In 2015 it was counties in the Upper Peninsula of Michigan that had the highest amount of traffic accidents and deaths, per capita, from traffic accidents, according to the Michigan of State of Police. Luce County had the highest number of traffic injuries per 10,000 residents at 17.15 (40 total) and Baraga County had the highest number of deaths from traffic crashes per 10,000 residents at 1.17 (1 total). Of these injuries and deaths several were directly related to alcohol, a trend that occurred throughout the state. However, when looking beyond the per capita numbers, we see that it was in Southeastern Michigan where the highest number of traffic related injuries and deaths occurred, both where alcohol was and was not a factor, throughout the state. These high numbers can be, at least in part, attributed to the denser population in that region of the state.
In Wayne County in 2015 there were 191 traffic fatalities, 59, or 31 percent, of which were related to alcohol. Additionally in Wayne County, there were 15,713 total traffic crash related injuries in 2015. Of those injuries, 836, or 5 percent, were related to alcohol being involved in the crash. In Oakland County, of the 67 total traffic fatalities, 18 were related to alcohol (27%) and of the 10,406 traffic injuries 608 (6 %) were related to alcohol. In Macomb County, there were 17 fatal accidents related to alcohol out of 59 total fatal traffic accidents (28%) in 2015. In addition, there were 389 alcohol related traffic injuries in Macomb County; this accounted for 5 percent of the total number of traffic crash related injuries.
Of the fatal traffic accidents throughout Michigan in 2015 there were four counties where alcohol was a factor in 100 percent of the traffic fatalities. These counties were: Mackinac, Baraga, Gogebic (all in the Upper Peninsula) and Mecosta. All three of the Upper Peninsula counties had one traffic fatality, all of which were attributed to alcohol being involved in the crash. Mecosta, in Mid-Michigan in the lower Peninsula, had four fatal traffic accidents in 2015, all of which alcohol played a factor in.
Conversely, there were 31 counties in the state where there were no alcohol related traffic fatalities. However, 28 of those 31 counties had zero total traffic related fatalities. Majority of these counties were located in Northern Michigan. Traffic accident injuries related to alcohol though occurred in every county in 2015, according to the Michigan State Police.
