Beijing Is Intentionally Underreporting China’s Covid Death Rate (Part 1)

  • “The official figures do not reflect the true death toll, particularly in China…” – Newsweek

WUHAN, CHINA – JANUARY 22: (CHINA OUT) A man wears a mask while walking in the street on January … [+] 22, 2020 in Wuhan, Hubei province, China. A new infectious coronavirus known as \2019-nCoV\ was discovered in Wuhan as the number of cases rose to over 400 in mainland China. Health officials stepped up efforts to contain the spread of the pneumonia-like disease which medicals experts confirmed can be passed from human to human. The death toll has reached 17 people as the Wuhan government issued regulations today that residents must wear masks in public places. Cases have been reported in other countries including the United States, Thailand, Japan, Taiwan, and South Korea. (Photo by Getty Images)

In the United States, more than 825,000 people have died from Covid.

China’s official Covid death count is… 4,636.

(Pause right there, to consider that purported Fact.)

The difference in mortality rates is even more shocking. The Chinese government reports a Covid death rate overall of 0.321 per 100,000 population. The U.S. Covid death rate is 248 per 100,000 population –  800 times higher. 

Really? Much of the Western media has accepted these figures as valid, and pundits have pondered the gross failure (as it would seem) of American policies. Meanwhile, the Chinese authorities are triumphalist. As they see it, their success of their “zero covid” approach — marked by severe lockdowns for entire cities, travel bans, intensive contact tracing, military enforcement – simply demonstrates the superiority of their system.

The number of cases of coronavirus rose to 1,975 in mainland China on Sunday. Authorities tightened restrictions on travel and tourism this weekend after putting Wuhan, the capital of Hubei province, under quarantine on Thursday. The spread of the virus corresponds with the first days of the Spring Festival, which is one of the biggest domestic travel weeks of the year in China. Popular tourism landmarks in Beijing including the Forbidden City, Badaling Great Wall, and The Palace Museum were closed to the public starting Saturday. The Beijing Municipal Education Commission announced it will delay reopening schools from kindergarten to university. The death toll on Sunday rose to 56.

  • “The Communist Party is rebranding itself as the unequivocal leader in the global fight against the virus. The state-run news media has hailed China’s response to the outbreak as a model for the world, accusing countries like the United States and South Korea of acting sluggishly to contain the spread. ‘Some countries slow to respond to virus,’ read a recent headline from Global Times, a stridently nationalistic tabloid controlled by the Chinese government. Online influencers have trumpeted China’s use of Mao-style social controls to achieve containment, using the hash tag, ‘The Chinese method is the only method that has proved successful.’” – The New York Times

But can we believe the Chinese numbers?

Origins vs Outcomes

Over the past two years, our understanding of the Covid phenomenon has evolved. Most of the critical attention has focused on determining the origin of the virus. The initial default hypothesis – that Covid is zoonotic or animal-transmitted – has come under scrutiny. The lab-leak theory has gained support. This is of course highly contentious, and any reassessment has been vigorously resisted by the Chinese. The origin question is scientifically complex, touching on the taxonomy and ecology of Asian bat populations, the typical patterns of viral evolution, and the minute details of genomic sequences. That debate will continue, and some are saying it may never be fully resolved. And in a sense, it is academic. Covid is here now and we have to deal with it regardless of how it originated.

But – the second and much more obvious discrepancy in the Covid narrative focuses on a question that is arguably more important: What is the best way to contain the spread of the virus? How can we reduce the levels of infection, hospitalization and death? 

To answer this question, the Covid mortality rate is a key metric. It defines the primary desired outcome of public health policy, and the primary measure of success or failure. If the mortality figures are unreliable, or subject to manipulation, we are in trouble. 

And we are in trouble. Because the mortality rates presented for China are plainly implausible. The Chinese death rates are much higher than what is published.

This is now becoming clear, as new statistical approaches start to shed light on the gap between the reported Covid death rates and the true death rates – the so-called “excess mortality” – comparing current Covid-impacted levels of mortality in careful ways with past averages and trends, to reveal the “surplus deaths” beyond the normal baseline, most of which can be attributed to undiagnosed, misdiagnosed or unreported Covid. This sort of close analysis of Covid mortality figures is being pursued by researchers at institutions including Johns Hopkins University in the U.S, Cambridge University in the UK, the Max Planck Institute in Germany, and by several leading media companies, including as the New York Times, Reuters, the Financial Times, and The Economist

This effort has started to reveal the truth – and the truth is shocking. 

The Big Discrepancy 

Covid death statistics are vastly understated, almost everywhere

  • “[The true death toll] is two or three times higher than the number of deaths we know about.” – Amber D’Souza, Prof. of Epidemiology at Johns Hopkins Bloomberg School of Public Heath
  • “Whatever number is reported is going to be a gross underestimate.” – Tim Riffe, a demographer at the Max Planck Institute for Demographic Research in Germany.”

The discrepancy varies from country to country. 

  • “The official death toll is a false figure… [and] it’s much worse than that. There’s no doubt that some countries are under-reporting COVID-19 deaths.” – David Spiegelhalter, a statistician at the University of Cambridge

The U.S. is apparently “guilty” of underreporting. According to the New York Times study, we probably undercount the prevalence of Covid deaths by about 17%. The Economist found a 7% discrepancy. They later increased their estimate of U.S. under-reporting to 30%. 

China is another story. Its official statistics understate the Chinese Covid death rate by 17,000% (according to The Economist’s model). 

In fact, based on excess mortality calculations, The Economist estimates that the true number of Covid deaths in China is not 4,636 – but something like 1.7 million. 

That is, China’s cumulative death toll is likely at least double that of the United States. 

In the case of the United States, the discrepancy is inadvertent. It can be explained in terms of inefficiencies and frictions in the system that cause some data loss. 

In the case of China, it is clearly intentional. The Covid death figures are being grossly — one might say, crudely – manipulated by the Chinese authorities.

The Chronic Unreliability of Chinese Official Figures 

In some respects, this was to be expected, based on what we know of Beijing’s tendencies to tamper with the data in other areas. E.g.,  

  • The unreliability of official Chinese economic data is notorious; no need here for a lengthy demonstration. A detailed study by the St Louis Federal Reserve Bank concluded that “skepticism for Chinese official economic data is widespread, and it should be.” (A subject or another column.)
  • The pattern of non-cooperation, denial, obstruction, cover-up and data-destruction by Chinese authorities with respect to any inquiry involving Covid is now well-documented. [For details, see the recent book Viral: The Search for the Origin of COVID-19, by Matt Ridley and Alina Chan, published in November 2021 by Harper Collins.]

The Missing Covid Data

More specific to the Covid mortality question are the extraordinary lacunae in Chinese data related to Covid cases. 

It is becoming clear that the suppression or deletion of data related to excess deaths in China began shortly after the pandemic started. As a result, most multi-country studies of Covid prevalence and outcomes are forced to omit China from their analyses. 

  • November 2020: An academic study of 22 countries – “There are no data from China.”
  • January 2021: An academic study covering 77 countries – “[For China] the email addresses did not work and returned an error message… ‘We are sorry to inform you that we do not have the data you requested.’ … We treat Taiwan and Hong Kong as separate countries. They release monthly mortality data, whereas China does not.”
  • February 2021: One of the first mainstream media presentations of the excess mortality methodology by the New York Times catalogued the underreporting of nearly half a million Covid deaths in 35 countries – but did not include China. 
  • May 2021: The Economist – “The official death counts capture just a small share of the disease’s true impact… China’s data on excess deaths are heavily delayed or entirely unavailable.” 
  • In July 2021: A Journal of American Medical Association study covering 67 countries still had nothing on China.
  • August 2021: “Data for China was unavailable.” – The Financial Times
  • September 2021: A University of Washington survey, translated into the map reproduced here — shows that even 20 months into the pandemic China was not publishing data on excess mortality (half the country reported nothing at all, and the other half reported de minimis); China was the only country in the world at this point, other than Greenland and the former Spanish Sahara, that did not provide this data. 

China\’s Data Gap

Chart by author

China’s suppression of data related to the origins of the virus – e.g., the lab records of the Wuhan Institute of Virology, or the whitewashing of the WHO inquiry – is well known. The ongoing suppression of basic mortality data – which continues now two years into the pandemic – has received much less attention. It is just as serious an impediment to the scientific understanding of disease and the effectiveness of countermeasures. 

The Case of the Missing Wuhan Data

The missing data problem also emerges from an examination of the the hotspot — the only hotspot for Covid in all of China — Wuhan, in Hubei province. According to China’s official statistics, Hubei has accounted for 97% of all Covid-related deaths in the country. (The outbreak in Xian in the last few weeks may soon alter this calculation.) 

All of the reported deaths in Wuhan/Hubei occurred between Jan 1 and March 31 of 2020. After that, all reporting ceased. 

  • “There are no excess-death statistics for the period from April 2020 onwards.” 

Even the data that “escaped” in this brief window show a puzzling degree of instability. The extreme geographical and temporal concentration of the disease outbreak, affecting just a single major urban center, during a short period, under almost total lockdown, ought to have simplified the task of data collection (compared to the difficulties of collating reports from hundreds or thousands of reporting sites spread across an entire country). 

However, the Wuhan/Hubei death count has been subject to a series of revisions, adjustments, and gaps. 

After the Wuhan outbreak was allegedly brought under control by the end of March 2020, the original “final count” of Covid deaths in the city was set at 2,579. Then in April, an adjustment added another 1,290 deaths, said to be “the result of patients who died at home without a diagnosis in the early stages of the outbreak and failures by hospitals to report numbers correctly.” That brought the Wuhan count up to 3,869, where it sits today. Another 643 deaths came from the province of Hubei outside of the city, for a total of 4,512. (Beyond of Hubei, there have been just 124 Covid deaths reported in all of China over two years.)

In February 2021, an article in the British Medical Journal analyzed the overall mortality statistics from Wuhan. The researchers found that there were 5,954 more deaths in Wuhan compared to the same period in 2019 – “as a result of an eightfold increase in deaths from pneumonia, mainly covid-19 related.” This “excess mortality” calculation suggested that the actual Covid death count for that period was at least 54% higher than the official figure.  

In May 2021, The Economist was able to review and reanalyze some of the data used by the BMJ researchers. Using more sophisticated methods to estimate excess mortality, the Economist’s team found that

  • The data suggest that total excess deaths in Wuhan between January 1st 2020 and March 31st 2020 numbered 13,400. That is more than triple the official count, and more than double the estimate in the BMJ paper. 

To summarize: 

Wuhan Anomaly

Another aspect of the Wuhan data also indicates underreporting. The total case fatality rate in Wuhan– the percentage of infected individuals who died, based on the official numbers – for this period was 5.6%. This is 4 times higher than the fatality rate of about 1.5% for Covid infections in the United States. 

Covid Case Fatality Rates

There are two possible explanations. Either Covid was far more deadly in early 2020 in Wuhan than anywhere else, at any other time. Or – the numerator in the CFR calculation, which is the number of infections officially reported, was too small by a factor of 3 or 4.

Pause again to consider this single-city, micro-perspective. Several points stand out:

  • It seems that the official statistics for Wuhan failed to report about three quarters of the Covid infections, and three quarters of the actual Covid deaths. 
  • The Wuhan mortality rate calculated by The Economist was 121 per 100,000 population for Q1 2020. As authors comment, “[Compared to London and New York] if we were to adjust [Wuhan’s figures] for demography and density in those cities, the first wave might look tragically similar.” (Note: Wuhan was under a military-grade lockdown for most of this time period – far more stringent than the measures imposed in Western cities. This should have suppressed the rates of infection and death.) 
  • In any case, the Wuhan Covid mortality rate for just this limited 90-day period is 376 times higher than the currently cited official death rate for the country as a whole.

The Travel “Surge”

In 2 years since Covid emerged, there have been just 2-300 deaths from the disease among the 1.3 billion Chinese who do not live in Hubei province – a mortality rate of .002 per 100,000 population – 124,000 times lower than the mortality rate in the U.S. 

This suggests that the measures taken by the government in the first 90 days of the pandemic were so successful that Covid has effectively disappeared entirely from China. 

How credible is it that the deaths from Covid – after spiking to levels 4 times higher than anywhere else – suddenly stopped on April 1? And how credible is it that the virus never escaped from the Wuhan/Hubei hotspot to rage through the rest of China? 

The isolation of the disease to Wuhan that this implies is also implausible. A study of the travel patterns in from Wuhan in January 2020, published in Nature magazine describes “an outbound travel surge from Wuhan before travel restrictions were implemented.” 

The first case of Covid in Wuhan was diagnosed (officially) on Dec 31, 2019. The travel ban was not imposed until January 23, 2020, 2 days before the Lunar New Year (LNY). The 40-day period (called Chunyun) associated with the LNY period ran from January 10 to February 18. Chunyun means travel for the Chinese, on an enormous scale. 

  • “In terms of raw numbers in almost every category, the Chinese New Year Spring Festival is the largest human event on the planet. In the seven days of the Lunar New Year, Chinese buy railway tickets online at a rate of more than 1,000 per second. Millions of Chinese people go home for the Chinese New Year Spring Festival during “chunyun” — the annual spring migration.”

In 2019, there were nearly 3 billion individual journeys made in connection with Chunyun. In 2020, Wuhan experienced its “surge” during the critical period for the propagation of Covid – the three weeks after the contagion had established itself and before the travel ban. 

  • “Outbound travel volume from Wuhan was marked by an early-January peak, followed by a sharper second peak in the days before the LNY holiday [Jan 25]… The early-January peak in Wuhan coincided with the beginning of winter break for university students in China, approximately one million of whom study in Wuhan… The second peak was higher in 2020 than 2019.” 

It is not credible that the infection was stopped dead in its tracks, completely contained by April 1, 2020, and its impact (in terms of mortality) essentially limited to Wuhan/Hubei. 

Part 2: Shedding Light on the Missing Data

This column has focused on the gaps in the data provided by China. It seems clear that sometime around April 2020, Beijing decided to stop reporting most Covid-related statistics.

The destruction, alteration or suppression of this vital data is a problem not just for China, and its citizens, but for the whole world. It distorts our understanding of Covid and how best to respond to it. It feeds geopolitical anxieties. It entails serious economic consequences which are only now beginning to become apparent.

The 800-to-1 ratio of US-to Chinese mortality rates is a statistical, medical, biological, political and economic impossibility.

In Part 2, we will examine the available statistics more closely to illuminate this impossibility. And in Part 3, we will try to assess the economic impact of all this.
