In 2004, the overall IHS P&S rate was higher than the U.S. rate (3.5
and 2.7 cases per 100,000 population, respectively)
Within IHS, 55 of 60 (92%) P&S cases in 2004 occurred in 3 Areas in
the Southwest [Navajo (34 cases), Phoenix (11 cases), and Albuquerque (10
cases)]; 7 IHS Areas had no P&S cases in 2004
In 2004, the P&S male-female case ratio for IHS overall was 0.9, which
indicates a similar number of cases occurring among men and women

to 2.7 cases per 100,000 population, while overall IHS P&S rates increased
21% from 2.9 to 3.5 cases per 100,000 population; among IHS Areas, the largest
rate increase occurred in the Albuquerque Area (94% increase)
Notes:
IHS rates based on AI/AN living in service counties
U.S. rates based on all races and ethnicities
Exclusions: States with >50% of cases with unknown race excluded
Adjustments: States with ≤50% of cases with unknown race have cases
redistributed; Cases from partial IHS Area service counties are redistributed
