The Center for American Progress reports [thinkprogress.org][1]
Approximately 17,000 people could die in 2018 who otherwise would have lived if a House Republican health proposal endorsed by the Trump administration becomes law. By 2026, the number of people killed by Trumpcare could grow to approximately 29,000 in that year alone.
Determining the exact number of deaths that could occur each year due to a lack of access to insurance is not an exact science. But ThinkProgress calculated these estimates by examining two sources.
The first is a Congressional Budget Office report released [March 13] that details the impact of the House Republican health bill. It estimates that "in 2018, 14 million more people would be uninsured [thinkprogress.org][1] under the legislation than under current law", and projects this number will rise to "24 million in 2026".
The second source is a study [annals.org] [Abstract] examining the change in Massachusetts mortality rates after the state enacted health reforms similar to the Affordable Care Act. That study, which looked at adults aged 20 to 64, estimated that "for every 830 adults gaining insurance coverage there was one fewer death per year".[2]
