The column represents a demographic percentage (proportion of population with income under $25K) at entity grain. These are intensive levels—each row's percentage describes a property of that entity's population composition. Summing percentages across different entities is meaningless (you cannot add "10.49% + 11.21%" to get a combined demographic measure); averaging is the natural aggregation. The dtype is object (stored as percentage strings), but the semantic content is clearly a bounded proportion between 0-100%, which is an intensive additive measure. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
