HistoryA character grade: shown, never part of Oakdale’s overall grade.
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 Oakdale’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.
