Total Income Clusters
2015 Census Adjusted for Density
GIS mapping facilitates combining multiple layers of
discrete data. This month, we have combined the number of households by median
household income divided by the number
of square miles and color-coded total household income by census tract;
after adjusting for population density.
As seen, there are at least five “clusters” which represent
the highest total incomes. Sometimes this may be a proxy for other data points
such as disposable income, housing prices, and schools.
In no order, the five clusters that pop out are:
Scottsdale near Scottsdale Fashion Sq.
The Islands area in Gilbert
North Phoenix south of 101 and Tatum

Median Sale Price Range by Top Ranked Schools
Maps & Facts
researched the 2016 AzMERIT scores for the Top Metro Phoenix Elementary and High
Schools. Eight (8) top Elementary Schools
were paired with five (5) top High Schools. We then calculated the Median Sales Price for
each Elementary School’s attendance boundaries. The median is the midpoint of all sales (not
the average). By definition, half the
median sales are below the median price and half are above.
The attached chart
summarizes our data. Because 2016 median
was about $240,000, we have also included the high and low prices for each
school. As shown, affordable price
houses are available in most of these elementary school districts.

Family Appreciation Update: +4.25%.
Most year-over-year appreciation
surveys can vary dramatically from year-to-year because the data often includes a wide mix of all houses,
of all ages, of all sizes, of all prices, for all extremes (including outliers)
– hardly apples with apples.
Maps & Facts Unlimited tracks
the price pattern of a representative house; not the entire mix. For each year
since 2001 Maps & Facts Unlimited has tracked sales of
single-family houses built between 1990 and 1999 which sold between $100,000
and $1,000,000. I.e. How has the median appreciation rate for our
representative house changed since 2001; and more importantly today, since
The chart below tracks 15 years
of price changes. Based on over 15,000 sales, the median sale price in 2016 was
$270,000; 4.25% higher than 2015. The chart also shows that the median sales price
is still well below the $302,000 peak in 2006.
On the following 2016 map, the
red dots represent the locations of the 2016 sales. When we compare each year’s
dots*, their locations are virtually identical.
Apples with Apples!
