Wayuu communities are not uniformly distributed within these territories, as their population is concentrated primarily in the outskirts of such settlements as Nazareth and Jala'ala, on the plains of Wopu'muin and Uribia, and within the municipalities of Maicao and Manaure, where population densities are some of the highest in the peninsula. This irregular distribution is intimately related to seasonal changes in weather – during the dry season, a significant proportion of the population crosses the border into Venezuela to work in the city of Maracaibo and its nearby settlements; once the rainy season begins, these Wayuu tend to return to their homes on the Colombian side.
