William A. V. Clark

William Arthur Valentine Clark (born 21 March, 1938, in Christchurch, New Zealand) is Distinguished University Research Professor in the Geography Department at the University of California, Los Angeles. His research focuses on housing markets and residential mobility and migration, and the impacts of local residential change on neighborhood outcomes, including segregation and ethnic and racial patterns.

After joining UCLA in the 1970s, Clark taught and conducted research there for the next four decades. In 2018, he was awarded the Edward A. Dickson Award from the UCLA Emeriti Association and the Lifetime Achievement Honors of the Association of American Geographers. He is an Elected Fellow of the American Academy of Arts and Sciences, an Elected Honorary Fellow of the Royal Society of New Zealand and a member of the National Academy of Sciences.

Clark completed his bachelor’s and master’s degrees at the University of Canterbury, then a constituent college of the University of New Zealand. He was awarded a Fulbright Fellowship to attend the University of Illinois, Urbana and received his PhD in geography in 1964. He returned to teach at the University of Canterbury, New Zealand for two years between 1964 and 1966.

Clark then returned to the US to take up an assistant professorship at the University of Wisconsin-Madison. He received tenure in Geography and Planning but resigned in 1970 to move to the Geography Department at UCLA, where he taught and conducted research for four decades. In 2010, he became a Distinguished Research Professor (Emeritus) at UCLA.

He has been the editor of Geographical Analysis (1984–1987), Environment and Planning A (1988–1998) and consulting editor of Tijdschrift voor economische en sociale geografie, (1985–1988). He is a member of the editorial boards of Geographical Analysis and Population, Space and Place.

Contributions

Clark's research papers have formally tested the Schelling model of choice and showed that the theoretical tolerance distributions outlined by Schelling, could be generated from survey data. A second set of research papers showed how the life cycle generated residential moves and neighborhood outcomes.

Throughout his career, Clark participated in many desegregation court cases studying the racial and ethnic separation patterns around the United States. These studies were stimulated by a question posed by Lewis F. Powell Jr. in the Detroit desegregation litigation (Milliken v Bradley, 1974) – "how can we understand the patterns of ethnic and racial segregation in US cities." The court hearings gave an opportunity to bring geographic and demographic findings about segregation and separation into the court room. Demographic research on the issues of residential segregation and selection was presented in these presentations: Armor v Nix (1979), Dowell (Oklahoma), Freeman v. Pitts (Georgia), Riddick (Norfolk Virginia), Jenkins (Kansas City), and Capacchione vs Charlotte-Mecklenburg (North Carolina). As the court reported in their review of Freeman v Pitts, “when residential segregation occurs as a result of private choices it is beyond the authority and also the ability of federal courts to address these private decisions and the impact of continuing and ongoing demographic changes.”

Clark was awarded a Fulbright fellowship in 1961 to study in the United States and later received the Honors Award of the Association of American Geographers in 1987. He held the Belle Van Zuylen Professorship, University of Utrecht, The Netherlands in 1989 and was awarded the Doctorate Honoris Causis (Honorary Doctorate), University of Utrecht, The Netherlands in 1992, and a DSc (Doctor of Science) from the University of Auckland, New Zealand in 1994.

Clark was awarded a Guggenheim Fellowship in 1994 and elected an Honorary Fellow of the Royal Society of New Zealand in 1997. In 2003 he was elected as a Fellow of the American Academy of Arts and Sciences and in 2005 to the National Academy of Sciences and in the same year received theDecade of Behavior Research Award. The College of Letters Arts and Sciences of The University of Illinois awarded him the Alumni Achievement Award in 2006.

Clark's recent honors include the 2013 Lifetime Achievement Award of the Population Specialty Group from the Association of American Geographers, a 2014 Benjamin Meaker Research Fellowship from Bristol University, the 2015 Distinguished New Zealand Geographer Medal by New Zealand Geographic Society and the2018 Lifetime Achievement Honors of the Association of American Geographers. He received the 2018 Edward A. Dickson Award from the UCLA Emeriti Association.
