With the development of the Bakken oil play in eastern Montana and western North Dakota, population change in the region is highly contingent on oil development and activities supporting the oil industry.


In an effort to account for potential effects increased oil development may have on the population in eastern Montana counties, CEIC has incorporated the work of the Montana Department of Transportation’s (MDT) Planning Division related to impacts of future oil development on the defined 16 county region with eREMI baseline county level projections.


Please refer to the Eastern Montana Population Projections - Methodology for a detailed explanation of the process for allocating MDT’s analysis on the entire region to each of the 16 counties within the region using eREMI county level population projections.
