Reference Groups:

  • Children: Very young children 0-4 years of age are compared with children 15-17 years.
  • Elderly: Individuals 65 years of age and older are compared with adults 18-44 years.
  • Women: Women are compared with men.
  • Low-income residents: Individuals from communities with the lowest median household incomes (<$25,000) are compared with residents from communities with median household incomes of $45,000 and above.
  • Rural residents: Individuals from rural areas are compared with urban dwellers.

Notes:
"+" indicates hospitalization rates are higher for the priority population compared with the reference group (significant at p<0.05).
"-" indicates hospitalization rates are lower for the priority population compared with the reference group (significant at p<0.05).
"Increased" indicates hospitalization rates increased over time (significant at p<0.05).
"Decreased" indicates hospitalization rates decreased over time (significant at p<0.05).
"No difference" indicates hospitalization rates are comparable between the priority population and the reference group.
