Accordingly, X (the number of deaths if everyone in this age group had insur- ance) was 40,548 divided by 1.05, or 38,617. The number of deaths resulting from uninsurance was the actual number of deaths (40,548) minus the number of deaths that would have resulted without any uninsured (38,617), or 1,930. 1
approximately 18,000 deaths resulted from uninsurance in 2000 (table 1).
Applying the IOM meth- odology to more recent Census estimates of the number of uninsured
number of uninsured yields an estimate that 137,000 adults age 25–64 died because of uninsurance from 2000 through 2006, including 22,000 people in 2006 (table 2). This represents an average of one death every 24 minutes.

TABle 1. IOM estimates of the number of deaths resulting from uninsurance among adults age 25–64: 2000
T he IOM analysis may have under- estimated the number of deaths resulting from uninsurance. The underlying longitudinal studies on which IOM relied did not specify the impact of insurance coverage on mortality by 10-year age groups. Rather, they doc- umented the relationship between insurance and mortality across the sum t o t a l o f a l l s u r v e y e d a g e g r o u p s . 2 T h IOM’s methodology implicitly assumed that insurance reduces mortality by the identical percentage for each 10-year age band, which the underlying research did not show. More grounded in the research would be an application of differen- tial mortality estimates to all adults age 25–64, as was done for those longitudinal e

Excess deaths due to uninsurance
Notes: Numbers are rounded to the nearest 1,000. otals may not add correctly because of rounding. This table s estimate for uninsured excess deaths in 2000 is slightly lower than the total published by the IOM because this table reflects the Census Bureau s downward adjustment of the number of uninsured from 2000 through 2005. In addition, the estimates in this table are based on estimates of the civilian population, and the IOM numbers included active-duty military; this table s estimates are based on weights derived from the 2000 Census, rather than the 1990 Census; and the table s estimates incorporate the NCHS s final death rate estimates for 2000, rather than the estimates for 1999 used by IOM.
Notes: Numbers are rounded to the nearest 1,000. otals may not add correctly because of rounding. This table displays the results of calculations that modify the IOM methodology by estimating excess deaths for 25–64-year-olds as a whole rather than for each 10-year age cohort among 25–64-year-olds.
