Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Bridgeport’s 0.0 sits below most of its state (28% of Illinois towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

Bridgeport is more historic than 45% of U.S. towns. The History grade combines the town’s founding era, the share of homes built before 1940 and its National Register listings. It’s a character grade, so it isn’t part of the overall grade. How it works.
25% of Bridgeport’s homes were built before 1940 (Census estimate, ±7.8 points), against a typical 11% for an Illinois town; the median home was built in 1961.
