A key measure of COVID-19’s unfold within the U.S. has been decidedly bizarre for greater than every week. Day after day, the states with the highest infection rates—new instances per 100,000 residents—have been North Dakota, South Dakota, and Montana, among the many least densely populated states in America. With social distancing crucial to preventing COVID-19, how can this be? The rising reply is critical for people, employers, and policymakers.
Again in April, when New York Metropolis was the pandemic’s epicenter, all of it made sense. The town has 27,012 folks per sq. mile, the very best density of any main U.S. metropolis. In fact, it will be the nation’s hottest scorching spot. However North Dakota and South Dakota have 4 folks per sq. mile. Montana has seven. As of in the present day, North Dakota’s an infection charge is 78 instances higher than New York Metropolis’s.
It’s instantly apparent that density just isn’t the enemy, as weird as that appears. Researchers from the Johns Hopkins Bloomberg College of Public Well being and the College of Utah uncovered this shock in a paper printed in June. They discovered no statistically important relationship between density and COVID-19 an infection charges, including, “this runs counter to our preliminary expectations.” But when density isn’t the enemy, then what’s?
The researchers urged a number of components that might account for the counterintuitive outcome, and more moderen research reinforce their speculation. The lead creator of the paper, the Bloomberg College’s Shima Hamidi, tells Fortune: “Residents of dense locations are higher geared up to remain at residence, scale back their journeys, and adjust to public well being advisories akin to stay-at-home orders due to their higher entry to companies akin to residence supply.” As well as, these folks are usually extra conscious of the menace, so that they “usually tend to voluntarily adhere to social distancing advisories akin to avoiding crowded locations (eating places, bars, seashores, and many others.) in comparison with their counterparts in low density areas.”
Extra broadly, says David J. Peters, an affiliate professor of rural sociology at Iowa State College, “rural America is extra weak to COVID-19 than cities are.” That’s as a result of “rural areas are inclined to have older populations than the nationwide common, with extra power well being circumstances that increase the chance of growing extra extreme instances of COVID-19,” he writes. “In addition they are usually residence to massive group services, akin to prisons, meatpacking crops, and nursing properties, the place the virus can shortly unfold to residents, and workers can carry it again into the group.” In contrast, “cities have decrease percentages of older residents and other people dwelling in institutional settings.”
Attitudes may additionally play a job, although they weren’t studied within the analysis. Earlier than South Dakota governor Kristi Noem hosted President Trump at an Independence Day celebration at Mount Rushmore, she told Fox news, “we gained’t be social distancing.” Masks have been accessible, however few within the tightly packed crowd of greater than 7,000 wore them. The state additionally declined to cancel the annual August bike rally in Sturgis, in opposition to the desires of some locals. About 250,000 attended. Neither of the Dakotas has a statewide mask mandate.
The notion that density just isn’t the enemy runs counter to probably the most extensively held typical knowledge on the pandemic. Surging costs of suburban and exurban properties mirror the view that density is dangerous—that “our closeness makes us weak,” as New York governor Andrew Cuomo said in March. Pre-pandemic, city planners nationwide centered on growing density as a approach to fight sprawl, however public opinion turned abruptly in opposition to that pattern. Hamidi and her coauthors consider that’s a mistake. “Our findings counsel that planners ought to proceed to observe and advocate for compact locations relatively than sprawling ones,” they conclude, “as a consequence of a number of environmental, transportation, well being, and financial advantages of compact improvement.”
It’s nonetheless early for all large-scale pandemic-related analysis; future work will change our understanding additional. However these towering an infection charges in America’s large open areas are telling us loudly that a few of our earlier considering was off-base. As residence costs plunge in Manhattan, simply possibly it’s time to purchase.
