The Zip Code Exam turns national health data into hyper-local blueprints for change by integrating physical, digital, and civic engagement. At its heart is a provocative truth: your zip code can predict your life expectancy more than your DNA. The data-powered campaign launched with stark OOH messages placed between neighborhoods where life expectancy dropped dramatically. On zipcodeexam.com, residents could view and compare their score, download a personalized Community Health Report, and email it directly to local leaders. More than a campaign that made invisible inequalities visible, the Zip Code Exam empowered communities to take health into their own hands.
