What Buin is specialised in
2024 · SIIOf the 672 activities the tax register files firms under, Buin employs more people in 96 of them than Chile does, proportionally. That comparison is Balassa's revealed comparative advantage: this place's share of an activity, over the country's share of it. Above one, the activity is over-represented here.

The register files a firm at its tax address, so an activity can be over-represented here because the work happens here or because the head office does. Both are real facts about a place and they are not the same fact, and nothing in the register tells them apart: the communes where large firms keep their registered office carry activities that are physically elsewhere in Chile.

Women's schooling as share of men's · 100 means parity; below 100, women in the territory completed fewer years than men.

The ten programmes they enrolled in most
Each bar is that programme's share of everyone who continued, here and in the country — not a headcount, so a commune of a few hundred can be read beside a country of 121,050. Programme names as the register writes them: in capitals and without accents, and unmerged, since SIES publishes 1,481 distinct names in a single year and two spellings of one degree stay two rows. Only the capitals are undone here.
By field of study
The ten broad fields of ISCED-F 2013, as SIES classifies each programme, as a share of everyone who continued, here and in the country.
Nineteen cohorts, 2006–2024
left secondary schoolenrolled the following year
Only enrolment the following March counts — someone who works for a year and starts after that is not here, so the rate is a floor under how many ever study, not an estimate of it. Adult secondary education is counted separately and is not in these figures. What the approximation above does not settle is catchment: this is the cohort Buin's schools taught, and where schools draw pupils from next door that is not the same set of children as the ones the territory raised.
Health
See all →The hospital figures come from DEIS's discharge register: one row per completed stay, in any establishment in the country, counted in the commune where the patient lives rather than where the hospital is. It counts stays, not people — someone admitted three times is three of them.
The deaths it records are the ones that happened during a stay. Deaths at home or in the street are in the vital statistics register, which is a different DEIS release and is not in PuroChile — so nothing here is this place's mortality, and every label says «hospitalaria» for that reason.
The two standardised ratios are the ones meant for comparing places: they hold Buin against what its own age and sex structure would produce at the country's rates, with Chile fixed at 100. A commune of older people buries more people than a commune of young families, and that is demography, not health.
In 2024, 7.5% of the country's discharges arrive with every identifying field replaced by an asterisk and cannot be attached to any commune; what is counted here is the 91.4% that carries one.

The figure beside each name is the distance between the two communes: 0 would be identical, and 1.48 is what separates any two communes in the country. Each bar is one of the seven dimensions, and reaches the end when the two differ on it by twice what two communes picked at random do. Location is not part of the computation: 52% of these pairings cross into another region.
