A critical component to equitable access to data is the ability to find and trust the information you seek. While D3 maintains an open data portal with a wide breadth of downloadable data, we also often use open data resources from other reliable organizations. Sharing resources is a great way to avoid duplicating data efforts!

Each of these resources provides an abundance of data about our city, region, and state.
