A national study released Friday by Health Families USA reveals that far more people lack health insurance in Connecticut than previously believed. The report revealed that 758,000 people in the state, most of them from working families, went without insurance at some point in 2007 or 2008. That’s more than twice the number most policymakers and pundits had been using. Some 531,000 of the total lacked insurance for at least six months. And that was before the recession hit.

In response to the report, activists renewed the call to pass the “Sustinet” proposal that would cut health-care costs and widen the pool of people available to join a state insurance plan.
