Who lives here — how many people, how old they are, and how communities identify.
More than 41% of Tarneit residents are young adults aged 25 to 44, making it a major hub for working-age people. The area is far younger than the national average, with a typical resident aged just 30. This shift is driven by a huge number of families with children.
Tarneit has grown into one of the largest areas at this level with 56,370 people. Its typical resident is 30, which is far younger than the typical Victorian or Australian resident at 38.
Half the population is older than this age, and half younger.

Most residents are married, while 6.0% are in a de facto relationship, which is well below the national figure of 11.5%. People of Aboriginal and Torres Strait Islander descent make up 0.4% of the population, slightly below the national average.
