The most haunted states, per capita
Absolute counts reward populous states. Per-capita asks a better question: where is the record densest relative to who lives there? Below, all 3,516dossiers ranked both ways against 2020 census populations.

What the ranking actually says
By raw count the leaders are unsurprising — New York (169 dossiers), Pennsylvania (137) and Virginia (136) have the longest continuous written records and the oldest building stock in the country. More history means more paper, and more paper means more dossiers.
Per capita tells a stranger story. Excluding the territories — where tiny populations inflate the ratio — Wyoming leads the states at 111 dossiers per million residents, followed by Hawaii, Alaska, West Virginia and South Dakota. Sparse, isolated and old-mining states record disproportionately dense files: ghost towns, battlefields, institutional ground and long winter nights all compound.
The territories deserve an asterisk rather than a crown. The Northern Mariana Islands top the raw per-capita table at 296 per million — but with ~47,000 residents, a dozen dossiers move the needle more than a hundred would in Texas.
One caveat in both directions: a dossier count measures documentation, not hauntings. A state with a strong folklore-commission tradition, active preservation records and Wikipedia-documented sites will always look denser than one where the same stories were only ever told at kitchen tables. Read the table as a map of where the record is deepest — the archive's own bias made visible.
