Higher income and uninsured: common or rare?

Massachusetts plans to penalize those who do not have health insurance, targeting higher-income people. Are higher-income Americans a small or substantial share of the uninsured? The U.S. Census Bureau reports that one in three Americans without health insurance lived in a household with income greater than $50,000 in 2005. Many of these higher-income uninsured people do not fit the profile of free-riders who have the money but are unwilling to buy coverage. A majority have lower incomes but live with others; only together are they higher income. For others, higher income or lack of insurance is transient.
