Sudbury sits at City Score rank #234 with a standing of 46%, from 7 of 8 open-data pillars (tax, construction, connectivity, indoor air, water, seismic hazard, growth, safety). Missing pillars score at median standing so thin coverage cannot inflate the rank. Dropping 37 places versus 2022 (#197 → #234).
Latest owned placements: indoor radon rank #69 of 327 at 131 Bq/m³ survey mean; residential mill rate rank #25 of 57 (14.57 mill rate). Full tables and method notes live on each study edition; atlas readings for the same slug open from the topic buttons.
