For its recipients, Arizona’s Historic Property Tax Reclassification is a pretty great deal. Homeowners who qualify get their assessment ratios slashed from 10% to 5%, cutting their property tax bills in half. This map shows the residential properties in Pima County that receive this benefit. If you zoom in and click on an individual parcel, the map should display that property’s street address and parcel number. For a re-sizable window in a separate tab, click here.

Homeowners versus renters in Pima County

GIS By February 19, 2017 Tags: , , , 2 Comments

This map attempts to visualize Pima County’s respective distributions of residential property that is owner-occupied, and residential property that is not. The latter category consists almost entirely of rental property, but also includes a few other instances of non-owner-occupied property, such as vacation homes, certain group homes, and bed-and-breakfasts. It is represented in orange; the owner occupied property is represented in blue. To view this map in a separate, re-sizable window, click here.

Only residential property is represented on this map. Included in the white areas are public rights-of-way, government property, commercial property, agricultural property, and a number of other non-residential property types. This map distinguishes owner-occupied properties from other types based on their legal class, according to the Pima County Assessor’s records. For more information about legal classes, click here.

Libertarian presidential candidate Gary Johnson received 15,620 votes in Pima County, 3.66 percent of the total 427,102 ballots counted. Green Party presidential candidate Jill Stein received 6,200 votes, or 1.45 percent of the total. The color gradient on the maps below represents the range of vote percentages for each candidate. The darkest areas are the precincts where each did best. Johnson’s strongest showing was in Precinct 114 (Davis-Monthan Air Force Base), where he received 42 votes out of 412 cast, or 10.19 percent of the vote. Stein’s strongest was in Precinct 44 (West University and downtown), where she received 50 votes out of 1,433 ballots cast, or 4.4 percent of the vote. As with the previous presidential map, you can zoom in to see areas in greater detail. If you click somewhere on the map, statistics for that precinct (including percentages and vote totals for all presidential candidates) should display above your cursor.

This map shows each of Pima County’s 248 voting precincts with a shades of blue and red to indicate the respective degrees to which they favored the Democratic or Republican candidate, Hillary Clinton or Donald Trump. You can zoom in for a closer look, and click on any precinct for more detailed information. For a resizable version in a separate window, click here.

Although they were on the ballot, I chose to ignore vote totals for the Libertarian and Green party candidates for the purpose of this map. I also ignored write-in votes, over-voted, and under-voted ballots. None occurred in percentages that exceeded single digits, with the exception of Gary Johnson, who received 42 out of 412 votes—10.19% of the total—in precinct 114.
