For the years 2000 to 2008 we did a trend analysis relating the information on known cases of murdered aboriginal women to homicide rates for all women in Canada. We found that between 2000 and 2008, there was a very similar trend in terms of the homicide trends in Canada.
Essentially, it follows the same trend line over this decade. However, when we're looking at previous decades, what we have identified is that we have very little information, because there is no available information on ethnic identity. But if we were to look at it in terms of inferring what the previous trend might have been, we could probably say that we have underestimated the number of known cases of homicide, back to 1974, by approximately 600 cases.
