Ninilchik first appeared on the 1880 U.S. Census as an unincorporated Creole (Mixed Russian and Native) village. All 53 of its residents were Creole. It returned in 1890 with 81 residents, however the census combined the adjacent locales of the Laida native village and Anchor Point mine along with Treadwell coal mine (not to be confused with the Treadwell that is now within Juneau). There were 53 Creole residents (probably all Ninilchik residents), 16 Natives (probably the Tinneh residents of Laida), and 12 Whites (probably the residents of the two mining locales). Ninilchik did not return again until 1920, when it was spelled as “Ninilchic” on the census. It returned as Ninilchik again in 1930, and in every successive census to date. It was made a census-designated place (CDP) in 1980.
