Idaho is pretty sparsely populated and mainly rural which leads to lower car insurance rates. According to World Atlas, Idaho has the seventh least population density in the country. There are roughly 20 people for every square mile. Wide-open spaces with few people mean fewer cars out on the road and fewer accidents, everything an insurance company loves.
