On July 21, 2023, the OMB delineated three combined statistical areas, six metropolitan statistical areas, and four micropolitan statistical areas in Maryland. As of 2023, the largest of these is the Washington-Baltimore-Arlington, DC-MD-VA-WV-PA CSA, comprising Washington, D.C. and its suburbs as well as Maryland's largest city of Baltimore.

Primary statistical areas
Primary statistical areas (PSAs) include all combined statistical areas and any core-based statistical area that is not a constituent of a combined statistical area. Of the 13 statistical areas of Maryland, four are PSAs comprising three combined statistical areas and one micropolitan statistical area.
