22. For purposes of the population census, any place or site of Uruguayan territory in which many people -- relatives or not -- live permanently in houses or dwellings of any kind, such as ranches, shacks, camps, etc. and is used for one or more classes of work, jobs, or labors, either of agriculture, livestock, commercial, industrial, artisan, fishing industry etc., will be known by the generic name "populated nucleus".

23. It is not necessary that a place or site has streets or plazas nor its own authorities or churches. It can have a specific name by which it is known presently, in order to differentiate it from similar or nearby places or sites.

24. It is not important that the houses or dwellings are separated from each other as generally occurs in establishments in the country or in quarry areas (canteras); the most important thing is that people who live in these houses constitute a group of people united or linked by common interests for example their job or occupation. In summary, these people are considered neighbors and they recognize the existence of boundaries that separate and differentiate the place or site where they have their houses from other places or neighbors.

25. With this criteria, not only are cities, towns, villages, and colonies considered "populated nucleuses", but also equally ranches, farms, camps, etc. including also isolated dwellings (for example, tents) when they are independent of the farms or they are separated from a principal house since in other manners they would not be included, by omission or forgetting, in the population census.
