Interestingly enough that 1.6ish pc makes up 20% of their ethnic population. I guess there about 1000 halal shops in Beijing and super old numbers from 2010 put the Beijing Muslim populations at somewhere a little under 260000. Indeed a pretty small enclave for such a large city. Curiously, despite the relative small size of that enclave I really did notice their presence. Though I guess anything non Han Chinese-related has a tendency to really stick out in Beijing.
