This is an extremely important and complex topic. Based on multiple primary sources, peer-reviewed research, and fact-checking organizations I have compiled, let me organize this from multiple angles.
🔍 Confirmation of Facts: What Actually Happened
📊 Is the Data Real?
→ YES. The data itself exists and is serious.
The most surprising aspect of excess mortality in 2021 was that it occurred in younger populations. Companies providing group life insurance began noticing this trend from Q3 2021 onward, with OneAmerica announcing a 40% increase in death claims in its group life insurance business for ages 18-64.
In fall 2021, while COVID-19-related deaths were declining, an abnormal and sudden increase in working-age mortality occurred. In Q3 2021, deaths among workers aged 35-44 exceeded baseline data from the three years before the pandemic by 101%, meaning approximately doubling. For two other age groups, mortality rates exceeded predictions by 79%.
An early 2023 SOA (Society of Actuaries) report revealed a wave of deaths where mortality for insured persons under age 45 in Q3 2021 exceeded pre-pandemic baseline values by 80%.
This research series revealed that during the pandemic, the "actual/expected mortality ratio" for working-age Americans exceeded that of older adults, and that excess mortality from all causes increased simultaneously with increases in COVID-19 deaths.
🏦 On Insurance Company Motivation
The core of the question—"insurance companies are driven by profit and loss"—is extremely important.
- Insurance companies are the payers of death benefits; if mortality increases, they lose money.
- They have no motive to hide increased mortality and instead have a strong incentive to accurately grasp and report it.
- Some insurance companies experienced the largest insurance payouts in history during Q3 and Q4 2021, with combined factors resulting in larger-than-expected losses. Q3 2021 saw high excess mortality among working-age populations, and quarterly death insurance claims for working-age adults reached an all-time record.
- According to the American Council of Life Insurers (ACLI), life insurance death benefits paid in 2021 reached approximately $100.19 billion (approximately 14 trillion yen), reaching an all-time high.
In other words, data credibility should be rated as high.
⚖️ What Do We Know About the Causes (and What Is Contested)
This is the most important and sensitive part. "The data is real" and "interpretation of its causes" are separate issues.
✅ Points Where Scientific Consensus Is Relatively Clear
The excess mortality among working-age adults from 2021-2022 was caused by COVID-19 and other factors, not by vaccination—this is the mainstream medical view.
Multiple factors appear to have worked in combination:
- Direct Impact of COVID-19 Delta Variant:
Relative mortality rates for the US working-age population in certain regions nearly doubled in Q3 2021, with unvaccinated individuals most vulnerable to the Delta variant's high lethality.
- Sharp Increase in Drug Overdose Deaths:
In 2021, drug overdose deaths exceeded 100,000 for the first time, setting a record (14% increase from 2020).
For the 35-44 age group, drug overdose deaths increased by over 35% during the pandemic.
- Delayed Medical Access and Reduced Medical Visits:
Not directly caused by COVID-19, but heart disease deaths increased by 3% and stroke deaths by 6%, and many such mortality changes are "almost certainly pandemic-related."
- Increase in Gun Violence and Traffic Accidents:
Data show that drug overdoses, gun violence, motor vehicle accidents, and preventable cardiovascular-metabolic diseases primarily drove excess mortality centered on working-age populations over the long term.
⚠️ Points Remaining Unexplained or Under Dispute
The SOA (Society of Actuaries) report concluded that "COVID-19 claims alone cannot completely explain the increase," and the full picture of causation has not yet been completely clarified.
According to the SOA report, the 35-44 age group showed "the highest cumulative actual/expected ratio during the pandemic period" and "the highest non-COVID excess mortality rate."
🧭 How Should We Evaluate This Report: A Comprehensive View
| Perspective | Evaluation |
|---|---|
| Data Reliability | ✅ High (reported by the side losing money; no motive to hide) |
| Seriousness of the Phenomenon | ✅ Real crisis (confirmed by CDC and academic research) |
| COVID-19 as Primary Cause | ✅ Certain to be a major factor |
| Drug and Social Factors | ✅ Established as significantly contributing in combination |
| Vaccine as Cause Claim | ❌ No scientific evidence at present (denied by FactCheck, CDC, etc.) |
| Complete Explanation of Non-COVID Factors | ⚠️ Still an ongoing research question |
💡 Conclusion
The insurance company's report, as data directly tied to profit and loss, represents evidence with minimal distortion, and the fact that "labor-age mortality rates rose abnormally in 2021" is certain.
However, "confirmation of facts" and "interpretation of causes" must be considered separately. Jumping to interpret this phenomenon through vaccine criticism or specific ideological frameworks is not scientifically justified; rather, it should be understood as the combined result of COVID-19 (especially the Delta variant), the drug crisis, healthcare collapse, and social disruption—this is the evaluation most faithful to current evidence.
Insurance company data is extremely valuable as a "warning bell," but the "interpretation of its causes" requires continued careful and evidence-based discussion.

The 2021 reports by some US life insurance companies indicating that working-age mortality rose to historic levels represent important indicators with several possible contributing factors. Such data is highly significant for life insurance companies as it directly impacts corporate profits. It can be evaluated from the following perspectives:
- Pandemic Impact: The COVID-19 pandemic beginning in 2020 likely played a major role in increased mortality rates. During this period, many countries experienced increases in infection-related deaths.
- Deterioration in Health Status: During and after the pandemic period, restrictions on healthcare access and mental stress may have caused other health problems to emerge or worsen.
- Data Reliability: Insurance companies face demands for accuracy in their published data, and are motivated to avoid financial losses, thus paying close attention to data reliability.
- Socioeconomic Factors: Economic uncertainty, unemployment rates, and changes in living conditions may also indirectly affect health and mortality rates.
Considering these points, such reports can become important indicators highlighting not only insurance industry interests but also broader social health problems. Therefore, these data require further investigation and careful analysis.

Regarding the report by some US life insurance companies that working-age mortality increased to historic levels in 2021, the evaluation should proceed as follows.
Life insurance companies are, by the nature of their business, extremely sensitive to mortality trends, and this report should be taken seriously.
- Reliability of Data Based on Profit and Loss: Life insurance companies set insurance premiums and pay death benefits based on policyholder mortality rates. If mortality rates rise, insurance death benefit payouts increase, directly and negatively affecting company revenue. Therefore, they constantly analyze the most accurate and up-to-date mortality data. Their reported "historic rise" in mortality rates indicates a situation so serious that it forces them to face massive increases in insurance payouts and requires review of business plans and underwriting standards.
- Professional Analysis: Life insurance companies employ experts called actuaries, who use vast amounts of data and sophisticated statistical models to precisely forecast mortality, morbidity, and life expectancy. Their analysis is based on advanced statistical models and long-term historical data. A statement of "historic rise" in a specific age group normally indicates a change that deviates far from ordinary fluctuations.
- Characteristics of Data Sources: Data reported by life insurance companies are limited to policyholders in their insurance portfolio. While this may not be fully representative of all working-age Americans, it still provides valuable information showing actual mortality trends in large and specific groups with particular health and economic conditions. Data from workers insured through group insurance via employers may particularly reflect health trends in specific industries or occupations.
- Potential Background (Considerations in Evaluation): Considering 2021 as the time period, the impact of the COVID-19 pandemic appears to be the primary factor. This includes not only death directly from the virus itself, but also indirect pandemic impacts such as strain on healthcare systems, delayed treatment of chronic diseases, changes in health behaviors, and increased mental health problems. Life insurance companies analyze how these factors affect insurance payouts and use this in future risk assessments.
In conclusion, the 2021 report by some US life insurance companies regarding working-age mortality rates should be evaluated as extremely credible, based on its direct impact on profit and loss and the nature of data-driven professional analysis. This suggests a serious public health crisis in a particular population segment and prompts consideration of further detailed analysis and response measures.
The report by US life insurance companies regarding the 2021 working-age mortality rate should be taken very seriously given the nature of the report.
Key Evaluation Points
- Reliability of Data Directly Affecting Profit and Loss: Life insurance companies calculate insurance premiums based on "expected mortality rates" and pay death benefits when policyholders die. If actual mortality rates exceed expectations, insurance payout amounts increase, directly negatively affecting company earnings (called "mortality gain and loss"). Therefore, life insurance companies collect and analyze mortality data with extreme rigor, and their reports are based purely on economic and statistical grounds, not emotion or ideology.
- Specifics of the "Historic Rise": Scott Davison, CEO of OneAmerica, reported that in Q3 and Q4 2021, the mortality rate for working-age people (ages 18-64) rose 40% compared to pre-pandemic baseline levels. He noted that this 40% figure far exceeds the 10% increase considered a "once-in-200-year catastrophe," representing an "unprecedented" level. Other life insurance companies are reported to have experienced similar trends. For example, Prudential experienced 95,000 deaths against expected 30,000 in Q3 2021, recording a $135 million loss in this business division.
- Background and Speculation on Causes (Insurance Company Perspective): Given the 2021 timeframe, the COVID-19 pandemic represents the primary suspected factor. However, insurance companies are focusing not only on COVID-19-related deaths but also on possible indirect pandemic impacts: insufficient healthcare access, delayed treatment of chronic diseases, and increased mental health problems. Davison from OneAmerica noted that COVID-19 deaths among working-age Americans may be underestimated, and that Long COVID and hospital capacity constraints limiting access to necessary healthcare may also lead to increased disability benefit claims.
- Professional Analysis by Actuaries: Life insurance companies employ actuaries using vast data and sophisticated statistical models to forecast mortality. The Society of Actuaries (SOA) data also shows that excess mortality was high across all age groups in 2021, with non-COVID deaths for ages 15-34 reported as 21.4% higher.
In conclusion,
Because life insurance companies are directly impacted by mortality rates in their business operations, they conduct rigorous data-driven analysis. The "historic rise" in working-age mortality reported by some life insurance companies in 2021 is based on concrete data directly affecting their profit and loss, not mere speculation or ideology. This represents a highly credible indicator suggesting serious public health challenges in specific populations and should be evaluated as extremely important information in assessing the broad impacts the pandemic has had on society.

The 2021 report by some US life insurance companies regarding increased working-age mortality (primarily ages 18-64) is highly credible as fact based on actual insurance claims data. Insurance companies must accurately grasp and reflect mortality fluctuations to maximize profit, making such reports based on profit and loss calculations rather than ideology.
Primary Reported Findings and Background
- OneAmerica (Indiana-based life insurance company): Working-age mortality in Q3 (July-September) 2021 increased 40% compared to the same period in 2019 (pre-pandemic). Similar trends observed industry-wide, with CEO stating "highest mortality rate in company history," pointing to Delta variant impact. Direct and indirect COVID-19 effects (underreported COVID deaths, hospital congestion limiting necessary care) identified as primary causes.
- Prudential, Unum, MetLife and others: Q3 2021 deaths exceeded expectations significantly (e.g., Prudential's 35-54 age group deaths tripled in proportional terms), with increased group life insurance claims reported. The Delta wave showed relatively stronger impact on young and working-age populations.
- Industry-wide and Actuarial Society (SOA) analysis: 2021 death benefit payments showed dramatic year-over-year increase. Working-age impact was proportionally larger than 2020, with total deaths exceeding 2020 levels (CDC data showing approximately 3.42 million in 2021 vs 3.39 million in 2020). The Delta variant impact was prominent in 2021, affecting unvaccinated and younger populations even during vaccine rollout.
These data align with CDC excess mortality statistics and SOA population/group life insurance analyses. Unlike 2020 centered on elderly populations, 2021 was characterized by relative increases in working-age groups.
Evaluation Points
- Why Reliability Is High: Insurance companies adjust reserves and premiums based on actual claims (death benefits) data. Over or underreporting directly impacts profit and loss; data is therefore objective. Multiple independent companies and actuarial analyses converge on the same trend, making this more than anecdotal evidence.
- Primary Causes: COVID-19 (particularly Delta variant) and pandemic-related indirect effects (delayed medical access, worsening of comorbidities). No evidence supports vaccine causation; Delta wave excess mortality represents the primary cause per insurance companies and CDC data. Fact-checkers have debunked "vaccines as cause" claims.
- Contextual Importance: The US experienced excess mortality throughout 2020-2022. The 2021 shift toward working-age populations was notable, with particularly strong impact on group life insurance (employer-provided). Long-term perspective suggests such data may lead to insurance rate adjustments and revised underwriting standards.
Important Caveats
Insurance company reports show "what happened" but detailed "why" causation (e.g., specific policies or factors) requires separate CDC and epidemiological research verification. The 2021 increase should be positioned as a temporary pandemic phenomenon, with subsequent trends requiring separate examination. Overall, this report reflects data-driven reality and should avoid both underestimation and overinterpretation. If additional recent data is needed, consult official CDC and SOA reports.
