State of the Economy Series

In January 2024, the Office of the Comptroller released the inaugural State of the Economy (SOTE) Report that examined economic trends in Maryland compared to the U.S. and neighboring states. This report has been followed by a series of SOTE briefs that further examine key topics and findings from the original report to inform policymakers and the public.

State Spending Series

For Maryland to prosper and thrive in the 21st century, it needs to build more. The state needs more transit, climate resilience infrastructure, housing, schools, and industrial facilities.

This series explains state expenses and shares lessons learned from across the U.S and world about cost drivers of public goods projects that are essential to inclusive growth.
