The crime rate in Switzerland in 2018, the last full year on record, is down or at least downward in nature. There were a total of 432,754 violations that were registered formally to the police and the registered on record by the police. Not all crimes are reported, however, and of those, not all are recorded onto the record by police so the total isn't exactly accurate. But, for the record, violations are down a total of 1.4 percent which is good.
Whether the crime is really going down is difficult to determine but we can be fairly sure it is not going up. The crime that goes most unreported is those that are sexual in nature. Thefts are, on the other hand, sometimes faked for insurance money. So, as far as we know, the crime rate is down. That is a good thing.
