Charles Colgan is an economist, policy analyst, and faculty member at the University of Southern Maine’s (USM) Muskie School of Public Service. Colgan’s research examines employment trends, transportation needs, income discrepancies related to economic development, and the spatial distribution of economic and population change in Maine and in U.S. coastal regions. Before coming to USM, he served for 12 years in the Maine State Planning Office, including in positions as Maine State Economist and Special Assistant to the Governor for International Trade.

Colgan’s research with the Mitchell Center focuses on urban landscape change in Maine in the metropolitan regions of Portland and Bangor. Colgan’s team is building large-scale computer simulation models of these two regions using software that transforms the interactions between land use, the economy, transportation, and the environment into visual representations. Colgan uses these models in his work with stakeholders to examine the sustainability effects of scenarios that represent policy choices facing these metro regions in the future. The project’s emphasis on the importance of models as predictors of change has allowed students the opportunity to actively participate in the research process. His research has resulted in the report “Changing Maine: Maine’s Changing Population and Housing 1990-2010” and a companion volume focused on Southern Maine.

Colgan’s research has been funded by the Bureau of Labor Statistics, Maine EPSCoR, National Science Foundation, and the Senator George J. Mitchell Center.

Colgan has been quoted in regional newspapers, magazines and television stations. His research has been published in several journals including Ocean and Coastal Management, Growth and Change, and the Maine Policy Review. He is the editor-in-chief of the Journal of Ocean and Coastal Economics.
