Title : What is a preliminary median and why is the final median different?

When REIWA publishes its initial figures on reiwa.com and in the Property Report, it is important to understand these are preliminary medians as they are based only on a proportion of the data available, generally around 65 per cent for the most recent quarter.

As the balance of the data is received from the Landgate Information over the subsequent months after the initial release, in many case the median whether it be for the quarter or for the year will invariably change, hence the subsequent publication of final medians when the next quarter is released.

For example, in the March Quarter 2006, Perth's preliminary median for the quarter was $353,000 but as the balance of the records are added from the latter part of the quarter, the final median for the March Quarter increased to $365,000.

Factors influencing an increase between preliminary and final medians include:

  • more affordable properties often have shorter settlement periods, hence the data is received earlier, and
  • in a rapidly rising market as experienced during 2005-06, prices increase monthly and therefore later records are generally of a higher value.
