}About this dataset
Queensland: 77 council areas; 2021, 2026, 2031, 2036, 2041, 2046 (figures at 30 June). Current to 2046-06-30; refreshed yearly. These figures are modelled estimates.
What it is
The official projection of how many people will live in each Queensland council area, 2021 then every five years to 2046, split into five broad age bands (0-14, 15-24, 25-44, 45-64, 65 and over). The low and high growth scenarios are also given for the total.
What it shows
For each year, the projected resident population at 30 June (the total and by age band). The first year is the actual base-year estimate; later years are projections. A council area's growth is the ratio of a later year to the base year.
Why use it
Population growth drives housing demand, rents and infrastructure. Use it to rank council areas by expected growth, to see where the over-65s or the young families are heading, to size demand for a development, school, aged-care or retail site, or to put a forward-looking line on a suburb or council report.
How it is built
We take the Queensland government's own planning projections, which roll the latest population estimate forward with assumed births, deaths and migration, and match each council area to our names. These are projections, not forecasts of what will certainly happen: they assume current policy and trends, and they are revised every few years. Boundaries are the Queensland council boundaries used by the projection, so a council that is later merged or renamed keeps its projection name where we can match it. Population is by place of usual residence, at 30 June. Age bands may differ from the total by rounding. Years are one row per year with the period dated 1 January of that year; the figure is the 30 June count.
