What is income-distribution?

A data workflow for Icelandic income statistics from Hagstofan, the national statistics office. It produces average and median income figures by income source, age and gender, plus tax-burden datasets.

Use it to analyse income, employment income, disposable income and taxes across demographic groups from 1990 onward. The workflow writes several analysis-ready CSV files.

It avoids repeatedly querying and cleaning the same official tables. The guidance highlights important details such as values being reported in thousands of Icelandic króna and the difference between mean and median.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00042	$0.00480
Opus 5	$0.00021	$0.00240
Sonnet 5	$0.00008	$0.00096
Haiku 4.5	$0.00004	$0.00048

Security

Grade A, and why

income-distribution scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Income distribution (TEK01001)

Hagstofan income-by-source statistics: mean and median income by income type, age band and gender, 1990–2024. PX-Web table TEK01001 at

https://px.hagstofa.is/pxis/api/v1/is/Samfelag/launogtekjur/3_tekjur/1_tekjur_skattframtol/TEK01001.px

uv run python scripts/income_distribution.py

Writes six tidy CSVs to data/processed/: income_by_source.csv, income_by_source_gender.csv, income_by_age.csv, tax_burden.csv (all TEK01001 cuts) plus total_income_distribution.csv (TEK01006) and employment_income_distribution.csv (TEK01007).

Code cheatsheet — Tekjur og skattar: 0=Heildartekjur, 1=Atvinnutekjur, 2=Fjármagnstekjur, 3=Aðrar tekjur, 4=Skattar, 5=Ráðstöfunartekjur (disposable). Eining: 0=mean, 2=median. Kyn: 0=all. Aldur: 0=all, Y16-64, Y25-54, 5-year bands 16–85+.

Gotchas that bite:

Values are in thousands of ISK, not ISK — 8080 is 8,080,000 kr.
Eining=2 is the median, not a second mean — treating both columns as means silently double-counts.
The PX response is UTF-8 with a BOM — decode utf-8-sig or the first header carries \ufeff.
Income-type rows include taxes (4) and disposable income (5) — never sum across rows to get "total income"; 0 is already the total.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

income-distribution is a skill published in the GitHub repository jokull/icelandic-data (52 stars, last pushed yesterday), licensed MIT. It adds 42 tokens to every session and 480 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
