COVID-19 Disproportionately Affects the Poor

COVID-19 infection rates are notably higher in communities with high poverty rates than in more affluent areas, according to an analysis of ZIP code and city data for California’s 12 most populous counties.

COVID-19 Infection Rates

Over the course of the pandemic, COVID-19 infections have battered high-poverty neighborhoods in California on a staggeringly different scale than more affluent areas, a trend that underscores the heightened risks for low-wage workers as the state endures a deadly late-autumn surge.

A California Healthline review of local data from the state’s 12 most populous counties found that communities with relatively high poverty rates are experiencing confirmed COVID-19 infection rates two to three times as high as rates in wealthier areas. By late November, the analysis found, about 49 of every 1,000 residents in the state’s poorest urban areas — defined as communities with poverty rates higher than 30% — had tested positive for COVID-19. By comparison, about 16 of every 1,000 residents in comparatively affluent urban areas —communities with poverty rates lower than 10% — had tested positive.

Epidemiologists say the findings offer evidence of the outsize risk being shouldered by the millions of low-wage workers who live in those communities and do the jobs state and federal officials have deemed essential in the pandemic. These are the grocery store clerks, gas station cashiers, home health aides, warehouse packers, meat processors, hospital janitors and myriad other retail and service employees whose jobs keep the rest of us comfortable, clothed and fed. Those jobs cannot be done remotely.

“People are being forced to go to work, possibly not able to protect themselves adequately,” said Dr. Christian Ramers, an infectious disease specialist at Family Health Centers of San Diego. “If you are living paycheck to paycheck, it’s a very hard decision for some people, if they feel OK, to not go to work or to even quarantine if they know that they were exposed, because they need to pay rent and they need to pay the bills.”

To examine income and COVID infection rates, California Healthline obtained data showing the number of cases for each ZIP code in nine of the state’s 12 most populous counties: AlamedaFresnoKernOrangeRiversideSacramentoSan DiegoSan Francisco and Santa Clara. For three other counties that organize the data differently — Los AngelesContra Costa and San Bernardino — we obtained infection rates at the neighborhood and city level. We then cross-referenced those infection figures with U.S. census data showing poverty levels by community. Federal regulations set the poverty line for the 48 contiguous states at $26,200 in annual income for a family of four.
