Writing in the journal PNAS, researchers from several California universities describe how they used anonymized cell phone location data and census info to show a dramatic reversal in how mobile Americans have been this year. Before Covid-19 struck, rich Americans moved about more than poor Americans—they can always afford to travel. But between January and April, that flipped. Rich folk are now far more likely to stay completely at home than poor folk: The study found that 25 percent more high earners stayed completely at home during the pandemic, compared to the number of them who had stayed home before. That increase was only 10 percent among low earners. And that has major implications for how we as a nation can fight the pandemic.
“In the early stages of the Covid-19 pandemic, there was a clear mobility response across the board,” says University of California, Davis environmental economist Joakim Weill, lead author on the paper. “In the US, everyone started to stay at home more. But we also found that there is a clear differential between wealthier communities and poor communities, where individuals in wealthier neighborhoods tended to stay at home much more than people in poorer neighborhoods.”…
Close to half of the wealthiest Americans stayed completely at home on weekdays in April, compared to less than 40 percent of low-earners. The poor traveled farther distances on average: In the same month, people who live in lower-income areas traveled between 5 and 6 kilometers, while the rich traveled closer to 4. The rich nearly halved their visits to recreational and retail areas in April, while the poor cut their visits by only a quarter—perhaps because their jobs required them to return to work there.
To be clear, the researchers can’t definitively say why the data shows this dramatic discrepancy, but they can begin to speculate. For one, essential workers often earn lower incomes, like clerks at grocery stores and pharmacies. Indeed, the US Bureau of Labor Statistics has found that among Americans 25 and older with less than a high school diploma, just 5 percent teleworked in June. On the other hand, 54 percent of Americans with a bachelor’s or more advanced degree were able to work remotely.
Social class is connected to mobility, health, and a whole lot of factors in social life. The anonymized cell phone data also seems to align with other patterns: those who can leaving certain big cities as well as differences in COVID-19 cases across communities and racial and ethnic groups.
As the article goes on to note, the fact that anyone can contract COVID-19 is not the same as saying everyone has the same likelihood of contracting COVID-19. Those with resources have more options in how to respond to crises plus more options when it comes to treatment. These differences are generally present regarding health but a large pandemic reveals some of the underlying patterns that deserve attention.
