Lower mean age-adjusted rate
What this means: Connecticut sits in the bottom third by mean age-adjusted rate (46.2/100K; corpus #50 of 51). Landing below the national figure puts the state in reasonably good aggregate standing, though it's still worth checking the trend below to confirm the gap is holding rather than narrowing.
Lower-rate third on mean age-adjusted leading causes (2017). Heart disease still leads locally. Rates are CDC WONDER age-adjusted; see /methodology#corpus-placement.
