Census takers or family members may have estimated how old certain members of the household were, especially older members whose memory may not have been the best.

Ages that end in a “5” or a “0” may be approximate ages. Emphasis on the “may be.” If I find a person whose ages are relatively consistent except for that one when they are listed as 80, I tend to take that one with a grain of salt as possibly being an estimate.
