SHADAC Publishes Using Census Bureau Micro-Data Files?
Two definitions used by the Census Bureau to generate the tabulations above differ from those that SHADAC uses to generate tabulations for State Health Compare. The definitional differences are as follows:
Family
The Census Bureau defines a family as “all related people in a household.”
SHADAC defines a family using a measure called the “Health Insurance Unit” (HIU), which includes all individuals who would likely be considered a family unit in determining eligibility for either private or public coverage.
To learn more about the 2020 update of SHADAC's Health Insurance Unit (HIU) see our HIU resource page, which houses two issue briefs: The first brief describes the SHADAC HIU, its purpose, the most recent update, and improvements to HIU data inputs; the second brief outlines the impacts of using the SHADAC HIU in analysis so that researchers can assess whether the SHADAC HIU is suitable for their research and what the potential impacts of its use might be. The page also provides a link to STATA and SAS codes to aid in the use of the HIU variable.
Family Income
The Census Bureau determines family income as a percentage of the Federal Poverty Level (FPL), which is a definition of poverty used primarily for statistical purposes. For example, FPL is used to estimate the number of Americans living in poverty each year.
SHADAC determines family income as a percentage of the U.S. Department of Health and Human Services’ Federal Poverty Guidelines (FPG), which is a measure used for administrative purposes. For example, FPG is used to determine eligibility for federal programs such as Medicaid and the Supplemental Nutrition Assistance Program (SNAP).
To learn more about the difference between FPL and FPG, read our updated FPL and FPG blog post from April 2024.

2023 ACS: After Two Years of Decline, Uninsured Rates Increased for Children; Public and Private Coverage Rates See Variations Across the States
September 30, 2024:
This post is a part of our Survey Data Season series where we examine data from various surveys that are released annually from the summer through early fall. Find all of the Survey Data Season series posts on our Survey Data Season 2024 page here.
The U.S. Census Bureau released 2023 health insurance coverage estimates from the American Community Survey (ACS) yesterday, September 12, 2024. These estimates include both national- and state-level information about health insurance coverage by type, as well by certain demographic categories.
Overall, 2023 ACS data and findings at the national level echoed those from the Current Population Survey (CPS ASEC), which was released this past Tuesday, September 10, 2024. According to new ACS data, among the total U.S. population, the 7.9% uninsured rate in 2023 remained statistically unchanged from the previous year (8.0%).
Also like the 2023 CPS data, the newly released ACS data show a significant increase in the uninsured rate among children (age 0-18) in 2023, rising to 5.4% from 5.1% in 2022.
The rest of the blog will walk through state-level findings regarding different types of health insurance coverage (public, private, and uninsurance) in 2023. We will also discuss changes by age category for nonelderly adults (age 19-64) and children (age 0-18).
Key Findings from the 2023 ACS by Health Insurance Coverage Types
Uninsurance
The stability of the national uninsurance rate from 2022 to 2023 was supported by little change among the states between these two years as well.
The uninsured rate fell in 11 states, and increased in Iowa, New Jersey, and New Mexico. North Dakota saw the largest decrease in uninsurance at 1.9 percentage points (PP), moving from 6.4% in 2022 to 4.5% in 2023. New Mexico saw the largest percentage point increase in uninsurance at 0.9 PP, rising from 8.2% in 2022 to 9.1% in 2023. Across the states, Texas and Massachusetts continued their long-running trend as the states with the highest and lowest rates of uninsurance, at 16.4% and 2.6%, respectively.
Private Coverage
2023 ACS data show that rates of private coverage fell slightly to 67.0% in 2023 from 67.2% in 2022. Rates of employer-sponsored insurance coverage (ESI) and direct purchase coverage were unchanged at 54.7% and 13.9%, respectively.
Private insurance coverage rates decreased in nine states in 2023, and increased in four - Florida, North Dakota, Texas, and West Virginia. Delaware saw the largest decrease in private coverage with a 2.7PP decrease from 71.8% in 2022 to 69.1% in 2023. North Dakota saw the largest increase in private coverage, rising 2.4PP from 78.4% in 2022 to 80.8% in 2023. Rates of private coverage across the states ranged from a high of 80.8% in North Dakota to a low of 54.1% in New Mexico.
Public Coverage
Nationally, the rate of public insurance coverage rose significantly in 2023, increasing to 37.4% from 37.2% the previous year. Surprisingly, the rate of Medicaid coverage was unchanged at 21.3% (21.2% in 2022), while the rate of Medicare coverage rose to 18.8% in 2023 from 18.5% the year prior.
Public coverage saw the most change of all insurance types across the states in 2023, increasing in 13 and decreasing only in Arkansas, Idaho, Texas, and West Virginia. Arkansas saw the largest decrease in public coverage, falling by exactly 2.0PP from 45.0% in 2022 to 43.0% in 2023. Wyoming experienced the largest increase in public coverage, rising also by exactly 2.0PP from 31.2% in 2022 to 33.2% in 2023. Across the states, rates of public coverage ranged from a high of 52.2% in New Mexico to a low of 22.6% in Idaho in 2023.
Key State-Level Findings from the 2023 ACS by Age: Nonelderly Adults (19-64)
Uninsurance
The uninsured rate among nonelderly adults decreased 0.3PP from 11.3% in 2022 to 11.0% in 2023, representing the third year of falling uninsured rates for this group. Twelve states saw decreases in their uninsured rates while only Connecticut, Iowa, New Jersey, and Ohio saw increases in their uninsured rates. As with the overall population, North Dakota saw the largest decrease in uninsured rates among nonelderly adults, decreasing 2.2PP to 6.1% in 2023. Iowa saw the largest increase in uninsured rates, rising 1.0PP to 7.1% in 2023.
Private Coverage
The rate of private coverage among nonelderly adults was unchanged at 73.5% in 2023 (73.4% in 2022). Across the states, nearly the same number experienced increases (eight) in private coverage rates for nonelderly adults as experienced decreases (six). North Dakota had the largest increase at 3.3PP, with private coverage rates rising to 85.1% in 2023 from 81.8% in 2022. Delaware saw the largest decrease at 2.3PP, with private coverage rates falling to 74.0% in 2023 from 76.3% in 2022.
Public Coverage
The rate of public coverage among nonelderly adults was also unchanged in 2023, holding steady at 19.5% (19.4% in 2022). Looking at the states, this rate stability was supported by a nearly equal number of states that experienced increases (six) as did those that experienced decreases (five). Delaware had the largest increase in public coverage, rising 2.1PP to 21.4% in 2023 from 19.3% in 2022. Arkansas had the largest decrease in public coverage, falling by 2.1PP to 24.1% in 2023 from 26.2% in 2022.
Key State-Level Findings from the 2023 ACS by Age: Children (0-18)
Uninsurance
The uninsured rate among children rose 0.3PP to 5.4% in 2023 from 5.1% in 2022. This change represents the first year of increased uninsurance among children after two years of falling rates. Five states saw an increase in their uninsured rate while three states — Colorado, Kentucky, and North Dakota — saw a decrease in their uninsured rate. As with nonelderly adults, North Dakota had the largest decrease in uninsured rates for children, falling 1.9PP from 5.5% in 2022 to 3.6% in 2023. New Mexico saw the largest increase in uninsurance, rising 2.1PP from 3.8% in 2022 to 5.9% in 2023. Rates of uninsurance among children ranged from a low of just 1.3% in the District of Columbia to a high of 11.9% in Texas.
Private Coverage
The rate of private coverage among children in 2023 was 60.6%, unchanged from the same recorded rate in 2022. Nearly as many states — Florida, Illinois, Maryland, and West Virginia — saw increases in rates of private coverage as those that saw decreases — New Mexico, Ohio, Pennsylvania, Tennessee, and Wyoming — from 2022 to 2023. West Virginia has the largest increase in private coverage, rising 4.8PP to 57.3% while Wyoming had the largest decrease in private coverage, falling 6.4PP to 65.2%.
Public Coverage
The rate of public coverage among children in 2023 was 39.4%, statistically unchanged from the previous year at 39.6%. Five states — Iowa, Missouri, New Mexico, Tennessee, and Wyoming — saw an increase in public coverage while seven saw a decrease in public coverage. Wyoming had the largest increase in public coverage, rising 9.5PP to 33.6% while West Virginia had the largest decrease in public coverage, falling 5.0PP to 46.0% in 2023.

Concluding the Continuous Coverage Requirement and the Medicaid Unwinding
The continuous coverage requirement that prevented states from terminating individuals’ Medicaid coverage during the COVID-19 pandemic ended on March 31, 2023. The resumption of Medicaid eligibility redeterminations and renewals (and potential disenrollments), a process commonly referred to as the “unwinding,” began on April 1, 2023 and has since ended on June 30, 2024.
Each state was given a 14-month period to navigate returning to normal operations while also meeting reporting requirements set by the Centers for Medicare & Medicaid Services (CMS), such as submitting monthly “Unwinding Data Reports,” in order to publicly share coverage transitions and outcomes data during this time. Though the unwinding period has come to a close, a May 30, 2024, State Health Official (SHO) letter announced that CMS will extend these requirements for the foreseeable future. Beginning on July 1, 2024, all states are expected to continue to submit certain metrics contained in the Unwinding Data Report, now referred to as an “Eligibility Processing Report,” on an ongoing basis.
For more information on the post-unwinding period and reporting process, see a recent blog written by SHADAC researchers for State Health & Value Strategies:
Unwinding Ends, but States’ Reporting of Medicaid Renewal Data Continues (SHVS Cross-Post)
It is important to note that full-year 2023 estimates from all surveys, including the ACS and CPS, will not be fully reflective of a Medicaid unwinding process that began mid-year. However, provisional data from sources like the Census Bureau’s Household Pulse Survey, can give us an indicator of coverage trends during this time.

Upcoming Webinar: U.S. Census Bureau Data Explained: Breaking Down 2023 Health Insurance Coverage Estimates from the ACS & CPS - featuring a Q&A with a Census Bureau Expert
On Thursday, September 26th at 1:00 PM CST, SHADAC will host a webinar covering the release of new Census data on health insurance coverage estimates for 2023. The estimates come from two key federal surveys conducted by the U.S. Census Bureau: The American Community Survey (ACS) and the Current Population Survey (CPS).
SHADAC researchers and presenters Robert Hest and Andrea Stewart will discuss the 2023 health insurance data at national and state levels, as well as by coverage type, and a range of other demographic categories (age, geography, poverty level, and more).
In addition, SHADAC will walk through how to access the data and examples of how to use it to answer research questions. We are also pleased to once again welcome a special guest from the Census Bureau, Sharon Stern, who will join us to answer questions from attendees after the presentation.
