Middle Neighborhoods (MNs) are generally recognized for their safety, stability and affordability for residents. They also provide an important opportunity to give lower-income populations access to affordable housing and an overall higher quality of life, but the number of MNs is declining throughout the U.S. Recognizing these opportunities and challenges regarding MNs, the research team set out to fill in the existing knowledge gaps about which public policies and programmatic activities are effective at 1) stabilizing MNs and 2) providing equitable access for lower-income and marginalized populations to join and stay in MNs.
