The most densely populated districts lie in Northern and Southern Lima, where the suburbs of the city begin (Spanish: Cono Norte and Cono Sur, respectively) and they are mostly composed of Andean immigrants who arrived during the mid- and late- 20th century looking for a better life and economic opportunity, or as refugees of the country's internal conflict with the Shining Path during the late 1980s and early 1990s. In the case of Cono Norte (now called Lima Norte), shopping malls such as Megaplaza and Royal Plaza were built in the Independencia district, on the border with the Los Olivos District (the most residential neighborhood in the northern part). Most inhabitants are middle or lower middle class.
