Residents of the Panama City, Panama boroughs of Clayton and Albrook, as well said by other contributors, are middle/high income level. Housing is good quality, and it has more green areas than other neighborhoods. Nice and safe.
Close to the Panama Canal visitor´s center, few minutes from the Albrook Mall, and the 2 bridges to go to the "interior" (country side of Panamá) makes Clayton an attractive area. Still, traffic is heavy, and not all facilities are within the neighborhood boundaries. Clayton is located at 30 minutes from Gamboa resort.
As a special note, I´ll mention that it is not called "Panama Canal Zone" anymore...it's simply "Panamá Canal." And is not "Fort Clayton".... it's "Clayton."
