Estimated to be the costliest natural disaster in U.S. history, Hurricane Harvey left many people with a difficult decision: should I leave my home or wait out the storm? 

With numerous warnings from local and federal agencies, thousands chose to heed hurricane advisories and evacuate their homes. 

Three main questions about movement arise when thinking about evacuations:

1. Where did people leave?
2. Where did people go?
3. And who decided to stay?

Utilizing Teralytics data aggregated from billions of signals obtained daily from cell towers and other unique sources, Esri created a map that attempts to answer these three questions.
