Comments on the Housing Stock Data
As indicated on each of the charts these data were gathered and summarized in February of 2007. The data was generated by downloading data on houses as well as condos and townhomes from the tax records data provided through the Metrolist MLS system. Properties classed as condos and townhomes in the tax records were combined into our category of “condos.” Data on the square footage of these properties (not including basement square footage) and their age were also downloaded and used to create counts of properties in our various categories. Once categorized, these properties were then mapped using ESRI’s BusinessMap software, or counted and charted using Microsoft Excel.
Our various size categories are based on the following square footage ranges. Again, these square footage counts do not include the square footage of basements or garages. On the maps, these categories are differentiated by using icons of different sizes.
Smallest: Less than 900 square feet
Small: 901-1600 square feet
Medium: 1601-2300 square feet
Large: 2301-3000 square feet
Largest: More than 3000 square feet
Our age categories are fairly self-explanatory, with the possible exception of the “<1919” and “2000+” labels we’ve used. The label “<1919” indicates homes that were built in the year 1919 or earlier. The label “2000+” indicates homes that were built in the year 2000 or later.
Houses and Condos are located on the maps using different icons, with size and age differentiated by the size and color of the icon. While thousands of properties were located on these maps — almost 40,000 in the case of Arvada for example– the size of the icons we’ve used and the scale of the maps do not allow the icons representing all of these properties to appear on the maps. Still, these maps provide a good guide to the size and age of most of the homes found in the various communities and neighborhoods represented.
