Use these datasets in articles, research, apps, or visualizations - commercial or not. The only requirement is a visible link back to Rentyfic (https://rentyfic.com) as the source. Each file includes a last-updated date; values are commonly-cited general figures, not legal advice, so verify against current statutes for anything high-stakes.
