The northeastern zone of Santiago de Chile, known as “sector oriente”, refers to the name given to the communes to the east of the Santiago commune, where the majority of the population with the highest income in Chile live.

In 2002 it had 45.3% of its population in the socioeconomic group "ABC1" equivalent to the classes previously mentioned, and 31% in the group "C2" (middle). The communes of the northeast sector lead the Human Development Index (HDI) not only at the city level, but also at the national level, being among the 6 highest of the 346 communes in the country. In the same way, the sector as a whole contains the highest average cost in the price of housing and offices per square meter in the country, due to the high price of urban land in the area.

Carried out in a 2015 study, the communes are the best in quality of urban life index, and with the highest availability of green areas in the city, as long as other services. Also, due to its pre-Andean orientation, it is called the «upper neighborhood of Santiago».
