Where these numbers come from
Rhode Island medians come from editorial and are refreshed weekly. The Cranston figures index those state medians to the local market, so they track the same feed rather than going stale. Insurance and the state income tax rate are editorial. Treat everything here as a planning estimate, not a quote.
