This paper was written with the intention of providing estimates of the regional demographic and economic impacts of current and proposed federal policies, identifying the most important audiences for this type of data collection, and addressing the research design for this project. The Rural Policy Research Institute’s need for sixteen models for county groupings from REMI was detailed to show what separates REMI’s models from other similar products and the specific requirements requested by the Institute. The study then continued to describe how the REMI model incorporated the federal budget, utilized a baseline solution, and considered alternative policies.
