Oldenburg has low violent crime rates compared to other bigger cities. You will see people walking or biking alone at night , especially around city centres, uni areas. Buses are reliable and safe , even late. Lots of students travel around the town during day.

It is a very calm and quiet city. Besides the sadly normal catcalls nothing ever happened to me and I feel totally safe walking in the city at night,also because the city center is very small and therefore easy to overview

It's pretty safe. Most of the crimes happen in the city or between people who know each other. There have recently been a few violent crimes during the night which all happened in the city center. We have lots of stuff on our terrace, which is accessible from the outside and nothings ever been stolen.

Oldenburg is a really cute, safe and lovely student city and the safest place I ever lived at (I’m kinda commute from Bremen to Oldenburg and used to stay longer in multiple states of the US ), very recommended !
