The state field captures which U.S. state a Project is located in, using the standard two-letter abbreviation such as TX, CA, or NY. It is required, and together with county it forms the broad jurisdictional context that cultural resource agencies and the Smithsonian trinomial system rely on. Keeping it to a strict two-character code keeps state values consistent across every project, which makes it reliable for filtering and reporting — Relic indexes projects by state so you can quickly pull up all the work in a given state. For finer location detail, the state works alongside location, latitude, longitude, and the UTM coordinate fields.
