MIT<\/a> Mobility-related data show the pandemic has had a lasting effect, limiting the breadth of places people visit in cities. <\/p>\n\n\n\n

The Covid-19 pandemic has reduced how often urban residents intersect with people from different income brackets, according to a new study led by MIT researchers.<\/p>\n\n\n\n

Examining the movement of people in four U.S. cities before and after the onset of the pandemic, the study found a 15 to 30 percent decrease in the number of visits residents were making to areas that are socioeconomically different than their own. In turn, this has reduced people\u2019s opportunities to interact with others from varied social and economic spheres.<\/p>\n\n\n\n

\u201cIncome diversity of urban encounters decreased during the pandemic, and not just in the lockdown stages,\u201d says Takahiro Yabe, a postdoc at the Media Lab and co-author of a newly published paper detailing the study\u2019s results. \u201cIt decreased in the long term as well, after mobility patterns recovered.\u201d<\/p>\n\n\n\n

Indeed, the study found a large immediate dropoff in urban movement in the spring of 2020, when new policies temporarily shuttered many types of institutions and businesses in the U.S. and much of the world due to the emergence of the deadly Covid-19 virus. But even after such restrictions were lifted and the overall amount of urban movement approached prepandemic levels, movement patterns within cities have narrowed; people now visit fewer places.<\/p>\n\n\n\n

\u201cWe see that changes like working from home, less exploration, more online shopping, all these behaviors add up,\u201d says Esteban Moro, a research scientist at MIT\u2019s Sociotechnical Systems Research Center (SSRC) and another of the paper\u2019s co-authors. \u201cWorking from home is amazing and shopping online is great, but we are not seeing each other at the rates we were before.\u201d<\/p>\n\n\n\n

The paper, \u201cBehavioral changes during the Covid-19 pandemic decreased income diversity of urban encounters<\/a>,\u201d appears in Nature Communications<\/em>.

A decline in exploration<\/strong><\/p>\n\n\n\n

To conduct the study, the researchers examined anonymized cellphone data from 1 million users over a three-year period, starting in early 2019, with data focused on four U.S. cities: Boston, Dallas, Los Angeles, and Seattle. The researchers recorded visits to 433,000 specific \u201cpoint of interest\u201d locations in those cities, corroborated in part with records from Infogroup\u2019s U.S. Business Database, an annual census of company information.  <\/p>\n\n\n\n

The researchers used U.S. Census Bureau data to categorize the socioeconomic status of the people in the study, placing everyone into one of four income quartiles, based on the average income of the census block (a small area) in which they live. The scholars made the same income-level assessment for every census block in the four cities, then recorded instances in which someone spent from 10 minutes to four hours in a census block other than their own, to see how often people visited areas in different income quartiles. <\/p>\n\n\n\n

Ultimately, the researchers found that by late 2021, the amount of urban movement overall was returning to prepandemic levels, but the scope of places residents were visiting had become more restricted.<\/p>\n\n\n\n

Among other things, people made many fewer visits to museums, leisure venues, transport sites, and coffee shops. Visits to grocery stores remained fairly constant \u2014 but people tend not to leave their socioeconomic circles for grocery shopping.<\/p>\n\n\n\n

\u201cEarly in the pandemic, people reduced their mobility radius significantly,\u201d Yabe says. \u201cBy late 2021, that decrease flattened out, and the average dwell time people spent at places other than work and home recovered to prepandemic levels. What\u2019s different is that exploration substantially decreased, around 5 to 10 percent. We also see less visitation to fun places.\u201d He adds: \u201cMuseums are the most diverse places you can find, parks \u2014 they took the biggest hit during the pandemic. Places that are [more] segregated, like grocery stores, did not.\u201d<\/p>\n\n\n\n

Overall, Moro notes, \u201cWhen we explore less, we go to places that are less diverse.\u201d<\/p>\n\n\n\n

Different cities, same pattern<\/strong><\/p>\n\n\n\n

Because the study encompassed four cities with different types of policies about reopening public sites and businesses during the pandemic, the researchers could also evaluate what impact public health policies had on urban movement. But even in these different settings, the same phenomenon emerged, with a narrower range of mobility occurring by late 2021.<\/p>\n\n\n\n

\u201cDespite the substantial differences in how cities dealt with Covid-19, the decrease in diversity and the behavioral changes were surprisingly similar across the four cities,\u201d Yabe observes.<\/p>\n\n\n\n

The researchers emphasize that these changes in urban movement can have long-term societal effects. Prior research has shown a significant association between a diversity of social connections and greater economic success for people in lower-income groups. And while some interactions between people in different income quartiles might be brief and transactional, the evidence suggests that, on aggregate, other more substantial connections have also been reduced. Additionally, the scholars note, the narrowing of experience can also weaken civic ties and valuable political connections.<\/p>\n\n\n\n

\u201cIt\u2019s creating an urban fabric that is actually more brittle, in the sense that we are less exposed to other people,\u201d Moro says. \u201cWe don\u2019t get to know other people in the city, and that is very important for policies and public opinion. We need to convince people that new policies and laws would be fair. And the only way to do that is to know other people\u2019s needs. If we don\u2019t see them around the city, that will be impossible.\u201d<\/p>\n\n\n\n

At the same time, Yabe adds, \u201cI think there is a lot we can do from a policy standpoint to bring people back to places that used to be a lot more diverse.\u201d The researchers are currently developing further studies related to cultural and public institutions, as well and transportation issues, to try to evaluate urban connectivity in additional detail.<\/p>\n\n\n\n

\u201cThe quantity of our mobility has recovered,\u201d Yabe says. \u201cThe quality has really changed, and we\u2019re more segregated as a result.\u201d<\/p>\n XrQ EdHxBgfpuc PGnGwSD<\/a><\/div><\/div>","protected":false},"excerpt":{"rendered":"
