- Each circle represents a metropolitan Phoenix zip code.
- The size of the circle reflects the number of homes sold in the zip code in December 2010.
- The color of the circle reflects the median price per square foot of homes sold in the zip code in December 2010. The darker the red, the higher the median price per square foot.
- Hover over a circle to see the data for that zip code.
What caught my eye were the large number of sales in Gilbert and also Chandler.
Remember that zip codes vary tremendously in size. Some have many more homes than others. That means a large circle may just represent a large zip code, not necessarily that homes are selling well in that zip code.
Note regarding home sales less than $10,000. When I calculate sales and median prices, I discard sales below $10,000. Years ago I assumed they were typographical errors, however, some homes in very inexpensive areas are indeed selling now for under $10,000 so my data will under estimate the number of sales and over estimate the median price per square foot in those very inexpensive zip codes.
