One of Ohio’s largest key cities is also one of its most dangerous cities. To begin with, it has a population of over 400,000. This makes it extremely difficult to control. In terms of violent crimes, it ranks 1st all over the state. It has also been included on the list of the most dangerous cities not just in Ohio, but around the country. The entire city though is not dangerous. The reason why it always makes the list is because of some really bad neighborhoods, including Chestnut Place and Scovill Avenue. Other parts of downtown Cleveland are actually safe.
