For comparison - authoritative(?) data for ONE YEAR:

CDC: Causes for Deaths 2004
Number of deaths for leading causes of death
Heart disease: 652,486
Cancer: 553,888
Stroke (cerebrovascular diseases): 150,074
Chronic lower respiratory diseases: 121,987
Accidents (unintentional injuries): 112,012
Diabetes: 73,138
Alzheimer's disease: 65,965
Influenza/Pneumonia: 59,664
Nephritis, nephrotic syndrome, and nephrosis: 42,480
Septicemia: 33,373

More recent information suggests significant changes: e.g. a massive increase from resistant infections, which would likely fall in the "Septicemia" category.
