The column contains percentage values (0.61% to 10.70%) representing demographic proportions—an intensive measure where each value is a standalone proportion for that entity. These are absolute percentage levels, not ratios or growth rates; summing them across entities is meaningless (you cannot add "10% of population A" to "5% of population B"). The appropriate reducer is mean to find average demographic representation. This is intensive_additive: a level measure where averaging, not summing, is the natural aggregation. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
