I want to know the answer to the following question:
What is the association a district-free city or town and its urban hinterland typically grouped into?
All the background I'm provided with is that "Local associations of a special kind are an amalgamation of one or more Landkreise with one or more Kreisfreie Städte to form a replacement of the aforementioned administrative entities at the district level.". Is that enough to answer the question?
Answer: no
