Strawberry Shortcake

Your hypothesis is a good one, but with one important qualification.

If by “most saturated” you mean the greatest concentration of NPR-affiliated stations per square mile, then Michigan’s Lower Peninsula is certainly among the most densely served regions in North America, especially because so many stations are licensed to universities. However, it is probably tied with or slightly behind a few regions such as New England and parts of North Carolina.

Lower Peninsula Michigan is unusual because of its university-based network

Within a day’s drive you can receive programming from numerous university-affiliated public radio stations, including:

Michigan Public itself operates a five-transmitter network serving roughly 80% of the population in the southern Lower Peninsula.

Other highly saturated regions

Some other areas rival Michigan:

1. Boston–Providence
   • WBUR (Boston University)
   • GBH
   • Rhode Island PBS/Radio
   • several nearby New England stations
2. North Carolina Research Triangle
   • WUNC (UNC)
   • WFDD (Wake Forest)
   • WNCU (North Carolina Central)
   • plus several statewide public radio services
3. Northern California
   • KQED
   • KALW
   • KCSM (College of San Mateo)
   • KCRW and others farther south
4. Minnesota
   • Minnesota Public Radio’s statewide network
   • university stations
   • strong regional overlap

Michigan’s distinctive feature

Michigan differs from most states because so many NPR member stations originated at public universities. The combination of:

• University of Michigan
• Michigan State
• Eastern Michigan
• Western Michigan
• Central Michigan
• Northern Michigan
• Grand Valley State
• Delta College

creates one of the largest concentrations of higher-education public broadcasting in the United States.

For your StandardsMich readership, an interesting observation is that this concentration reflects Michigan’s long-standing investment in public higher education. Few other states have such a dense network of university-affiliated public radio stations whose coverage areas overlap across a single peninsula. While it is difficult to declare a single “most saturated” NPR region without a formal coverage analysis, the Lower Peninsula of Michigan is a strong candidate and is almost certainly among the top few regions in North America.
