The number of police deaths by province is listed at theIraq Index, and it runs the gamut. Wasit Province has half a million people south of Baghdad and only 19 police casualties. Basra has 2.6 million people and 63 police killed. Baghdad, meanwhile, has 715 police officers killed. One could presume that police deaths would be fairly well tracked, and at least have some (but not perfect) correlation with the level of violence overall.

I wuld not assume that police deaths was correlated with the overall death rate. It would depend in part on how much the police put themselves in the line of fire. In Baghdad it may be that both the Iraqi government and the American military put more pressure on the police to help maintain security, while with less suchg pressure in other provinces, the police intervene less and get killed less.
