Tax-exempt municipal bonds are the primary financing tool that state and local governments use to build roads, schools, water supply systems, public and non-profit hospitals and other public infrastructure. Today there are more than $3.5 trillion in active municipal bonds from more than 50,000 individual governments.
- ICE has partnered with the University of Chicago to analyze how tax-exempt municipal bonds impact communities.
- Using a first-of-its-kind dataset, we identify the types of state and local governments that use municipal bonds, and the types of infrastructure investments financed by those bonds, across US Congressional districts.
- This analysis allows us to explore previously-unknown patterns of municipal bond borrowing and investments both within and across regions.
- This analysis is based on data from ICE municipal bond reference and geospatial data.
