Aviston has since become one of Clinton County's growth stories: its population surged 58% in the 2000s alone, from 1,231 in 2000 to 1,945 in 2010, and the Clinton County comprehensive plan singles out Aviston among the western communities feeling growth pressure from the St. Louis Metro East.

Aviston had a population of 2,340 at the 2020 census, up 20.3% from 2010, making it one of the fastest-growing small villages in southern Illinois.

Aviston covers 1.60 square miles, all of it land, at a population density of about 1,462 people per square mile.

Aviston's youngest residents attend Aviston Elementary School in Aviston School District 21, which enrolls roughly 400 students.

Census Bureau survey estimates put Aviston's median household income at about $117,875, with a homeownership rate of about 81.7% - well above the national average - reflecting its popularity with commuting families.
