What does a rolling 12-month median measure?

A median sale price is the midpoint of all recorded sales. Half of the homes sold for more and half sold for less. A rolling 12-month figure includes every sale in the trailing year, so each monthly update adds the newest month and drops the oldest one. The percentage changes compare each town's current figure with the same period a year earlier.

The figures include all property types. Town boundaries follow MARIS MLS's own definitions, and the data does not list the number of sales behind each figure.
