Construction
Construction: the most cyclical sector in the register and the one that moves between communes fastest, because a large project appears in a territory's payroll and leaves it within a few years.
Maps exactly onto CIIU Rev. 4 section F.
Territorial distribution
343/346 communesShaded by how much of each commune's own formal payroll this sector is — not by headcount, which would draw the same map of where people live for every sector.
Counted at the firm's registered address, not the workplace. SII assigns a company's whole payroll to the commune of its tax domicile, so a head office in Santiago carries the shifts worked everywhere else. Read this as where the sector files, and the count below as where its workers live.
Communes with at least 200 workers in the sector, so a village with one firm does not top the list.
What the branch is made of
8 divisions · 12 activitiesA section of twenty-one parts says what this page is called. The register files firms two levels below it, and those parts are not one economy: construcción de edificios and construcción de proyectos de servicio público share a letter and little else. Each division has a page of its own.
- Construcción de edificios 316,810
- Construcción de otras obras de ingeniería civil 166,626
- Terminación y acabado de edificios 146,508
- Instalaciones eléctricas, de gasfitería y otras instalaciones para obras de construcción 132,545
- Construcción de carreteras y líneas de ferrocarril 103,916
The list stops where 5 divisions have accounted for 80% of the branch's employment. The other 3 are together 19.5% of it and are drawn above, each as its own tile: every division of the register.

"Workers" is SII's count at the firm's registered address; "living here" is Casen's count of employees of this branch who live in the region. They are different measurements of different things and the columns are read side by side, not subtracted. A dash is a cell with fewer than 30 sampled workers.
