How Geographically "Mixed" are Different Callers in Turkey?

"Refugee Caller Diversity" is a measure of how Syrian refugee callers and Turkish native callers are geographically "mixed" with each other regradless whether these two types of callers ever met and connected in reality. It simply calculates the percentage of total number of refugee callers over total number of callers (refugees + natives) recorded at each base station in Turkey. The maps below are interpolated results based on the values of calculated percentages stored at base station points (each feature point symbolizes the location of the relevant base station on map). Below, "Refugee Caller Diversity" was not only mapped at national level, but also was mapped at city-province levels for Istanbul, Ankara, and Izmir, the top three most populous cities/ provinces in Turkey.
