Open Data Policy + Practice

Building Open Data Policies

Interested in working on an open data policy in your community or exploring how other cities are incorporating open data principles?

Open Data Policy Hub

The Open Data Policy Hub is a “one-stop shop” for drafting, crafting, and enacting open data policy. We created the Open Data Policy Hub as an easy-to-use, accessible platform for anyone looking to begin building an open data policy on their own — replacing content that had been spread out across five different websites.

Open Data Policy Step-by-Step

Public policy is an essential tool in helping governments make cultural shifts toward transparency and openness in the spirit of collaboration. As a cornerstone of open government, open data is one of the best tools data-driven cities can use to begin connecting with and collaborating with their residents.

We’ve developed this guide to help cities pass open data policies on their own. Passing an open data policy should be the first step in creating a sustainable, thriving open data program.

Open Data Policy Guidelines

The Sunlight Foundation created this living set of open data guidelines to inform discussions on what data should be made pubic, how to make data pubic, and how to implement policy.

Open Data Policy Collection

Our Collection includes policies from 107 local and 12 state governments — 60 of which received assistance from or used the resources of Sunlight’s Open Cities team.

View a collection of current municipal and state policies in the United States analyzed against our Open Data Policy Guidelines. See actual legislation text compared to the guideline it successfully addresses.

Open Data Policy Generator

We’ve created an open data policy generator to help local governments write their own open data policies. Simply fill out the form, and we’ll send a sample policy that can be customized to city needs.

Open Data Policies Map

Want to know where all the open data policies are in the United States? There’s a map (and a list) for that. This site also includes links to full policy language, which we encourage new cities to incorporate into their own open data policies.

Open Contracting Data Policy Guidelines

Sunlight and the Open Contracting Partnership (OCP) developed a set of guidelines to help cities make public contracting data easily accessible and useful to all. Sharing contracting information openly can help governments build public trust, improve the effectiveness of their own agencies, and empower the private sector to make wiser investments.

Publishing Open Data

U.S. City Open Data Census

The U.S. City Open Data Census is a benchmarking tool that gives city staff and residents an understanding of what datasets are available in their city, and how their city compares to others across the country when it comes to open government data.


As part of our exploration of best practices for open data generally, we also examine the potential impact of opening specific kinds of information. Our “Deep Dives” take the magnifying glass to priority data for different communities, highlighting the current state of this data across the country, crafting recommendations for how its disclosure could be improved, and sharing demonstrations of just what happens when this information is made available and accessible.

Asset disclosure

Lobbying might evoke images of power brokers in Washington, D.C., but lobbyists are also influential at the local level of policy. Learn More

Campaign Finance

Campaign finance disclosure is an essential public accountability mechanism. Providing public access to this kind of information about the flow of money in politics empowers oversight and accountability in the government decision-making process. Learn More


Zoning impacts the most physical elements of our communities and daily lives — from the location of your local supermarket (and what you can purchase there) to the size and height of your home. Learn More


Crime impacts every community. The information generated from incidents of crime fuels a wide variety of news stories and apps that keep people updated on important public safety issues. Learn More
