Ñuñoa, Chile

This commune in northeast Santiago has seen a 47% population surge over 15 years, now home to 241,467 residents. While Ñuñoa boasts a high quality of life, with an 87.66 regional index and 0.860 Human Development score, the rapid growth has caused friction with long-time residents. Developers snatching up older homes to build multi-unit complexes have faced backlash, as the area struggles to maintain its character as a peaceful, predominantly residential zone. With an average income of $44,409 and just 4.3% living below the poverty line, Ñuñoa caters to the medium and upper-middle class seeking a convenient, amenity-rich lifestyle in the capital.
