关于“Catchment population”个人认为比较准确的网友解析:
Some place, perhaps an industrial zone or factory district—has access to 233,000 possible workers who could get there within a one-hour journey. The area occupied by everyone who lives within an hour’s travel of the point in question is its primary “catchment area,” so the people in that area are its “catchment population.” Extending the travel time to two hours increases the area to one in which 20 million workers live.
