Trying to make any logical links in the chart. For example wealth of the country, culture, etc. Seems almost random. I wonder how much is due to crime reporting. For example in the UK, and I am sure many other countries, people report burglaries not so much in the hope of the criminal being caught but so that they can claim on their insurance. Had a friend in Moss Side, Manchester who was burgled. The police did not even go inside the property, just put a card through the door with the crime number on it so they could claim.
