Chile's Electoral Service (Servel) updated the distribution of 155 seats in the Chamber of Deputies based on census data from the National Institute of Statistics (INE). The resolution, published last Thursday, adjusts representatives per district, with limits of 3 to 8 deputies per area.
Every ten years, Servel reviews the territorial allocation of 155 seats across 28 districts based on census population. The board issued the resolution last Thursday, adhering to rules that prevent districts from having fewer than 3 or more than 8 deputies.
In the Metropolitan Region, district 11—covering Las Condes, Lo Barnechea, Vitacura, La Reina, and Peñalolén—increases from 6 to 8 seats. Districts 14 (Calera de Tango, Talagante, Buín, and San Bernardo, among others), 9 (Recoleta, Huechuraba, and Cerro Navia, among others), and 12 (La Florida, Puente Alto, and others) also rise to 8. District 13 (San Miguel, El Bosque, and Pedro Aguirre Cerda, among others) goes from 5 to 6.
Outside the capital, reductions occur: Atacama's district 4 (Copiapó, Diego de Almagro, and Caldera, among others) drops from 5 to 3, as does Los Ríos' district 24 (Valdivia, Río Bueno, and La Unión, among others). Regions including O’Higgins, Maule, Ñuble, Los Lagos, and La Araucanía see similar losses.
Following publication in the Official Gazette, a period allows challenges before the Electoral Qualifications Tribunal (Tricel). Such redistributions often spark political debate due to their effects on districts with strong partisan leanings.
