A company known as ValuePenguin recently did a study of the safest cities in Texas, and found that University Park ranks third on its list of mid-sized cities (20,000 to 50,000 population) in the state.
The study included 210 cities and towns (not Highland Park, however), with big cities generally faring worse than their suburban counterparts. Its criteria included an analysis of FBI crime report data from 2013, including violent crimes and property crimes.
Anyway, UP came in ninth overall in the survey, just behind the Houston suburb of Friendswood and just ahead of Keller. At the top of the list was Murphy, located in Collin County. Dallas was No. 199, and Houston was last. Here is the full report.
