Number of civilian casualties (non-combatant deaths) per 100,000 people in 2010: Iraq, Ingushetia, Afghanistan, Kabardino-Balkaria, Dagestan, and Russia’s North Caucasus as a whole
So, Ingushetia (part of Russia’s North Caucasus Federal District) nears Iraq in number of civilian casualties: 12.6 compared to 12.9, respectively, and it actually has more non-combatant deaths than Afghanistan (8.5).
Caucasus Knot (Kavkaz Usel) article, used by Russian opposition leader Vladimir Milov as the source for Russia’s North Caucasus data, says that in real numbers, Dagestan leads 2010 civilian casualties with 78, followed by 40 in Ingushetia, 31 in Kabardino-Balkaria, 20 in North Ossetia, and 3 in Chechnya and Stavropol Territory, for a total of 180 civilian casualties in Russia’s North Caucasus in 2010. (My understanding is that numbers in the graph are a result of comparing the number of civilian deaths to the number of people living in the region.)
Thus, somewhat paradoxically (although not really surprisingly), Chechnya does not have that many civilian casualties anymore, because the violence from Chechnya has spilled to the neighboring Dagestan and Ingushetia.
