  1. Notes:
  2. 1. “Injury” defined as any diagnosis in the range ICD9:800–999.
  3. 2. Injuries occurring during the observation period 1987-Jan-01 to 2010-Dec-31.
  4. 3. Person-years is the sum of annual population counts during the observation period.
  5. 4. Observed number of injuries.
  6. 5. Expected number, indirectly standardized, based on age, gender and HSDA-specific rates in total population of BC.
  7. 6. Crude Rate per 10,000 person-years.
  8. 7. Standardized Relative Risk (compared to the total population of BC) = Observed/Expected.
