-#  Why restrict active variables to person-counts?
-#  CA chi-square distance has a clean compositional interpretation only when
-#  all active columns measure the same type of unit. When counts of persons,
-#  dwellings, farms, and vehicles share a row, the row total is meaningless
-#  and chi-square distance becomes a weighted average of incompatible profiles.
-#  Restricting active columns to person-counts ensures that chi-square distance
-#  directly compares "what fraction of the population has attribute X?" across
-#  municipalities, independently of population size.
