I recently attended a seminar that looked at spatial patterns of a particular CALD community in Melbourne. The presenter expressed surprise at the age structure as there were very few children born in this particular country. To me, it was a classic example of "traps for young players" when analysing Census data on CALD communities. They are generally measured by birthplace, ancestry and language, but the size of the community will differ depending on the variable used. With the release of 2021 Census data later this year, it's worthwhile revisiting this topic ahead of time.
