二十世纪末后十年，天津市青少年犯罪情况呈不同以往的新变化：青少年犯罪人口比重逐步走低；女性犯罪构成低微却不可逆地缓增；低龄化被年龄逐步升高取代；外来青少年成为犯罪青少年主体；犯罪的前科“阅历”逐年降低；钱财取向的犯罪目的持续强化增长；团伙犯罪的数量逐步下降，而规模却稳步增长；总体稳定的罪名结构出现了局部变化。 Ten years after the end of the twentieth century, the situation of juvenile delinquency in Tianjin showed a new and different change from the past: the proportion of the juvenile delinquency gradually dropped; the feminization of crime was modest but irreversibly increased; the younger age was gradually replaced by the gradual increase of age; the juvenile delinquents became criminals The number of criminals in gangs decreased gradually while the scale of them increased steadily; and the general structure of guilty charges changed in a partial way.
