Research and health policy organizations are excellent sources of data and information. Some organizations are strictly centrist in their political orientation, while others are clearly advocating health policies aligned with a political agenda. Commercial sites are sources of information and education as well, though the amount of information offered for free versus requiring payment varies widely.
These are health policy organizations that are either centrist and relatively neutral, or more oriented along political lines: Liberal, Conservative, or Libertarian. Some organizations self-identify their orientation, while others have been categorized by me and do not necessarily represent their own view of themselves. Regardless of political orientation, these sites all have useful information and resources. Selection of these sites as useful links does not represent any political orientation by me, but simply their utility.
These commercial websites and publications contain a variety of useful information about health insurance and managed health care. Some data and information is free, some requires registration, some requires subscription, and some requires payment.
