State Health Facts is a KFF project that provides free, up-to-date, and easy-to-use health data for all 50 states, the District of Columbia, and the United States. It offers data on specific types of health insurance coverage, including employer-sponsored, Medicaid, Medicare, as well as people who are uninsured by demographic characteristics, including age, race/ethnicity, work status, gender, and income. There are also data on health insurance status for a state's population overall and broken down by age, gender, and income.
This slideshow explains key elements of the Medicare program, which now provides health coverage to 55 million people — including 46 million people age 65 and older and another 9 million younger adults with permanent disabilities.
Ever since the Supreme Court ruled in June 2012 that states could effectively choose whether or not to accept the Affordable Care Act’s expansion of Medicaid eligibility, that choice has been one of the most prominent and often one of the most contentious issues for states. In this report, we provide new projections of the impact of Medicaid expansion on health coverage, Medicaid enrollment, and costs in states that have not expanded Medicaid.
Continuing an effort to explore Affordable Care Act (ACA) implementation in the states, the Kaiser Family Foundation and the Blue Shield of California Foundation examined ACA implementation in California (CA) at a Sacramento, Calif. briefing and panel discussion on May 28. A state official, experts and advocates discussed issues and challenges related to implementation of the law, and the practical impact of providing coverage to roughly 4.5 million Californians who have coverage via the state marketplace or the Medi-Cal expansion.
This brief explains the key provisions of the Senate’s Better Care Reconciliation Act (BCRA), and their effects on adults ages 50-64. The brief also discusses how changes to Medicaid could affect older, low-income adults, and how an increase in the number of uninsured older adults could have implications for the Medicare program in the future.
This brief provides national and state-by-state estimates of the reductions in federal spending under the Better Care Reconciliation Act for the period 2020-2029 and for 2029 in order to see the full effect of policy changes over a ten-year period.
Congressional debate around the Affordable Care Act (ACA) has recently included a proposal to repeal the ACA, including the provision allowing states to extend Medicaid to childless adults up to 138% FPL and providing enhanced federal funds for the Medicaid expansion. This brief provides estimates of changes in federal Medicaid funds and Medicaid coverage for adults covered through the ACA expansion if the expansion is eliminated starting in 2020. A repeal of the Medicaid expansion would have significant coverage and financing implications for the 31 states and the District of Columbia that have implemented the expansion.
This slideshow examines the poor uninsured adults in the coverage gap in states that have not expanded Medicaid under the Affordable Care Act (ACA) and shows who is affected by the gap.
New in-depth profiles of 12 people with HIV highlight how the Affordable Care Act’s coverage expansions impacted their access to coverage and care.
