Andrei Rogers


Andrei Rogers is Emeritus Professor of Geography and Senior Research Associate in the Population Program at the Institute of Behavioral Science. Since obtaining his Ph.D. in city and regional planning at the University of North Carolina, Chapel Hill, he has held faculty appointments in the Department of City and Regional Planning at the University of California, Berkeley, and the Department of Civil Engineering at Northwestern University, Evanston, Illinois. Before his move to Colorado in 1983, he spent eight years at the International Institute for Applied Systems Analysis (IIASA) in Laxenburg, Austria, where he headed a research program that addressed global human settlement problems and issues. He moved to Boulder, Colorado in 1983 to take on the job of Director of the Population Program, stepping down after 20 years in 2003. He is the author of ten books on various aspects of population analysis. His current teaching and research interests revolve around the topics of immigration, internal migration, population geographies, and urbanization.

In 2000, Professor Rogers received the Walter Isard Award for Distinguished Lifetime Scholarly Achievement from the North American Regional Science Association, and in 2003 he was awarded a faculty fellowship from his university to enable him to devote full-time research on migration for a year. In 2006 he was included in a group of senior international scholars deemed to have contributed to the quantitative revolution in human geography in the 1960s, and was invited to participate in sessions dedicated to this topic at the July 2006 International Geographical Union Regional Congress in Brisbane, Australia (The Legends of Quantitative Geography, Geographical Analysis, 40, 2008 entire issue.)

Current Research

During the past years Professor Rogers has been conducting research in three principal areas: immigration and the regional geography of the foreign-born population in the United States, elderly migration and settlement patterns, and the indirect estimation of migration. Imagine the geography of the foreign-born population in the United States at the middle of this century, and imagine its changes since then. How did the demographic processes of immigration, emigration, internal migration, and mortality act to shape the changing geography? How did the fertility patterns of foreign-borns and native-borns combine with the migration and mortality patterns of the latter to shape the geography of the native-born population and the consequent foreign-born shares of regional populations? How have the internal migration patterns of the foreign-borns differed from those of the native-born population? How have the internal migration patterns of the elderly differed from those of the non-elderly populations? Assisted by several graduate and undergraduate students, Professor Rogers has been seeking answers to such questions by modeling the spatial population dynamics of sub-populations in the United States during the past half-century.

Although the principal focus of the multi-year studies of the foreign-born and elderly populations have been their interregional migration and spatial redistribution in the United States, the absence of adequate data on territorial mobility--for example, on emigration--necessitated some of the estimates of some migration streams to be made indirectly. In the process new methodological approaches had to be explored and tested for the first time, drawing on the emerging literature on the statistical analysis of data with missing values. Some of the results were presented at a workshop on the indirect estimation of migration that was convened in Estes Park in early 1999, leading to the publication of a special issue of Mathematical Population Studies edited by Professor Rogers and devoted to this topic. This was followed by a short course on indirect estimation offered by Professor Frans Willekens of the University of Groningen in The Netherlands in July (PowerPoint presentations to accompany the course on "Loglinear Modeling and Missing Data" are available for download), and the receipt of two grants from the National Science Foundation to support current collaborative work on this topic. Several articles published in 2001-2007 describe some of the findings of this research. A National Institutes of Health (NIH) funded conference on this topic was convened in September of 2004; the papers are available for downloading from website: A research grant from NIH provided the funding for continuing this work. A book, "The Indirect Estimation of Migration", was published in 2010 (see below).
