Nominally i would agree but how reliable is data? My thoughts are cities like San Pedro which are not tourist sites have far less crime because it doesn't attract criminals. That's not why I choose to live here but it is a big advantage.
From my experience of San Pedro de Macoris and the surrounding towns, the crime rate is as high or higher than other places in the DR. It probably doesn't make the news because firstly there are few gringos and secondly people don't report crimes, because they don't trust the police. Personally I feel safer in Cabarete than when I stay in Consuelo, just outside Sand Pedro.
