Population trend
How it has changedSource: Official INE series 2002–2026 (2017 base).
See the full trajectory to 2050 →INE projects comuna population only through 2035; the 2050 values are an own estimate by the monitor, anchored to the official INE 2050 national total (21,626,079 inhab, 32.1% aged 60+). Not an official comuna figure.
| Indicator | Value | Source |
|---|---|---|
| Homes with public water supply (2017 Census) | 89,93 % | CENSO 2017 2017 |
| School disengagement (leaves the system) | 0,9 % | MINEDUC 2023 |

| Indigenous peoples | 5,15 % | 2024 Census 2024 |
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 17 students registered for the PAES — far too few: this comuna’s average is unreliable.

A monthly administrative snapshot of the Social Household Registry (self-registration to access benefits), as of abril 2026. The "bracket 40" is the socioeconomic rating of the most vulnerable 40%. It is a registry, not a survey: it complements CASEN (biennial) with fresh data, but well-off comunas under-register. Source: ADIS, Ministry of Social Development and Family.
School educationSource: MINEDUC Open Data 2025
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.
Municipal healthcare (primary care)Source: SINIM · MINSAL / FONASA
REM-26 section A (DEIS/MINSAL): comprehensive family visits, summed across the comuna's facilities. The last year is partial while DEIS consolidates monthly reports.
Indigenous peoplesSource: 2024 Census (INE) · CONADI via IDE SMA
| People | People | % of total |

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.
Community organizationSource: RPJSFL Civil Registry (Law 20.500/19.418) · as of Jun 2026
All the comuna's active non-profit legal entities (Law 20.500 / 19.418), classified by organization name. It portrays the civil fabric: not just neighborhood councils, also committees, sports clubs, cultural and elderly groups, foundations and fire brigades.

The dial (frequency) of every FM, AM and community radio with a studio in the comuna (SUBTEL, active sound broadcasting concessions). National networks appear in their headquarters' comuna, not necessarily where they broadcast. When SUBTEL records no brand name, its holder (the concession holder).
Foreign-born populationSource: 2024 Census · INE
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.
Housing and housing deficitSource: MINVU (Encampment Registry + 2024 Census deficit + subsidies) · INE
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).

Environment and air qualitySource: MMA · SINCA + PPDA + RETC
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.
Biodiversity and protected areasSource: SNASPE · SEIA baselines
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.

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. 1 project totaling US$ 11 million, approved in 2021. 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.
Basic utilitiesSource: SISS · CNE · MINEDUC
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.

Green areasSource: SINIM · SUBDERE (2025)
Municipally maintained green area per inhabitant (SINIM). The National Urban Development Council recommends a minimum of 10 m²/inhab (WHO, ~9). Self-reported by municipalities, with quality varying across comunas.

Forest firesSource: CONAF · Occurrence and damage statistics (2023-2024)
Occurrence and area affected by wildfires (CONAF). The 5-season cumulative gives a fairer picture than a single year: fire is episodic and big catastrophes concentrate in few seasons. The area is comuna-wide, not just urban.
Winter riskSource: SENAPRED · winter critical points 2026 (via FAU U. de Chile)
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.
Water scarcitySource: DGA · MOP (scarcity-zone decrees)
DGA water-scarcity zone decrees (by comuna, province or region; basin decrees are not counted here, so chronicity is a floor). The decree enables extraordinary water redistribution measures. At the megadrought's peak (2021) 286 comunas were under decree; today 26.
Climate and climate changeSource: ARClim · MMA + CR2/UC (CMIP6 modeling)

Road crashesSource: CONASET · Data Observatory (2024)
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.
