Abstract
Military expenditure is the largest category of discretionary spending in the US federal budget. As such, its spatial patterns are also among the most concentrated. An analysis of recent defense spending data indicates that ten to fifteen states receive between them at least 70% of military contracts, and higher proportions of high-technology and research-related contracts. Examination of subcontracting data reveals that little wider dispersion of defense spending occurs to states outside the core areas in the West, on the East Coast, and in a few interior locations.
