Ok, looking at the chart I am starting to wonder if this holds- Does Nigeria have less crime than Sweden? I kind of doubt it. I wonder if their crime rate stats are inaccurate. Countries don't always keep accurate records of crimes... Hmmm...
Here is how the determined "crime":
Mean standardized crime rates were computed from the 10 crimes for which the United Nations Office on Drugs and Crime (UNODC) [14] had reliable statistics: homicide (N = 67 countries), robbery (N = 51), rape (N = 48), kidnapping (N = 46), assault (N = 48), theft (N = 47), drug crime (N = 47), auto theft (N = 28), burglary (N = 43), and human trafficking (N = 39). These data were compiled by the UNODC from national government sources, including police and court records, national statistics ministries, and other national government bodies. For each individual crime, the annual data from 2003–2008 were averaged to form a single 5-year measure, except for homicide data, which were taken from the latest available single year (range 2004–2010).
