The column represents percentage values (1.66%, 1.71%, etc.) describing the proportion of entities with income $100K+ at each entity's location/grain. This is an intensive property—a demographic composition level—not an extensive quantity that accumulates. Summing percentages across different geographic entities is meaningless; the natural rollup is mean (weighted by population if available, simple mean otherwise). The values are absolute levels centered away from both 0 and 1, confirming intensive_additive classification. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
