The City of Tempe ZIP Codes feature class is from Maricopa County GIS Open Data and is intended to show the USPS ZIP Code boundaries within Tempe, Arizona.

Geospatial data about Maricopa County, Arizona Parcels. Export to CAD, GIS, PDF, CSV and access via API.

The Maricopa County Assessor static parcel maps are made available as zipped PDF files. Map IDs are broken down as Township & Range - Section - Quarter Section - Quarter Quarter. For example 807-18-04-00 would be: 807 -- Township 3 North, Range 4 East 18 -- Section 18 04 -- The SouthEast Quarter 00 -- There are no separate quarter quarter maps. MapIDs are only generated where parcels exist with Maricopa County. Last update of a MapID is indicated by the BEGIN_DATE field.

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The All Roads Shapefile includes all features within the MTDB Super Class "Road/Path Features" distinguished where the MAF/TIGER Feature Classification Code (MTFCC) for the feature in MTDB that begins with "S". This includes all primary, secondary, local neighborhood, and rural roads, city streets, vehicular trails (4wd), ramps, service drives, alleys, parking lot roads, private roads for service vehicles (logging, oil fields, ranches, etc.), bike paths or trails, bridle/horse paths, walkways/pedestrian trails, stairways, and winter trails.

Recorded subdivision boundaries for Maricopa County. Includes the Maricopa County Recorder (MCR) number and subdivision name.

The elementary school district dataset is intended to show all school districts within Maricopa County, Arizona. It is important to note the difference between Elementary School Districts, Unified School Districts and Union High School Districts. 1. When there is a Unified School District, the Elementary and High School District boundaries are the same and there is only one governing board.2. When there is a Union High School District, more than one individual Elementary School District feeds into that Union High School District. The governing board for the Union High School District and individual Elementary School Districts are separate.

These Land Use coverages were created as a joint effort of MAG (Maricopa Association of Governments) and MAG member agency staff. Land Use components were classified into 24 to 46 categories. The Land Use coverages were used for a variety of planning purposes including socioeconomic forecasting and air quality modeling.

SOURCE

This data was obtained from the Maricopa County Assessor under the search "Fast Food". The query has approximately 1342 results, with only 1000 returned due MCA Data Policies.

DATA CLEANING

Due to some Subdivision Name values posessing unescaped commas that interfered with Pandas' ability to properly align the columns, some manual cleaning in Libre Office was performed by me.

Aside from a handful of Null values, the data is fairly clean and requires little from Pandas.

NULL VALUES

Here are the sums and percentage of NULLS in the dataframe. Interestingly, there are 17 NULLS that do not have any physical addresses. This amounts to 1.7% of values for the Address, City, and Zip, and are all corresponding rows for those missing values.

I have looked into a couple of these on the Maricopa County Assessor's GIS Portal, and they do not appear to have any assigned physical addresses. This is a good avenue of exploration for EDA. Possibly an error that could be corrected, or some obscure legal reason, but interesting nonetheless.

Additionally, there are 391 NULLS in Subdivision Name accounting for 39.1%. This is a feature that I am interested in exploring to determine if there are any predominant groups. It could also generate a list of Entities that can be searched later to see if the dataset can be enriched beyond it's initial 1,000 record limit.

There are 348 NULLS in the MCR column. This is the definition according to the MCA Glossary

MCR (MARICOPA COUNTY RECORDER NUMBER)
Often associated with recorded plat maps.

This seems to be an uninteresting nominal value, so I will drop this columns.

While Property Type and Rental have no NULLS, 100% of those values are Fast Food Restaurant and N (for No), and therefore offer no useful information, and will be dropped.

I will leave the S/T/R column, although it also seems to be uninteresting nominal values, I am curious if there are predominent groups, and since it also has no NULLS, might be useful for further data enrichment.

REQUIRED: A brief narrative summary of the data set.
