Unrecognized COVID-19 Deaths: A Study Reveals Significant Undercounting in the U.S.

Overview of the Findings
A recent study published in *Science Advances* estimates that the official COVID-19 death toll in the United States from March 2020 to December 2021 is significantly underreported. While the Centers for Disease Control and Prevention (CDC) recorded approximately 840,000 deaths during this period, researchers from Boston University and other institutions suggest that nearly 155,000 additional deaths, or about 19%, went unrecognized. This undercounting disproportionately affected minority and economically disadvantaged communities.
Methodology and Key Insights
The researchers employed a machine learning model to analyze 5.7 million death records of adults aged 25 and older. By training the model on hospital deaths, where testing was nearly universal, they predicted the likelihood of COVID-19 being the cause of deaths that occurred outside hospital settings. The study found that unrecognized deaths were often attributed to conditions like Alzheimer's disease, cardiovascular disease, or diabetes, masking the true impact of the virus.
Demographic Disparities
The study highlights that the unrecognized deaths were more prevalent among Hispanic individuals, older adults, and those with lower socioeconomic status. Specifically, the likelihood of uncounted deaths was highest in states such as Alabama, Oklahoma, and South Carolina. The researchers noted that these findings reflect systemic inequities in the U.S. death investigation system, which may have led to biased reporting and undercounting.
Official Responses and Context
Andrew Stokes, a senior author of the study, emphasized the need for improved death investigation systems to ensure accurate mortality data in future public health crises. He stated, “If we improve death investigation systems and the quality of our national death surveillance data, we'll be much better prepared to detect the next pandemic earlier and more fully.”
Criticism of Current Reporting Practices
The study's findings have reignited discussions about the accuracy of COVID-19 death counts, which have been politically contentious. Critics argue that the existing death investigation system is antiquated and lacks the necessary training for coroners, leading to discrepancies in how deaths are recorded. Some families reportedly pressured coroners not to attribute deaths to COVID-19, further complicating accurate reporting.
Broader Implications
The researchers concluded that the communities affected by the undercounting of COVID-19 deaths could be interpreted as a pattern of structural racism, classism, and ableism within the death investigation system. They called for further research and policy attention to address these disparities and improve the accuracy of death reporting in the future.
Verbatim Quotes
- “This study indicates that the US death investigation system reported COVID-19 deaths in a systematically inequitable way that hid the true extent of pandemic mortality and inequities,” — Andrew Stokes, PhD, Boston University
- “the communities affected by the undercounting of COVID-19 deaths could be interpreted as a pattern of structural racism, classism, and ableism in the death investigation system that warrants further research and policy attention.” — Study Authors
This study underscores the importance of accurate mortality data in understanding the full impact of the COVID-19 pandemic and highlights the need for systemic changes to ensure equitable health outcomes for all communities.
