- Known limits
- Nationality is a legal status (Swiss citizens, including naturalised persons, and foreign nationals); it says nothing about origin. The permanent resident population includes foreign nationals with a residence permit of at least 12 months and, since 2010, persons in the asylum process with at least 12 months of residence (STATPOP definition). Counts are on 31 December, while the labour force survey (bfs-sake-labour-status) gives yearly averages: compare the two only with that in mind (see the cross-checks on /work-and-support). The old-age ratio uses 65 as a fixed age; the AHV reference age for women was 64 until the AHV 21 reform raises it from 2025.

Transformations
- PxWeb POST (json-stat2): Switzerland (8100), permanent resident population (Bevölkerungstyp 1), sex total (-99999), every nationality category (total, Schweiz, Ausland) and every single year of age 0 … "100 Jahre und mehr", every year. Script: scripts/fetch/bfs-statpop-age-structure.ts
- Single years summed into age_0_14, age_15_64 and age_65_plus (these three add up to the total), plus age_18_64 (denominator of the invalidity rate in bsv-iv-pensions) and age_20_64 (denominator of the old-age ratio). The fetcher fails unless the single years add up to the published total and Swiss + foreign = total in every year and group.
- old_age_ratio = age_65_plus ÷ age_20_64 × 100, two decimals: residents aged 65 and over per 100 residents aged 20 to 64 (the BFS definition of the "Altersquotient"). A ratio of two published counts, computed by Votara.
