Last week, the Urban Institute released a report entitled “Taking Stock: Gains in Health Insurance Coverage under the ACA as of March 2015.” The report looks at the rates of the uninsured from the beginning of 2013 (the year before the marketplace opened) through March 2015. This report breaks down these numbers by income, age, race/ethnicity and gender. It also looks at the difference between uninsured rates in states that did expand Medicaid with those that did not. The report can be accessed by clicking here.
