DATA NOTES
Sales data is sourced from the NSW Valuer General bulk data files. It includes registered property transfers — houses, units, vacant land, and commercial properties. Rental figures are derived from postcode-area rental market observations and are clearly separated from suburb-level sales figures. Median is used throughout as it is less sensitive to outliers than the mean.
