While the majority of the School's faculty and staff are housed in three buildings, the School has an enormous outreach across the campus. Robertson Hall is designated as the "headquarters" of the School; Wallace Hall serves as home to several of the School's research centers as well as the Donald E. Stokes Library for Public and International Affairs and the Ansley J. Coale Population Research Collection; Bendheim Hall houses additional faculty, research, and administrative staff, as well as conference rooms and classrooms.

A building of striking contemporary design, Robertson Hall was first occupied in 1966. The building and the adjacent Scudder Plaza were designed by architect Minoru Yamasaki, who was also the architect of the World Trade Center. While intentionally reminiscent of a Greek temple, the building is cast in modern forms and uses modern construction techniques. Among its distinctive features are the 59 slender, tapered columns that are the primary support for the uppermost floor. The columns are precast in a single piece from concrete, then surfaced in white quartz. Wall surfaces of the lower floors are travertine marble, with gray glass windows. The building was named in honor of benefactors Charles '26 and Marie Robertson in 1988.

Scudder Plaza contains a reflecting pool and a sculpture, Fountain of Freedom, by James Fitzgerald. It is especially beautiful in the spring when the Pink Saucer Magnolias (Magnolia x Soulangeana) are in bloom.

Dedicated in October 2000, Wallace Hall is an innovative structure, juxtaposing granite, slate, limestone, and glass elements to form a dramatic space in which to house many of the major research centers and programs of the School. Designed by the noted architectural firm of Bohlin Cywinski Jackson, Wallace Hall is home to the Office of Population Research, the Bendheim-Thoman Center for Research on Child Wellbeing, the Research Program in Development Studies, and the Center for Health and Wellbeing.

The Donald E. Stokes Library for Public and International Affairs and the Ansley J. Coale Population Research Collection is located on the lower level of the building. The School is primarily served by the Public and International Affairs and Population Research Library, which is part of the University's extensive library system. It provides reserve materials in support of both graduate and undergraduate studies, and houses a core collection of books, journals, and research materials that supplement the research materials in the Social Sciences collection at Firestone, the University's main library.

The library's Ansley J. Coale Population Research Collection is considered the premier collection of demographic materials in the country. It contains more than 40,000 bound volumes as well as over 15,000 reprints, technical reports, manuscripts, and working and discussion papers. Sixty percent of the collection consists of worldwide statistical material (censuses and vital statistics), and it also contains international censuses through 1990 on over 4,000 reels of microfilm. The subjects encompass the areas of formal demography (fertility, mortality, and immigration), population policy, family planning, epidemiology, child and public health, and family issues.

Adjacent to Robertson Hall, Bendheim Hall houses numerous faculty and administrative staff, as well as conference rooms and classrooms. Designed by Robert Venturi '47, the building was dedicated by President George H.W. Bush in 1991.
