The city made serious mistakes with public housing and urban renewal, although these were not the sole causes of Newark's tragedy. Across several administrations, the city leaders of Newark considered the federal government's offer to pay for 100% of the costs of housing projects as a blessing. The decline in industrial jobs meant that more poor people needed housing, whereas in prewar years, public housing was for working-class families. While other cities were skeptical about putting so many poor families together and were cautious in building housing projects, Newark pursued federal funds. Eventually, Newark had a higher percentage of its residents in public housing than any other American city.
