In less-developed countries, in addition to land use and density requirements, a requirement that a large majority of the population, typically 75%, is not engaged in agriculture and/or fishing is sometimes used.
U slabije razvijenim zemljama, osim zahtjeva o uporabi zemljišta i gustoći stanovništva, ponekad se rabi zahtjev da se velika većina stanovništva, obično 75 %, ne bavi poljoprivredom i/ili ribarstvom.
