  "definition": "A method of apportioning data from one geographic boundary to another when the boundaries do not match. For example, if 20% of a county is located in HUC 1 and 80% is located in HUC 2, then 20% of the population for the county would be assigned to HUC 1 and 80% would be assigned to HUC 2. An area-weighting method involves the assumption that values (the number of people, in this example) are evenly distributed across space (in this case the county).
