This special issue of Community Investments highlights excerpts from a new book published by the Federal Reserve Bank of San Francisco and the Low Income Investment Fund titled Investing in What Works for America’s Communities: Essays on People, Place & Purpose, with a particular focus on the topic of “integration," a prominent theme that emerges from the book. The most promising models of community development going forward all include elements of integration, such as layered financing, joint development, shared accountability, or coordinated services. The authors argue that the dichotomy of “people versus place” and the rigid siloes separating housing, education, health, and other sectors must become a thing of the past in order to effectively address poverty in the future.
