Black people are more than four times more likely to die from Covid-19 than white people, according to stark official figures exposing a dramatic divergence in the impact of the coronavirus pandemic in England and Wales.
The Office of National Statistics found that the difference in the viruss impact was caused not only by pre-existing differences in communities wealth, health, education and living arrangements.
It discovered that after taking into account age, measures of self-reported health and disability and other socio-demographic characteristics, black people were still almost twice as likely as white people to die a Covid-19-related death.
Bangladeshi and Pakistani males were 1.8 times more likely to die from Covid-19 than white males, after other pre-existing factors had been accounted for, and females from those ethnic groups were 1.6 times more likely to die from the virus than their white counterparts.
The risk of Covid-19 death for people from Chinese and mixed ethnic groups was found to be similar to that for white people.
“These results show that the difference between ethnic groups in Covid-19 mortality is partly a result of socio-economic disadvantage and other circumstances, but a remaining part of the difference has not yet been explained,” the ONS said.
Guardian research last month confirmed suspicions that minority groups faced the greatest risk from the coronavirus and showed that areas with high ethnic minority populations in England and Wales tended to have higher mortality rates in the pandemic.
Zubaida Haque, the deputy director of the Runnymede Trust, a race equality thinktank, described the findings as alarming. “We cannot ignore how important racial discrimination and racial inequalities, for example, in housing, are, even among poorer socio-economic groups,” she said. “These factors are important but are not taken into account in most statistical modelling of Covid-19 risk factors.”
While only 2% of white British households experienced overcrowding from 2014 to 2017, 30% of Bangladeshi households, 16% of Pakistani households and 12% of black households experienced this, according to a study of the English Housing Survey.
These groups are more likely to work in frontline roles in the NHS in England: nearly 21% of staff are from ethnic minorities, compared with about 14% of the population of England and Wales. Black, Bangladeshi and Pakistani populations have been shown to face higher levels of unemployment and child poverty than white groups.
Helen Barnard, the acting director of the Joseph Rowntree Foundation, said the findings were “a stark reminder that although we are all weathering the same storm, we are not all in the same boat”.
“With the Bank of England now forecasting the deepest recession on record, we must ask ourselves what kind of society we want to live in after the virus passes,” Barnard said. “It doesnt have to be like this. As a society that prides itself on justice and compassion, we can and must do better.”
The figures, covering deaths from 2 March to 10 April, are the first official snapshot of the way Covid-19 has affected different ethnic groups in England and Wales. There has been widespread concern that pre-existing health inequalities between black and minority ethnic populations – particularly in relation to cardiovascular disease and diabetes – are being amplified during the pandemic.
To try to understand how much of the difference in Covid-19 morbidity was to do purely with ethnicity, the statisticians adjusted for age as well as region, rural and urban classification, area deprivation, household composition, socio-economic position, highest qualification held, household tenure, and health or disability as recorded in the 2011 census.
“The fully adjusted results show differences in risk between ethnic groups that are specific to those ethnic groups and are not caused by any of the factors listed on which members of the groups might differ,” the ONS concluded.
After all these factors were accounted for, Indian men and women were less likely than people from Bangladeshi and Pakistani background to die from Covid-19, but were still 1.3 times and 1.4 times more vulnerable than white people.
Chinese women were the only group to be less vulnerable than white people, after adjusting for other differences, while Chinese men were 1.2 times more likely to die from the disease than white people.
The ONS also checked to see if, within ethnic groups, socio-economic class made a difference. They found that the differences in risk of Covid-19-related death across ethnic groups were of similar magnitudes within all three socio-economic classes.
The differences in the risk of dying from Covid-19 could be driven by factors not included in its model, the ONS acknowledged.
Some groups may be over-represented in public-facing occupations and could be more likely to be infected by Covid-19 . About 12.8% of workers from Bangladeshi and Pakistani backgrounds work in public-facing transport jobs such as bus, coach and taxi driving, compared with 3.5% of white people. The ONS said it plans to conduct further work to identify occupations that are particularly at risk.
A study released on Thursday analysing the NHS health records of 17.4 million UK adults gave further insights into the possible causes of the increased risk for people from BAME backgrounds. Like the ONS data, the study found that people of black and Asian backgrounds were at higher risk of death, and it ruled out the idea that this was largely due to higher rates of underlying medical problems in these groups.
“People have very reasonably speculated that the increased risk among BME people might be due to people having higher risk of cardiovascular disease or diabetes,” said Ben Goldacre, the director of the DataLab in the Nuffield Department of Primary Care Health Sciences at the University of Oxford, who co-led on the study. “Our analysis shows that is actually not the case. That is not the explanation. Weve been able to exclude one of the current preferred explanations for why BME people face higher risk.”
The authors called for further research on the contribution of occupational risk and whether people from BAME backgrounds were placed at increased risk of exposure and infection. The study, which has not yet been peer-reviewed, found that people from deprived social backgrounds were also at a higher risk, and again this finding could not be explained by other risk factors.
Meanwhile, Wasim Hanif, a professor of diabetes and endocrinology at University Hospital Birmingham, said the ONS data was not robust enough to give the full reasons for the difference in the likelihood of dying from Covid-19.
The research accounts for health problems reported by people who filled in the 2011 census, but Hanif said differences in the extent of other underlying diseases in different ethnic groups in Britain – so-called co-morbidities – which have not been accounted for by the ONS, may be significant.
For example, in the UK people of Pakistani and Bangladeshi descent are three to four times more likely to get diabetes earlier in life than white people, and the ratio is between two and three for black and Indian-origin people, he said.
However deprivation, which is a strong predictor for ill-health, was factored into the ONS analysis, so it remains unclear how much the inclusion of co-morbidities would change the results.
The Department of Health and Social Care said: “This virus has sadly appeared to have a disproportionate effect on people from BAME backgrounds. It is critical we find out which groups are most at risk so we can take the right steps to protect them and minimise their risk.
“We have commissioned Public Health England to better understand the different factors, such as ethnicity, obesity and geographical location that may influence the effects of the virus.”
