1. Which browsers are officially supported by the Esri Redistricting software?

Safari, Firefox, MS Edge, and Chrome.  IE 11 will not be supported moving forward.

2. Can I use my own boundary for my Redistricting process, or do I need to use the standard Census data?

  • No, if using the single-seat (SaaS) implementation via ArcGIS online, however you can use your custom data as reference.
  • Yes, if using the on-Premise or Managed Cloud Services version; the data can be customized to fit your redistricting solution as needed.

3. If using a Managed Cloud Services Redistricting solution, what is the standard infrastructure for a single server setup?

  • Standard data storage is up to 500 GB
  • Single cloud ArcGIS Server with 4 virtual computing units and 32 GB of Virtual memory
  • Hosting period 12 months
  • Up to 100 active users
  • Target system availability = 95%
  • Full weekly backups (incremental daily backups)
  • Long term backup for 30 days
  • Daily syncs with your data into your Cloud instance
  • Microsoft Windows Server 2016 (or newer) operating system
  • ArcGIS Enterprise licensing
  • System Monitoring 24/7 with Esri COTS hosted software
  • Operation support 24/7 from MCS

4. What is the advantage of using Esri redistricting solution vs. competitor software?

  • Esri's Redistricting solution is a web-based solution that requires no software installation and is scale-able based on total users.
  • Esri’s Enterprise Redistricting solution allows public participation in the redistricting process to ensure full transparency to the public.

5. Can a "Plan Population" summary report be exported to CSV or other formats for additional analysis? 

  • There is not an "export to CSV" option; however, you can export to an Excel file, then "Save as" CSV".
  • Other export formats are available such as HTML, PDF, and Excel files. 

6. Can all plans be exported to shapefile and block equivalency files all at once?

  • No, there is no bulk export of shapefiles or block equivalency files function.
  • Only single exports of each redistricting plan are available currently. 

7. Can I use my existing ArcGIS Online account for the Redistricting trial software?

  • No. To use the free 21-day trial, you need to create a new ArcGIS Online account using the activation email you receive after submitting the form.
  • If you want to use an existing ArcGIS Online account, please reach out to your Esri Account Manager and/or customer service representative and request to activate a Redistricting evaluation and provision licenses to the app via ArcGIS Online.

8. What is the difference between the free Districting for ArcGIS ArcMap extension vs. the Esri Redistricting SaaS option? 

Districting for ArcGIS

Esri Redistricting SaaS version

Requires ArcMap

Up-to-date web browser

Not menu driven – no UI

Robust UI specifically for political redistricting.

Does not ship with Census P.L. data

Comes with past and current P.L. 94-171 data

Required GIS background and experience

GIS experience not required

Can work with other polygon data, such as work zones, school attendance zones, Police Beats.

Is locked to P.L. data.  Can create other districts but only based on Census geography.

Free, but requires ArcMap

SaaS pricing = $4,500

Users must provide their own data to complete a district plan or boundary

Access to Esri Living Atlas and ArcGIS Online via Esri Redistricting app

No Esri support or active product development

SaaS version has Esri support included


9. Does Esri Redistricting handle a large number of users if my jurisdiction requires public participation (ex: 2000 users)?   

The foundation of Esri Redistricting resides upon ArcGIS Enterprise. The Esri Redistricting solution was designed such that the browser client does most of the heavy lifting which reduces the load on the ArcGIS Server in the background. Because of this, the Esri Redistricting application won't be the bottleneck in the system architecture. If there is concern over the number of users accessing the software, it may be suggested that an additional 4-core server be included to allow your system to auto-scale if necessary.

Esri provides software and services needed to help you set up Esri Redistricting and develop your staff capabilities. Several options are available for delivering the necessary enablement services through implementation services and technical knowledge transfer.


Esri Redistricting can be deployed in three ways depending on your organization’s needs. For each deployment option, you can request additional days of onsite training and knowledge transfer for your organization. Note that, the implementation approach provided below can be adjusted to meet your specific needs.


     The Esri Redistricting application includes a host of integrity checks and reports for analyzing potential redistricting plans


Option 1: Software‐as‐a‐Service (SaaS)


When you deploy Esri Redistricting as a SaaS solution, you can access Esri Redistricting in the cloud, entirely hosted and maintained by Esri. You don’t need to install or maintain any software or hardware—instead, you simply log in to your ArcGIS account in a web browser. The SaaS option provides access to all functionality of the solution, including the default Census demographic data, geographies, and the ability to add content from accessible ArcGIS web services. 


The SaaS version of Esri Redistricting is available for purchase on a per-user basis from ArcGIS Marketplace with a 15-day free trial option.


 Option 2: On‐Premises Deployment


With this option, Esri Redistricting is hosted at your facility, giving you the flexibility to integrate custom variables, units, or demographics. Prior to arriving onsite, Esri Professional Services experts will work with your team to pre-configure appropriate Census data, your custom data, and other configuration parameters. Once onsite, our experts will install and configure the solution stack on your infrastructure, conduct a technology transfer for administrators who are qualified to manage the Esri Redistricting application, and help facilitate ongoing support and maintenance of the solution.


The instance will be hosted and managed by you. You have full control over adding users, customizing the solution, and managing the application.

Redistricting plans must comply with provisions of the federal Voting Rights Act of 1965 for covered jurisdictions and specific state laws regarding the creation of legislative, congressional, and other elective districts. 

Esri Redistricting assists state and local governments in drawing legislative and congressional redistricting plans using Census data, including plans for data from the upcoming 2020 census. In addition, advocacy groups and the general public can use the online Redistricting solution to evaluate proposed plans, provide input to decision‐makers, and collaborate with others to develop alternative plans for consideration. You can rapidly and effectively create, edit, publish, review, and collaborate on redistricting plans that comply with federal law through a robust, easy-to-use web-based application.

Esri Redistricting addresses common needs and challenges related to redistricting at the state and local level within the U.S. The foundation of this product is Esri’s proven ArcGIS platform and pertinent data set components. Powered by the ArcGIS platform, Esri Redistricting provides comprehensive features and functionality for plan management, visualization, editing and community collaboration.

It can be used to develop district boundaries that are substantially equal in population based on race, existing communities, voting age population, and other data variables collected by the U.S. Census Bureau and local jurisdictions. It provides users with access to the 2010 and 2020 (when available) Census data required for redistricting, and allows for plan creation and editing, plan management, district reporting, district integrity checks, plan publishing and sharing, and other useful tools to support the redistricting process.  


Esri Redistricting provides a high value, cost effective alternative for many organizations.  The following are key differentiators and tangible benefits of using this product:

  • Reduces implementation time and cost. Redistricting capabilities and data is made accessible through a web browser which eliminates the need for software installation, or a high‐end desktop or laptop computer.
