Planning Research
The Research Section is responsible for demographic, housing, land use, and economic data collection and tabulation. The section performs data-driven analyses and policy-relevant research for Planning Department leadership and staff, county officials and agencies, businesses, and residents to formulate sensible plans and programs for maintaining or enhancing community vibrancy. Moreover, the Research Section updates population, housing, and employment forecasts in coordination with the Metropolitan Washington Council of Governments and Maryland State Data Center. In addition, this section is the primary liaison to the U.S. Census Bureau in support of their programs related to the decennial census, the American Community Surveys, and other initiatives.
