Read together, Economy + Health + Housing + Climate + Mobility + Homicide form one scoped view of Nice. Economic output and the modelled apartment market rent frame productive strength against housing cost pressure; they do not, by themselves, measure household affordability. The national health benchmark and current local climate describe different geographic levels, so they can contextualise exposure but cannot establish a Nice-local health effect. Apartment market rent and public-transport stop density can be read together as cost-and-reach context, not as a neighbourhood affordability or transport-access relationship.
