it can be infered since it never says that there are any other clans that lived there and it specifically says the PEOPLE of Uzushiogakure, were noted for there long lives. also the fact the villiage is named after the uzumaki clan indicates that the only clan that lived there was uzumaki. there may have been non clan members who lived there but that could mean in the form of marriage into the clan or what not. or like how not everyone in a village belongs to a clan ie sakura doesn't belong to a clan. when showing Uzushiogakure they only showed uzumaki members we know this because everyone shown was wearing the cloths that uzumaki members wore
