Washington DC is the center of the nation's ninth largest metropolitan area (PMSA), home to 4.4 million people and 2.9 million employees in a web of 25 separate, autonomous municipalities spanning three states and the District of Columbia. As such, the region is a good place to analyze the pattern of suburbanization of producer service employment over the past 25 years. In addition to overall suburbanization, the metropolitan area has seen changes in the nature and role of its dominant economic force, the federal government. Direct federal employment has stagnated while federal contracts to private companies have soared. Producer service employment seemed to increase in importance in jurisdictions away from the region's core, simultaneous with increases in total employment, following increases in federal contracting, and independent of increases in federal employment. These trends have affected the growth of producer service employment across the metropolitan area, encouraging their suburbanization. By subjecting our initial models to sub-sector data and analysis of temporal trends in the coefficients, we uncover the uniqueness of legal services and additional evidence of suburbanization over time.his paper focuses on producer service employment within a metropolitan T area: more specifically, the geographic variation in the nature and growth of that employment across the metropolitan area over time. As the businesses and households they serve-as well as increasing proportions of their professional, technical, and even clerical labor force+have suburbanized, so too have producer services. Though the spatial and temporal paths of producer service suburbanization have not been widely studied, the sprawling and rapidly growing metropolitan Washington area provides a good general case of those temporal and spatial dynamics. Since the 1960s, widespread suburbanization
