About the International Downtown Association
Founded in 1954, the International Downtown Association (IDA) connects diverse practitioners who transform cities into healthy and vibrant urban places. Representing more than 3,000 practitioners across 500 organizations worldwide, from cities and towns both small and large, IDA provides the critical tools and resources to help make every downtown a healthy and dynamic heart of its community. As expectations grow for downtown practitioners to transform their cities into hubs of economic and cultural vibrancy, IDA is the organization professionals turn to for the industry’s best networking, educational, and professional development opportunities.

About the Center City District
The Center City District (CCD) is a $20 million, private-sector sponsored business improvement district authorized under the Commonwealth of Pennsylvania’s Municipality Authorities Act. Covering 233 blocks in the heart of downtown Philadelphia, the CCD helps create a clean, safe, attractive, and well managed public environment in order to support business and economic development in Center City Philadelphia. In addition to public space management and services, the CCD also conducts extensive public policy and market research.
