Leadership and longevity in Philadelphia's neighborhoods

A tracked history of the Community Development Corporations behind Philadelphia's commercial corridors and affordable housing. Who runs them, how big they are, how long they last, and the moments leadership changed hands.

Research question. What factors determine leadership transitions in community economic development organizations in Philadelphia?
In plain terms

What a CDC isA Community Development Corporation is a neighborhood nonprofit that works to keep one part of Philadelphia healthy, fixing up housing and bringing storefronts back to life along the local commercial corridor. Most run on grants and public money, with a single director often setting the direction.

What we trackCorridor keeps a running record of these groups across the city: who runs each one, how much money it takes in, how many people it employs, and how many years it has filed with the IRS. When a budget jumps or a leader changes, it turns up in the data.

What it's forThe aim is to make it easy to see which neighborhood organizations are steady and which may be at a turning point, so residents and the funders behind them can act with a clearer picture.

Acronym-named and fiscally sponsored organizations are left unmatched rather than tied to a wrong EIN. A wrong match would quietly corrupt the data.
