What Biobío is specialised in

2024 · SII

Of the 672 activities the tax register files firms under, Biobío employs more people in 114 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.

Revealed comparative advantage (Balassa, 1965) and the space of activities (Hidalgo, Klinger, Barabási and Hausmann, 2007), computed on formal employment because that is what a Chilean commune has. Built from the 500-worker activities and the communes above 1,000 formal workers; the floors are on /datos with everything else.

The land and who works it

Agricultural census · INE · 2020/2021

89.2%

69.8%

of the crop land is irrigated

Pasturehover a tile for its count; click a group to open itFive families of land use, grouped by PuroChile from the fourteen categories the census publishes. The fifteenth tile is not a category: it is the censused surface less the fourteen.

The agricultural census measured 801,965 hectares of holdings in Biobío in the 2020/2021 agricultural year, and this is how it divided them.

Fourteen of the fifteen tiles are categories the census publishes. The fifteenth is not: it is the censused surface less the other fourteen, and what it holds is scrub, barren ground, roads and buildings. Across Chile it is half of everything, because most of the censused surface is Patagonian scrub and northern desert inside very large holdings.

Irrigation is asked of eleven of the uses and not of forest, native woodland, natural pasture or untilled ground — so the 69.8% above is a share of the 93,456 hectares the question applies to, not of the whole.

The census counts holdings by comuna and by region only, and one holding can have land in several comunas — so there is no count for this level and PuroChile does not make one by adding.

The ten programmes they enrolled in most

BiobíoChile

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

BiobíoChile

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 Biobío'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 Biobío 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.

BiobíoChileshare of the valid vote

Congress is compared by list, not by candidate: the candidates change at every district line, and the list — the pact — is the same across the country.

Región del Biobío renewed its senators in 2021, not in 2025, so Biobío has no Senate result in this election.
