Building the case for change:
Generating evidence, driving action and improving housing globally
Housing remains a neglected priority in local, national, regional and global development commitments and foreign assistance.
Habitat for Humanity is building the case that housing is more than just four walls and a roof – it’s health, education, economic opportunity and the foundation for a better future.
Through our distinctive research initiatives, we are generating compelling evidence that positions us to take meaningful action—working alongside communities, policymakers and the private sector to drive transformative change and ensure that everyone has a decent place to call home.
