Data credits
Navigator Data is compiled from public government publications, licensed datasets, and open data, then normalized and checked by Navigator.
Some of the open datasets we incorporate are published under licenses that require public attribution. This page carries those credits. Other providers are integrated under agreements that do not call for public attribution; everywhere else in the product, our aggregated dataset is referred to simply as Navigator Data.
