The city's own count
The City of Tiffin posted on April 13, 2026 that it had officially received the results of a Special Census, with a current population of 7,577, an increase of 3,065 residents from the 2020 Census (City of Tiffin, as of 2026). That count is the city's own and is not part of the Census Bureau's estimates series, so it is not directly comparable with the figures above.
