This chapter offers a quantitative perspective through the collection and analysis of the available data from many sources. It includes other European countries in comparison and analysis, mainly Belgium, Italy, France, Netherlands and Portugal, as well as the EU in the cases of homicides, drugs, bribery, money laundering, participation in organised criminal groups and human trafficking and smuggling. Given the gap that academic literature shows in the study of the Spanish case, we have mainly focused on Spain and we have observed many of the main phenomena such as homicides, drugs, bribery, money laundering, participation in organised criminal groups and human trafficking and smuggling.
