In the years after the Civil War, the population of the intermountain West began to boom as people moved across the Mississippi River for new opportunities as homesteaders, prospectors, and enterprising dry goods merchants. 130 years later or so, it appears that this region of the United States is experiencing yet another renaissance. This report from the Brookings Institution's "Blueprint for American Prosperity" series takes a close look at the growth this region has experienced in recent years. Written by Robert E. Lang, Andrea Sarzynski, and Mark Muro, the report is divided into six chapters, including "Megapolitan Development in the Intermountain West" and "Forging a New Federal-Mega Agenda for the Intermountain West". Visitors can also avail themselves of a brief executive summary if they are in a hurry, and they may also wish to pay particular attention to the report's conclusions as well.
