您说得没错，地道英文是不会如此的。immediate area of Grant City 没问题，指的就是 Grant City 从市中心算起紧邻的地区。但是 不可以说 immediate XXX area.some regional data 个人以为想表达的可能是 Grant City 周边的区域，用 suburban 合适。so 是画蛇添足，与前句并无因果关系无需 so.ends up 应该改为 过去时 ended up，说这句话时事情已经发生了。建议改写方式：it ended up that I have more data than just the immediate area of Grant City, I've also included data on its suburban area.
