For more on the methods for adjusting Medicare expenditures for regional differences in prices, please read our technical report.

Selected primary care access and quality measures
Data include measures of primary care utilization, quality of care for diabetes, mammography, leg amputation and preventable hospitalizations. More information can be found in Regional and Racial Variation in Primary Care and the Quality of Care among Medicare Beneficiaries (2010).
Selected hospital and physician capacity measures
*2011 rates for physician workforce only. 2012 rates for hospital resources only.
Note: some HSAs show large population shifts between the 2006 estimates and the 2010 estimates (used for 2011 and 2012 data). These shifts are attributed to several factors. Some may represent actual population changes. Others may reflect changes in methodology. The 2006 estimates were extrapolated from the 2000 Census, which used ZIP Code Tabulation Areas (ZCTAs) as their basis. The 2010 Census counts are based on Census tracts, which may change the geographic relationships. Users should be aware of this when comparing 2006 to 2011 or 2012 data. These changes have little to no impact at the HRR level.Back to top
