So, this is a combination of demographics and some potentially-misleading statistics.
First, the statistics. As Mark Twain liked to say, “There are three kinds of lies: lies, damned lies and statistics.” Statistics are almost always not telling you the whole story, and at times misrepresenting things entirely. It doesn’t help that most of the people who use statistics are not really statisticians. (Myself included, I am not going to claim expertise in the field, but I know enough to know how little I know and how badly it is often misused and misunderstood.)
In Nunavut, the territory that is darkest on the map above, there are actually only 37,000 people (according to wikipedia). The map shows the murder rate per 100,000. Thus, if there is a single murder in Nunavut, it is going to count three times as much as a murder in a more populated state/province/territory. This can cause the statistics to be skewed a bit, as you are dealing with a sample size below your benchmark size, and extrapolating based on small sample sizes can result in exaggerated stats. As a (rather poor, admittedly) example, if you had a room full of 100 people and 1 person was murdered, the murder rate on the map would be 1000 people per 100,000, but in reality there was only one murder. So it could be that the way in which the statistics are presented on the map makes it seem worse than it is.
As an added problem, the map actually doesn’t convey the information it is trying to convey in a complete way. A rate is how often something happens over time. The map above tells us the rate of murders per 100,000 population, but it doesn’t tell us what time interval it is looking at. A year? A decade? A month? This could have a big impact on the statistics, as again, if you are using a small sample size (or in this case potentially looking at a short period of time) outlying results can skew the data. It could be that there was a particularly bad year that is being represented. Without any actual indication about the time frame looked at, we can’t say one way or the other. (Also, it means that this map fails to convey the information it purports to represent, and that is one of my pet peeves. It is like saying “My speed was 10 km″. 10 km per what? 10 km/hour? 10 km/minute? 10km/second? 10 km/year? There is a big difference between all of those. Using incomplete units makes me sad.)
All the statistics aside, there are also some real demographic and cultural issues that make Nunavut suffer from more violent crime. Nunavut does have a problem, I am not trying to deny that, but I also want to warn people that maps and statistics can be misleading.
To understand the issues in Nunavut you need to look at the way Canada has treated its aboriginal peoples in general, as well as the Inuit specifically. Canada has a sordid history that is only now beginning to be recognized by the government when it comes to their treatment of the aboriginal peoples of Canada. Canada for a long time considered what the called “The Indian Problem” (or “The Eskimo Problem” in reference to the Inuit specifically) to be a burden on their nation. The “Indian Problem” as they saw it was the fact that there were aboriginal peoples at all, and that the Canadian government was obligated to tend to their needs by virtue of the fact that they lived within the borders of the relatively recently formed nation of Canada. The fact that aboriginal peoples had very different customs, beliefs and cultural practices made plenty of European-descended Canadians uncomfortable, and they saw them as alien. The solution, in their minds, was to convert every aboriginal person into a “Canadian” by forcing them to adopt the dominant white european christian culture. By doing this, they hoped that there would be no “Indians” anymore asking for what some in the government saw as special treatment and they could treat them just like any other Canadian.
In order to bring about this conversion, Canada forced aboriginal children to attend residential schools. These schools separated children from their parents, their families, their tribes and their culture. The children were expected to dress like “Canadians”, learn about “Canadian” history, culture, beliefs and ideas, and once they graduated they would be “proper Canadians”. This idea was flawed both in concept and in execution. In concept, this has been equated to cultural genocide, as Canada sought to erase aboriginal cultural identities, affiliations, languages and beliefs. In execution, the government couldn’t even run things they way they thought was right. Because of the cost of the schools, the government didn’t want to pay to run them, so they turned them over to private organizations, mostly religious organizations. The staff the churches and other organizations hired were not trained teachers, and were more concerned with the “spiritual salvation” of the children than their education or even their general wellbeing. The organizations were constantly trying to cut costs, and they had very little oversight. The results were brutal. Students were beaten if they misbehaved, which included speaking their native languages, or engaging in any sort of behavior that was seen as “Indian”. Their names were replaced with “Canadian” names. They didn’t even receive the education they were promised, as lots of residential schools essentially used the children as forced labor to produce goods that the school would sell to boost their budgets. Not that the children ever saw the benefits of this. They were constantly malnourished and unhealthy, as they were given the cheapest food possible to keep costs low, or even only fed irregularly. Meanwhile, the teachers were well-fed on good food. Then there was also the fact that abuse was rampant. Physical, emotional, and sexual abuse was very common as the schools had basically no oversight. Mortality rates at the schools were between 30% and 60%, and as a teacher, the fact that the schools even had a mortality rate is incredibly upsetting.
Of course, the students who survived eventually left the schools. And this is where we start to see the effects on violent crime. Survivors of the residential school system frequently suffered from severe PTSD, depression, anxiety or other conditions. Suicide rates among survivors were high. A sad result of this was the fact that with their treatment in the schools and the lack of support outside of them, many of the survivors ended up perpetuating the cycle of abuse. Studies have shown that children who survived corporal punishment and abuse are more likely to engage in that sort of behavior as adults. The last residential school was closed in 1996, and as a result, there are multiple generations of first nations people who suffer from the physical, emotional and cultural scars of the residential school system. This can be seen almost as a wound on the spirit or culture of the entire people, as even if an aboriginal person has not experienced the effects of the residential schools themselves, they almost certainly felt the aftereffects on their lives and their communities. In such an environment, sometimes there are people who resort to violence to solve their problems, not knowing any other way to address them. The lack of health care, especially mental health care, among aboriginal communities certainly exacerbate the problem.
There are more issues that affect the violent crime rates as well. The Inuit people were traditionally nomadic, migrating along the coasts, following seasonal game. The Canadian government didn’t like this, as it made administering the territory difficult. Canadians forcibly relocated several villages to a more permanent location, but did not bother to ensure that the location was suitable for the Inuit people to live there. The Canadian government eventually established a number of permanent administrative centers in the region, and the Inuit eventually migrated to live in these permanent habitations, with the access to education, health care and economic opportunities drawing many, though there were still some who were forcibly relocated. Within two generations the self-sufficient Inuit people had almost completely changed into a sedentary people, however, their lack of what were considered marketable skills in the Canadian economy resulted in rampant poverty. Increasing numbers of Inuit ended up relying on the government to survive.
Another problem in Nunavut is alcohol. Nunavut is the only province or territory in Canada that still has prohibition, and as history has shown us, prohibition does nothing to prevent alcohol use other than making it more clandestine. An estimated 95% of crimes are alcohol related, and it is believed that it contributes to the violent crime rate. They’ve recently moved towards legalization, but I don’t know when the map was made.
So essentially, you have a people who have been forcibly or at the very least strong-armed into changing their entire lifestyle from a self-sufficient one to one in which poverty is widespread, alcohol abuse is high, and their entire culture is suffering from the wounds and abuse of the residential school system. All of these are related to increases in violent crime.
