Hi, if you want to have an accurate translation of the question you wrote, in spanish that would be:
"¿Cuál es la ciudad en donde naciste?"
Although, the previous question is grammatically correct, it is not usually used that way. It is most common to simplify the question, as follows:
"¿En qué ciudad naciste?" (If you want to know specifically the city)
"¿Dónde naciste?"
I hope my answer can help you :)
