The PAES year is that of the admission process: the test is sat in November of the previous year. The average covers only those who registered to apply to university —not every secondary-school graduate— and groups them by the comuna of the school they graduated from, not by where the student lives. Here it rests on 461 students registered for the PAES.

Air quality observed at MMA's SINCA stations within the comuna (2020); when there are several, the worst is shown. The scale compares the annual average with the WHO 2021 guideline (PM2.5 = 5 · PM10 = 15 µg/m³, international health reference) and the Chilean annual primary standard (PM2.5 = 20 · PM10 = 50 µg/m³): green within the WHO guideline, amber between guideline and standard, red above the national standard. "Days above standard" use the 24-h daily standard (PM2.5 = 50 · PM10 = 150 µg/m³). RETC emissions = declared point sources (industry/energy), excludes diffuse sources like residential firewood.

Area = hectares of wetland within the comuna boundary (apportioned using the DPA table of each record). For wetlands shared between comunas, "portion / total" is shown. "Urban" = urban wetland (HUR code). Official source migrated to the SBAP (Law 21,600).

Large projects approved by SEIASource: SEIA · approved projects

Projects with an environmental permit (RCA) approved by SEIA and declared investment above US$ 10 million, located in the comuna according to the case file and grouped by sector. Every sector with at least one project is listed: this is not a ranking or a selection. 15 projects totaling US$ 175 million, approved between 1998 and 2025. When a project spans several comunas, its investment is split among them.

Approved is not the same as built or operating: the RCA authorises the project, but some were never carried out and others have since closed.

Source: projects with an RCA approved by SEIA (investment declared by the developer, split among the comunas the project spans). Under each sector are its two largest projects by investment. It is the best public proxy for large industrial sites; SERNAGEOMIN’s registry of active mining operations (by mineral and type of operation) is a layer not yet incorporated.

Almost no comuna has its own utility: it is served by a major regional concession holder. Water = urban operational territory (SISS; rural goes via APR); electric = concession distributor per the tariff decree (CNE); higher education = university, IP and CFT campuses (MINEDUC/SIES), with the nearest comuna when there are none.
