Millions of Americans who buy their own health insurance have been informed that their policies will no longer be offered starting next year because they do not meet the higher standards of the Affordable Care Act. The actual number of people receiving the notices is unclear, in part because officials in 20 states say they do not have the information or are not tracking it.

Some states are tracking the policy notifications through their insurance departments or health care exchanges. In other states, the largest private insurers are releasing the number of discontinuation notices they have issued.

This list shows that at least 4 million Americans have received the notices so far. It reflects reporting by AP staffers in each state and the District of Columbia, as of Thursday, and does not include policy cancelations in the small-business insurance market.
