Map 3: Student Loan Borrowers 90+ Days Delinquent, San Francisco Bay Area, March 2018

This map shows percent of student loan borrowers in delinquency (defined as 90+ days late on payments) by zip code. The darker areas of the map indicate zip codes with higher levels of delinquency. Having a delinquency reported to credit bureaus will lower a borrower’s credit score and negatively affect their finances. Highest delinquency rates are almost uniformly found in low-income neighborhoods. This map and the others linked below are a supplement to the April 2019 Report, At What Cost? Student Loan Debt in the Bay Area, written in partnership with the San Francisco Treasurer’s Office of Financial Empowerment. For full findings and analysis.

About the Data

These maps employ Federal Reserve Bank of New York Consumer Credit Panel/Equifax Data from March 2018 going back to March 2003 and the American Community Survey (ACS) 2013-2017. Collected quarterly by the credit bureau Equifax, these data comprise various credit and demographic characteristics of an anonymized 5 percent national random sample of consumers over 18 with a credit history and Social Security numbers. We adjusted balances to account for jointly-held loans. We defined delinquency and default in accordance with the Department of Education definitions of being 90+ or 270+ days past due on one or more student loan, respectively. We excluded zip codes from the analysis if they are missing Census or ACS data or from maps if they have fewer than 10 observations. See the full report for more information on methods.
