Data

Pima Association of Governments produces data to guide regional planning by member jurisdictions and makes much of that data available for public use.

Access to data is important to support informed decision making across the region and beyond. PAG is a regional data center that offers services to members and others to access a variety of data that is developed in-house. This information is made available to the public, our stakeholders and employers in the region for a fee for services. We are happy to help address any questions you may have about the data or services we offer.

Orthophotos and LiDar

Pima Association of Governments makes its orthophotos and LiDar available for purchase. Orthophotos are aerial images that are geometrically corrected to have uniform scale. Data are available for the years 1998, 2000, 2002, 2005, 2008, 2011, 2015 and 2021.

Arizona Sun Cloud Data Portal

Working in collaboration with Maricopa Association of Governments and the other agencies of the Sun Corridor megaregion, Pima Association of Governments has made available a dataset designed to assist in many areas of urban planning.

This collaborative effort will assist communities large and small to make data-driven urban design and infrastructure planning decisions and better serve their residents.

The new datasets, incorporated into the Arizona Sun Cloud Data Portal, provide users with interactive maps and built-in tools to assess the connections between data layers, and add customized scoring weights to prioritize municipal planning efforts. The open data portal provides access to transportation and socioeconomic data throughout an area more than 31,000 square miles.

Representing Cochise, Maricopa, Pima, Pinal, and Santa Cruz counties, Arizona’s Sun Corridor is home to about 85% of the state’s residents. The region’s population is expected to grow 40% by 2050. Such rapid growth produces complex challenges in community planning that require geospatial analysis, particularly when it comes to transportation.

Traffic Data

PAG performs or collects annual traffic counts throughout eastern Pima County to support transportation planning decisions. Find out more about PAG’s traffic count data collection and access the traffic count map on the Traffic Data page.

Roadway Construction Standards and Specifications

As the metropolitan planning organization for the greater Tucson region, PAG publishes a Standards and Specifications for Public Improvements document to guide consistent roadway construction implementation across jurisdictions. Regional stakeholders can access the Roadway Construction Standards and Specifications document and an order form for print or digital copies. Copies of the edition may be ordered through Arizona Lithographers. Purchases are made through Pima Association of Governments.

Performance Measures

Performance measures help gauge progress toward long-range regional transportation goals and are used to communicate strategies to change outcomes. PAG’s performance measures are meant to be applied throughout the region to improve mobility, sustainability and livability.

Travel Reduction

Employers with 100 or more full-time equivalent employees are required to participate in Pima Association of Governments’ Travel Reduction Program. TRP employers are required to conduct an annual employee survey to collect employee travel patterns. This data is used for transportation planning and development strategies to reduce congestion and improve air quality in the region. PAG provides support to employers to conduct the survey and consults with employer transportation coordinators to encourage employee use of alternative modes of transportation. Ridesharing assistance is available through PAG’s Sun Rideshare program.

Regional Population Overview

The greater Tucson region includes six jurisdictions and two tribes, and they are members of Pima Association of Governments. The population of each local government is based on 2020 Census results. The regional population overview information provides a snapshot of the region’s expanse and diversity.
