Nikiski first appeared on the 1880 U.S. Census as the unincorporated Tinneh villages of "Kultuk" (AKA Nikishka No. 3) and "Titukilsk and Nikishka". Kultuk had a population of 17, and Titukilsk and Nikishka had a population of 57,  all of whom were Tinneh Natives.  There apparently were no census reports from 1880 until 1980, when the area was organized as "Nikishka" and made a census-designated place (CDP). The name was altered to "Nikiski" in 1990 and has reported as such on each successive census.
