 Failure to reduce jail population is the Achilles heel for the efforts to mitigate the spread of COVID-19 in the U.S.


MARICOPA COUNTY — COVID-19 could claim the lives of approximately 69% more people in Maricopa County than current projections stipulate if jail populations are not dramatically and immediately reduced, according to a new epidemiological model released today by the ACLU and academic research partners. The total U.S. death toll could be 100,000 higher than current predictions due to failures to reduce jail populations.

The findings indicate that — even if communities across the United States continue practicing social distancing and following public health guidance — they will still experience much higher death rates if no substantial action is taken to reduce jail populations.

The projected deaths in Maricopa County not accounting for jails lands at 1,384 deaths. However, once accounting for jails, projected deaths in jails lands at 358 deaths and additional deaths in the community lands at 1,984 deaths for a total increase of 958 deaths in Maricopa County.

“Getting people out of dangerous conditions in jails and prisons is the only way to ensure lives are saved,” said ACLU of Arizona Executive Director Alessandra Navidad. “In our state, we know that far too many people are incarcerated for unnecessarily long sentences. There’s been an urgent, bipartisan call to reduce the jail and prison populations, but this pandemic is pushing us past the breaking point because the longer we wait to release people, the greater the loss of life.”

Arizona has the fifth highest incarceration rate in the nation. The U.S. is the largest incarcerator in the world, with just four percent of the world’s population and 21 percent of its incarcerated population. About 40 percent of all incarcerated people suffer from at least one chronic health condition, such as asthma or diabetes. This means the U.S. faces a unique challenge in mitigating the spread of COVID-19 and is likely facing a much higher death count than models based on data from other countries predict.

The ACLU model used data pulled from more than 1,200 midsize and large jail systems around the country, whose surrounding communities account for 90 percent of the U.S. population. It found that, unequivocally, keeping people out of jail saves lives — both inside the jail and in the surrounding community. Other key findings from the model include:

  • If a model that doesn’t account for jails predicts the U.S. death toll will be 100,000, our model shows that that projection undercounts deaths by 98 percent. Actual deaths, once we account for jails, could be more than double, rising to 200,000.
  • Implementing swift, bold reforms to reduce arrests by 50 percent can save 12,000 lives in jails, and 47,000 lives in the surrounding communities.
  • Aggressive action and policy change could save as many as 23,000 people in jail and 76,000 in the broader community if we stop arrests for anything but the five percent of crimes defined as most serious by the FBI — including murder, rape, and aggravated assault — and double the rate of release for those already detained.
  • States that have begun to reduce their jail populations are quantifiably saving lives. Colorado, for example, has so far achieved a 31 percent reduction in jail population. Our model found this likely will save 1,100 lives — reducing total lives lost in the state by 25 percent.
  • Every day that goes by without action means more people will die. Delaying action for a week could mean a difference of 18,000 lives lost in the U.S.

“The prevailing epidemiological models largely fail to take into account our incarceration rates and the complete absence of social distancing in our jails — which is why we had to build our own model,” said Lucia Tian, chief analytics officer, ACLU. “While we always knew that jails would have an impact on loss of life in this pandemic, the model shows us just how large that impact may be — that even under our best case scenarios, we could be looking at 100,000 more deaths. We can't save our community while ignoring our jails.”

The original model was developed by Dr. Nina Fefferman at the University of Tennessee, Dr. Eric Lofgren at Washington State University, and Dr. Kristian Lum from the University of Pennsylvania, in collaboration with Aaron Horowitz and Brooke Madubuonwu of the ACLU’s data analytics team, experts from the ACLU and other corrections organizations contributed expertise.

The ACLU of Arizona is continuing to call on Gov. Ducey to issue an executive order to release from prison who are elderly, people with underlying health conditions, and people with just a short time left on their sentence. It is also calling on Maricopa County Attorney Allister Adel to proactively push for the broad release of people being held pre-trial in county jails.
