Mejillones

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 166 students registered for the PAES.

Aggregate of all the comuna's schools (RBD → comuna). Pass/withdrawal and attendance are from the 2025 school year. SIMCE is not published as open data (managed by the Quality Agency, by request only); the available quality proxy is passing, dropout and attendance. The PAES result appears in the social section.

2024 Census: people who consider themselves as belonging to an indigenous people (small counts are suppressed for confidentiality at the source and not shown). Communities: CONADI national registry as of March 2024 — Araucanía and Los Lagos not refreshed in that update, the count is a floor. Land grants: 2022 registry.

International immigrants per the 2024 Census (people born outside Chile living in the comuna). Nationwide they are 1,608,650 people, 8.8% of the population.

Encampments: MINVU National Registry 2024 (irregular settlements and the families living in them). Quantitative deficit: homes missing per the 2024 Census (doubling-up + unrecoverable overcrowding). Permits: new homes authorized by the Works Directorate in 2024 (INE) — measures future construction, not stock. Subsidies: MINVU by application comuna — DS49 accrues beneficiaries by resolution year; DS01 and DS52 accrue payments by application cohort (national totals in the source file differ ~1–6% from the comuna sum; the comuna series is published).

Fiscal or economic treatments that apply only to this comuna or its zone, not the rest of Chile. The chip color shows who it reaches: municipality, community, residents, companies or workers.

Road infrastructure of the MOP and concession holders, not the municipality: it measures how much highway crosses the territory, not municipal management. Only comunas with roads of this category are counted.

No air monitoring station (SINCA) in the comuna.

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.

Species of flora, fauna and funga documented in the baselines of the projects evaluated by SEIA in the comuna — what their environmental studies recorded in the territory. Conservation status (RCE/IUCN) and Chilean endemism are flagged.

CR critically endangered · EN endangered · VU vulnerable · NT near threatened (Species Classification Regulation / IUCN). ★ endemic to Chile. Extracted from SEIA studies by kingdom; presence reflects what baselines characterized, not a census.

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. 160 projects totaling US$ 29.324 million, approved between 1993 and 2026. 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.

Points in the comuna where SENAPRED identifies winter-rain risk (channel overflows, flooding, collector collapse, landslides, mudflows, snow), with risk level and the agency responsible for the fix.

Modeled climatology (CMIP6 downscaling ~5 km): present ≈ 1980-2010, projection ≈ 2035-2065 middle scenario. Not recent weather observation.

Police cases (reports + arrests) recorded by Carabineros and PDI. Not victimization (ENUSC measures the real figure, higher due to underreporting). The rate uses INE 2024 population. Source: CEAD, Ministry of Public Security.

Crashes georeferenced by CONASET (urban + highway) during 2024. The only per-comuna source; covers ~70% of the country's deaths (non-geolocatable ones are excluded), so it slightly underestimates the total. Pedestrian collision is the leading cause of pedestrian death.
