NUMBER OF UNINSURED: 835,000 state residents are uninsured, or about 14 percent.
WHERE THE STATE STANDS: Missouri received an initial planning grant but has not implemented a health insurance exchange because of opposition to it by some Republican state senators.
WHAT HAPPENS NOW: Regardless of the Supreme Court ruling, Missouri residents will vote in November on a ballot measure asking whether Democratic Gov. Jay Nixon’s administration should be barred from implementing an insurance exchange without specific authority in state law. Nixon has said he will not order the creation of an insurance exchange.
