COVID-19 Vaccination Rates: State-level and Subpopulation Evidence from the Household Pulse Survey
July 19, 2021:Update 6: June 9 to June 21
The COVID-19 vaccines promise to help protect individual Americans against infection and eventually provide population-level herd immunity. After several months of rolling out the various one and two-shot COVID-19 vaccines, which have included hiccups from the Johnson & Johnson vaccine, vaccination rates continue to increase at a slow but steady pace. Although the country fell short of meeting the current administration’s goal of vaccinating 70% of the adult population by July 4 (as measured by official administrative data reported to the Centers for Disease Control [CDC]), several states have achieved this goal.
Over the past several months, all states have increased COVID-19 vaccine rollout by expanding vaccine access to the general adult population and children over 12. However, there are still concerns on prioritization decisions and the existing mechanisms of the vaccine rollout—in addition to evidence that lower-income individuals, people of color, and individuals without strong connections to the health care system are less likely to get vaccinated—which have created challenges in equitable distribution of the COVID-19 vaccine and could worsen existing pandemic-related health inequities.
The available data have not assuaged these concerns, and show patterns of lower vaccination rates among people with lower levels of education, no health insurance coverage, and marginalized racial and ethnic groups. The U.S. Census Bureau recently released updated data on take-up of COVID-19 vaccines from its Household Pulse Survey (HPS), collected June 9-21, 2021. The HPS is an ongoing, biweekly tracking survey designed to measure impacts of the COVID-19 pandemic. These data provide an updated snapshot of COVID-19 vaccination rates and are the only data source to do so at the state level by subpopulation.
This blog post presents top-level findings from these new data, focusing on rates of vaccination (one or more doses) among U.S. adults (age 18 and older) living in households and comparing to results from the last half of March, the most recent time period of comparison from this ongoing blog series.
These data represent the latest release from Phase 3.1 of the HPS, which has a biweekly data collection and dissemination approach. The Census Bureau has indicated that it plans to continue administering the survey through December 2021.
Nationally, over three-fourths of adults had received a vaccination, but this varied by state
According to the new HPS data, 79.1% of U.S. adults had received one or more COVID-19 vaccinations towards the end of June1, though this varied by state from a low of 63.9% in Mississippi to a high of 91.0% in Massachusetts. At least four in five adults had received a vaccine in 22 states and the District of Columbia.
Vaccination rates increased considerably across all states; states with lower rates catching up
Nationally, adult vaccination rates substantially increased from the last half of March, rising from 47.0% during March 17-29, 2021, to 79.1% during June 9-21, 2021. Many states experienced large increases in their vaccination rates. The size of these increases varied from an 11.2 percentage-point (PP) increase in North Dakota to a 46.1 PP increase in Massachusetts. Five states saw increases of 40.0 PP or larger: Maryland, Massachusetts, Oregon, Rhode Island, and Vermont.

Disparities in vaccination rates improved, but slowly and unevenly
Although there have been ongoing strategies to achieve health equity in COVID-19 vaccine rollouts, vaccination rates continued to vary to a great degree by demographic and socioeconomic factors. Gaps in vaccination compared to the national average narrowed slightly for most groups, though some saw larger improvements. As with previous iterations in this blog series, vaccination rates were lower for certain subpopulations such as Black adults, adults who identified as “Some other race/Multiple races,” adults without a high school education, and adults without health insurance coverage. More resources, attention, or new strategies may be needed to close the gaps for these hardest-to-reach groups.
Asian and White adults continued to have above-average vaccination rates at 94.6% and 79.5%, respectively. Rates among Black adults (71.9%) and adults identifying with “Two or more” (Multiple) or “Some other” race (68.5%) continued to be below the national average. Rates among Hispanic/Latino adults improved, and are now above the national average at 79.6%. Hispanic/Latino adults also saw the largest improvement relative to the national average, going from almost 20 percent below the national average in late March (37.9% vs. 47.0%) to nearly one percent above the national average in June (79.6% vs. 79.1%).
Percent of Adults Who Had Received a COVID-19 Vaccine by Race/Ethnicity, 2021
Disparities by education level remained, with adults holding a bachelor’s degree or higher continuing to have the highest vaccination rate at 90.8%, and adults without a high school diploma having the lowest vaccination rate at 68.6%. Despite having the lowest vaccination rate, adults without a high school diploma had the largest relative improvement to the national average, going from 38 percent below the national average in March (29.2% vs. 47.0%) to 13 percent below the national average in June (68.6% vs. 79.1%). Vaccination rates among adults with a high school degree or equivalent and adults with some college or an associate’s degree also improved somewhat relative to the national average.
Adults with health insurance coverage had an above-average vaccination rate at 82.4%, while uninsured adults had a below-average vaccination rate at 61.4%. Regardless of having a rate substantially below the average, the rate among those not covered by any type of health insurance had a notable improvement relative to the national average, going from 50 percent below the national average in March (23.7% vs. 47.0%) to 22 percent below the national average in June (61.4% vs. 79.1%).

Notes about the Household Pulse Survey Data
The estimated rates presented in this post were pulled from the HPS COVID-19 Vaccination Tracker published by the Census Bureau. Though these counts are accompanied by standard errors, standard errors are not able to be accurately calculated for rate estimates. Therefore, we are not able to determine if the differences we found in our analysis are statistically significant or if the estimates themselves are statistically reliable. Estimates and differences for subpopulations at the state level should be assumed to have large confidence intervals around them and caution should be taken when drawing strong conclusions from this analysis. However, the fact that these indications of COVID-19 inequities mirror patterns of other vaccinations inequities demonstrate reason for concern.
Though produced by the U.S. Census Bureau, the HPS is considered an “experimental” survey and does not necessarily meet the Census Bureau’s high standards for data quality and statistical reliability. For example, the survey has relatively low response rates (6.4% for June 9-21), and sampled individuals are contacted via email and text message, asking them to complete an internet-based survey. These issues in particular could be potential sources of bias, but come with the tradeoffs of increased speed and flexibility in data collection as well as lower costs. A future post will investigate differences between COVID-19 vaccination rates estimated from survey data (such as the HPS) and administrative sources. The estimates presented this post are based on responses from 68,067 adults. More information about the data and methods for the Household Pulse Survey can be found in a previous SHADAC blog post.

1 Note that it is not unusual for there to be appreciable differences between survey-based estimates and those derived from administrative data, as there are here between the vaccination rates observed in the HPS and those seen in CDC administrative vaccination data. There could be several reasons for these differences, including differences in the population universe (i.e., household-residing adults vs. total adult population), differences in the measured time period, the inaccuracies between self-reported vs. administratively collected data, and differences in the representativeness of survey vs. administrative data. Although administrative data are often thought to be more accurate than survey-based estimates, survey data such as the HPS have the advantage of providing more granular detail about the demographic and socioeconomic characteristics of populations of interest that are often unavailable or incomplete in administrative data.

New Study Shows Heightened Mental Health Burdens for Young Adults, Adults with Lower Incomes or Lower Education Levels, and Adults who Experienced Income Loss during the COVID Pandemic
July 1, 2021:As rates of COVID vaccination increase around the world and the nation, attention is beginning to turn toward addressing more of the non-physical impacts and effects of the virus, such as the mental health burdens borne by large segments of the population.1
In a new issue brief released this week, SHADAC researchers used the U.S. Census Bureau’s Household Pulse Survey to study the relationship between the COVID-19 pandemic and mental health burdens for the United States’ adult population. Based on data gathered in April/May through December of 2020, the brief’s authors found that reported rates of combined and individual symptoms of anxiety and depression in the first part of the year were more than triple when compared with data from a similar time period in a related survey, the Center for Disease Control and Prevention’s (CDC) National Health Interview Survey (NHIS). The HPS found a rate of 35.9 percent of adults reporting anxiety or depression symptoms in April/May 2020, versus 11.0 percent from the NHIS in January-June 2019.2 And rates only continued to grow significantly throughout the remainder of 2020, reaching a peak of 41.9 percent in December.
In particular, the analysis found that the highest rates of these mental health burdens were borne by younger adults, adults with less than a high school education, adults with lower incomes, and adults who experienced or anticipated job-related income loss. In each case, reported rates of anxiety or depression symptoms were significantly higher than those for the total population (41.9 percent).
In December 2020…
…younger people consistently reported the highest rates of anxiety or depression, with more than half (56.4 percent) of 18-29 year-olds reporting symptoms of anxiety or depression, a significantly higher rate than this same group reported in April/May 2020.
…roughly one-half (51.2%) of adults with less than a high school education reported anxiety or depression symptoms.
…more than half (58.2 percent) of adults with household incomes of less than $25,000 reported anxiety or depressions symptoms, a statistically significant increase over their April/May 2020 rate.
The HPS also collected data on anxiety and depression symptoms from adults who had either experienced or anticipated a job-related income loss during the 2020 year. Just over one-half of individuals (53.2 percent) who had experienced an employment income loss reported symptoms of anxiety or depression, which was significantly higher than the roughly one-third (31.5 percent) rate among people who hadn’t experienced such a loss. An even greater number of people who anticipated an employment income loss (58.0 percent) reported anxiety or depression symptoms, which was again significantly higher than the approximately one-third (35.0 percent) rate among people who didn’t anticipate such a loss.
The pandemic's toll on mental health, especially for younger adults, has become increasingly worrisome in recent months.3 Mental health burdens, such as suicide deaths, were already an area of concern prior to COVID, with rates trending upward in the years before 2020.4
It is important for policymakers, as they consider directing resources toward addressing the impacts of COVID-19 on their individual populations, to understand which groups (i.e., younger adults, adults with lower incomes and education levels, and adults who experienced income losses) might benefit most from outreach to connect them with or increase their access to mental health care services.

2 The pandemic-era rates from the CDC study and the HPS are not perfectly comparable to the pre-pandemic rates from the NHIS because they come from different surveys with different methodologies. However, since they ask essentially the same questions on anxiety and depression, the rates should presumably be similar, so the substantially higher estimates in the pandemic-era surveys provide reason for concern.

COVID-19 Pandemic Coincided with Elevated and Increasing Anxiety and Depression Symptoms
SHADAC Director Dr. Lynn Blewett and SHADAC Researchers Colin Planalp and Robert Hest used data from the U.S. Census Bureau’s Household Pulse Survey (HPS) to study rates of anxiety and depression in the U.S. adult population for the months of April to December 2020.
The brief looks at both combined and individual rates of reported anxiety and depression symptoms for the total adult population as well as by specific breakdowns, including age, gender, race/ethnicity, income and education levels, and employment status.
Designed to provide near-real-time estimates of the economic, financial, and health impacts of the pandemic, the HPS asks questions covering topics such as health insurance coverage, medical treatment, employment status, and job loss, food security, and transportation access, among others. The HPS questions used in the analysis of this brief were adapted by the Census Bureau from a four-item screening tool commonly used by health care providers to identify symptoms of anxiety and depression.
Though the United States is beginning to emerge from the darkest days of the pandemic, it is important to remember that this crisis affected not only physical health, but mental health as well, and these burdens must be continued to be monitored and addressed at the local, state, and national levels. This brief provides an overview of mental health impacts on different portions of the populations, and highlights which groups may benefit from particular outreach to connect them with needed mental health care.
