Abstract:
|
In 2005, approximately 66% of all deaths in the United States were attributed to five selected causes. This percentage was stable in 2003, 2004 and 2005. Age-adjusted death rates (AADR) by the five leading causes were previously calculated for 2000-2004 and mapped for 805 health service areas (HSAs) across the United States to display geographic distribution. To further explore the geographic patterns of these selected causes, as well as indentify statistically significant hot/cold spots in the distribution pattern, we used ArcGIS 9.3 to apply clustering analysis and a hot/cold spot detection procedure to U.S. national mortality data for 2003-2005. Results from analyses for each of the five leading causes of death are presented and discussed. The methodology of spatial data analysis is also discussed.
