Louisiana towns list more on the Register than most of the country (a typical Louisiana town has 3.8 per 10,000 residents, the U.S. 2.4), so Richwood’s 0.0 sits below most of its state (21% of Louisiana towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would still be D−. The pre-1940 share (±1.6 points) is firm at this size. Two sources give 1974.
