The lag

How long does a place stand before its haunting enters the record? The honest answer is that the archive almost never holds both ends of the question: 468 dossiers carry a sourced construction year,79 carry a dated first report, and 7 carry both. Those 7 are below — the whole overlap, not a sample.

What the gap measures — and what it doesn't

The longest wait in the archive belongs to Prospect Place: built 1856, first reported 2011 — the legend waited 155 years, longer than a human lifetime, before anyone wrote it down. Fairport Harbor Lighthouse ran147 years the same way. At the fast end, Orpheum Theatremanaged only 42 years between construction and the first filed story — a legend that attached almost as quickly as the plaster dried.

But read the gap honestly: first_report is when the story got filed, not when anything happened. A place built in 1856 whose first written account dates to 2011 may have carried the tale orally for decades — the field records paperwork, not hauntings. What the number actually measures is how long a place stood before the record noticed it.

The deeper finding is the absence. 468 dossiers know when they were built; 79 know when their story was first written down; only7 know both. Construction dates come from registers and plaques — institutional memory. Report dates come from newspapers, investigation logs and the occasional diary. The two kinds of memory almost never meet in the same file, which is its own quiet fact about how legends get kept.
