Usage

regionalatlas — a CLI for the Regionalatlas Deutschland (Statistische Ämter des Bundes und der Länder). No API key needed.

regionalatlas [global options] <command> [command options]

Global options

Option Description
--base-url <url> ArcGIS data host base URL (default https://www.gis-idmz.nrw.de)
--catalog-url <url> indicator catalogue URL (default the statistikportal.de services.json)
--timeout <ms> time limit per request in ms, whole response included (0 = no timeout; at most 2147483647)
--user-agent <ua> User-Agent header value
--max-retries <n> retries for transient 429/503 responses (0..10)
--max-response-bytes <n> cap the response body size in bytes (0 = unlimited; default 100 MiB)
--compact print JSON on a single line (for piping to jq)
-V, --version / -h, --help version / help

--base-url and --catalog-url accept only http:/https: URLs.

Commands

themes — list the subject areas

regionalatlas themes → [{ title, indicatorCount }, …] (the 21 Themenbereiche).

indicators — list indicators

Option Description
--theme <substr> filter by theme title (case-insensitive substring)
--year <yyyy> only indicators offering this year
--search <substr> filter over code + short + long title (case-insensitive)

regionalatlas indicators → [{ code, table, theme, titleShort, titleLong, years }, …], where years is a compact range (e.g. 2000–2024). titleLong is the catalogue’s long title, which --search also matches (it contains the theme name).

query <indicator-code> — fetch data rows

Option Description
--level <level> geo level: land | regierungsbezirk | kreis | gemeinde (default land)
--year <yyyy> reporting year (default: the newest year in the catalogue, which may not be loaded yet — see below)
--region <name\|ags> keep only rows matching a name substring or an AGS
--fields <a,b,c> keep only these value fields (comma-separated); names are checked against the indicator’s columns

The positional <indicator-code> accepts the code form (AI002-1-5) or the table form (ai002_1_5), case-insensitively. Output is [{ ags, name, typ, level, year, values }, …], one row per region.

--level accepts these aliases: land/laender/bundesland (=1), regierungsbezirk/rb (=2), kreis/kreise/landkreis (=3), gemeinde/gemeinden (=5).

Every level covers all of Germany, filling in with the next coarser unit where the finer one does not exist — so ags length varies within a level. regierungsbezirk returns 38 rows: the 29 actual Regierungsbezirke plus the 9 Bundesländer that have none. kreis (400) and gemeinde (~11 000) carry Berlin and Hamburg at 2 digits, and gemeinde carries 104 kreisfreie Städte at their 5-digit Kreis key. Each level is a non-overlapping partition, so summing or mapping one is safe; counting its rows as “the Regierungsbezirke of Germany” is not. --region and --fields are applied client-side (they never enter the upstream request), but a --fields name is validated against the indicator’s value columns first — indicators lists them with their titles and units.

An empty result prints [], exits 0 and explains itself on stderr. The catalogue can list a newest year the data host has not loaded yet: on 2026-09-15 AI013-1 listed 2026, and query AI013-1 --level kreis returned [], while --year 2025 returned all 400 Kreise. When the year was defaulted, the note names the previous catalogue year to try.

Examples

regionalatlas themes --compact | jq '.[].title'
regionalatlas indicators --search bevölkerung
regionalatlas indicators --theme Wahlen --year 2021
regionalatlas query AI002-1-5 --level land --year 2020                 # 16 Bundesländer
regionalatlas query AI002-1-5 --level kreis                            # ~400 Kreise, latest year
regionalatlas query AI002-1-5 --level land --region Bayern --compact
regionalatlas query AI002-1-5 --level land --fields ai0201 --compact | jq '.[] | {name, values}'

Exit codes

Code Meaning
0 success (help/version included); an empty result also exits 0, with a Note: on stderr — from query and from indicators alike
1 API/logical error (the ArcGIS error envelope), or a catch-all
2 usage / validation error (bad flags, unknown command, unknown indicator, unknown --level, a --year outside the indicator’s range, an unknown --fields column, a non-http(s) or malformed --base-url/--catalog-url, redirecting base URL)
4 HTTP 404
6 network / transport failure (DNS, connection, timeout, response size-cap)
