The mission of the National Marriage Project is to provide research and analysis on the state of marriage in America and to educate the public on the social, economic, and culture conditions affecting marital success and child wellbeing.
The website includes numerous HTML resources and PDF downloads, including annual "The State of Our Unions" reports and articles by the project's leading scholars: David Popenoe, Barabara Dafoe Whitehead, W. Bradford Wilcox, and others.
