Habitat for Humanity is a global nonprofit housing organization that works in local communities across all 50 states in the US and in approximately 70 countries. Founded in 1976 by Millard and Linda Fuller, the organization aims to provide affordable housing to families in need, believing that a decent place to live is crucial for strong and stable communities.

Habitat for Humanity operates by partnering with families who contribute "sweat equity" by helping build their own homes alongside volunteers. These families then pay an affordable mortgage. The organization also advocates for policy reforms to remove systemic barriers preventing low-income and historically underserved families from accessing adequate housing.

Since its inception, Habitat for Humanity has helped more than 59 million people improve their living conditions. The organization works with local communities, volunteers, and partners worldwide to ensure that more people have access to safe and affordable homes. In addition to building homes, Habitat for Humanity engages in various initiatives such as disaster response, microfinance, and water, sanitation, and hygiene (WASH) projects.

Despite criticisms regarding safety, cost-effectiveness, and the selection of partner families, Habitat for Humanity remains one of the largest homebuilders in many areas, receiving numerous awards for its work in building quality homes. The organization's commitment to affordable housing and community development has made it a significant player in addressing global housing needs.
