Open government data is important because the more accessible, discoverable, and usable data is the more impact it can have. These impacts include, but are not limited to: cost savings, efficiency, fuel for business, improved civic services, informed policy, performance planning, research and scientific discoveries, transparency and accountability, and increased public participation in the democratic dialogue. Below are just a few examples of people leveraging open data. While we don’t endorse any particular use, we’re always interested in new examples: Submit impact suggestions here.
