From the Urban Institute:
The number of uninsured people would rise from 28.9 million to 58.7 million in 2019, an increase of 29.8 million people (103 percent). The share of non-elderly people without insurance would increase from 11 percent to 21 percent, a higher rate of uninsurance than before the ACA because of the disruption to the non-group insurance market.
Of the 29.8 million newly uninsured, 22.5 million people would become uninsured as a result of eliminating the premium tax credits, the Medicaid expansion, and the individual mandate. The additional 7.3 million people would become uninsured because of the near collapse of the non-group insurance market.
And that’s just for starters. You can read the entire report, “Implications of a Partial Repeal of the ACA Through Reconciliation,” here. And thanks, Leftover, for the link.
