Warren grew from 435 to 39,201 between 1820 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

Museums hold 241 specimens collected within 10 miles of Warren between 1890 and 1975: 193 Animalia, 40 Plantae, 4 Fungi, 2 Protozoa, 2 Chromista. 12 distinct Species records are shown. Collected by A. N. Rood, Almon N. Rood, Armbruster, D. C. (Daniel C.) and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.

The federal mineral resources record lists 4 workings within 5 miles of Warren: 3 producers, 1 plant. All of them still produce. What was taken out: Iron, Titanium, Metal. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.

2 papers published in this town, digitised by the Library of Congress and free to read: 0 issues, 0 pages. Every page is searchable, so a name or a street can be looked for directly in what the town printed about itself at the time.

Front pages of the local paper, read from the Library of Congress scans: 10 issues spread across its run from 1855 to 1873, 60,903 words in total. Each is reproduced on its own page, exactly as the recogniser returned it.

These pages read less well than anything else here, and the number is worth stating: about three words in four come through cleanly, against nine in ten for the building records. An 1896 broadsheet sets eight-point type in seven columns on microfilm, which is the hardest thing in this archive to read by machine. We tested our own recognisers against the Library's and they were not better, so the Library's text is what appears, with the wholly unreadable columns removed. Read it as a guide to what the paper covered, and follow the link to the scan before quoting anything.

The eight closest, with where each one stands in the county. Distances are straight-line, computed from the Geographic Names Information System coordinates.

Matched on this settlement's Geographic Names Information System number rather than its name, so it cannot be a different place of the same name in another state.
