  • Of the 10 Local Health Areas (LHAs) with the statistically significant and high perinatal complication ratios in 1998 (number of births in parentheses), the five highest ratios were:

    018Golden1.85(47)
    027Cariboo-Chilcotin1.36(167)
    046Sunshine Coast1.36(102)

    038Richmond0.91(489)

    All of these LHAs also had statistically significant low ratios in 1993-1997.

  • There were 28 LHAs with statistically significant and high perinatal complication ratios in 1993-1997. The six LHAs with the highest ratios, which were statistically significant (number of births in parentheses), were:
