Many basic government services do not reach all residents of these districts due to their difficult geography.
Once important settlements created during the era of colonization, they nowadays do not offer much space for agriculture.
Districts located outside the colonized area have very low populations that are entirely composed of Native Amazonian tribes.
Districts in the Chala (coastal area) tend to be mid-sized except in low-density areas such as the Sechura Desert and part of the Southern coast, but all of them feature large populations due to emigration from other regions of the country that turned the Peruvian coast into the country's main economic powerhouse.
Districts with a population of more than 10,000 inhabitants should ideally be subdivided, particularly if they are also large in area, as is the case in part of the Amazon rainforest.
