Lack of health insurance and type of coverage (Released 09/2011) Early Release of Selected Estimates Based on Data From the 2010 National Health Interview Survey page 3 Figure 1.1. Percentage of persons of all ages without health insurance coverage at the time of interview: United States, 1997–March 2011 0 5 10 15 20 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 Percent 95% confidence interval Jan.-Mar. DATA SOURCE: CDC/NCHS, National Health Interview Survey, 1997–March 2011, Family Core component. In early 2011, the percentage uninsured at the time of interview was 15.3% (95% confidence interval = 14.39%–16.12%), which was lower than, but not significantly different from, the 2010 estimate of 16.0%. The percentage uninsured at the time of interview was lowest in 1999 and 2005 (14.2%) and highest in 2010 (16.0%). NOTES: Data are based on household interviews of a sample of the civilian noninstitutionalized population. • A person was defined as uninsured if he or she did not have any private health insurance, Medicare, Medicaid, Children’s Health Insurance Program (CHIP), state-sponsored or other government-sponsored health plan, or military plan at the time of interview. A person was also defined as uninsured if he or she had only Indian Health Service coverage or had only a private plan that paid for one type of service, such as accidents or dental care. • The data on health insurance status were edited using an automated system based on logic checks and keyword searches. For comparability, the estimates for all years were created using these same procedures. The resulting estimates of persons without health insurance coverage are generally 0.1–0.3 percentage point lower than those based on the editing procedures used for the final data files. Occasionally, due to decisions made for the final data editing and weighting, estimates based on preliminary editing procedures may differ by more than 0.3 percentage point. • The analyses excluded persons with unknown health insurance status (about 1% of respondents each year). • See " Technical Notes " for more details.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
