In the dry Andean area, many districts have fewer than 3,500 inhabitants. In some cases, their populations have decreased in comparison to the days when they were founded. Districts that are located at very high altitudes tend to be scarcely populated. These districts are usually large in area but have little available level land for use. Many basic government services do not reach all residents of these districts due to their difficult geography. Many such districts lack the financial means to govern their whole jurisdictions and often have high emigration rates.
