The column stores percentage values (0.00% to 1.55%) representing the proportion of population with less than high school education at each entity. These are intensive demographic attributes—absolute levels that describe a characteristic at a point, not extensive quantities that accumulate. Summing "1.29% + 1.38%" across two counties produces a meaningless result; the natural aggregation is mean (weighted by population if available). The values are stored as formatted strings (dtype=object) but represent percentage levels, confirming intensive_additive classification. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
