Political Party Membership

Party membership is public under the Political Parties Act, and the e-Business Register publishes each party's current member list as a CSV export. No authentication, no session cookie.

Use when

• You need how large a party is, or how the parties compare.
• You need to check whether a named person is on a party's public list.
• Not for campaign finance — that is party-funding-data.

Retrieve

Use the module below. It resolves the party, downloads the register's own CSV and counts in code.

const r = await partyMembership("Reformierakond");
show(r.totals);       // { members, suspended, byJoinYear, joinedThisYear, longestServing }

const all = await partyMembershipRanking();   // every registered party, one call
show(all.totals);     // { parties, members, largest }
show(all.rows);       // party, members, sharePct

partyMembershipRanking() downloads all 14 registered parties (~1.8 MB, ~6 s) and ranks them, so a "which party is biggest" question needs no second call and no hand-added subtotals.

What byJoinYear is, and is not

It counts how many of today's members joined in each year. It is not the party's membership in that year: everyone who has since left is absent, so the series slopes downward into the past for reasons that have nothing to do with recruitment. The register holds no leave dates at all. State what the series measures, or say nothing about the trend — this is the caveat the module's note repeats because it is the easiest wrong graph to draw here.

Personal data

The default answer is a count. Personal rows come back only from partyMemberCheck(party, name), i.e. when the question is about a named person, and even then only the birth year — the register publishes the full date and a year is enough to tell two people apart. Never republish a bulk member list when an aggregate answers the question.

Limits

• The register publishes no count, only the list, and one live party's export is a third of a megabyte — so the counting has to happen in code, and plain requests are not enough here: they would put nearly nine thousand people's names in front of you instead of the number you asked for.
• The chooser lists two tables: registrisse kantud (14 live parties) and registrist kustutatud (17 struck off). They are not distinguished by markup, only by the heading between them — counting them together doubles Estonia's parties. politicalParties() returns status per row.
• A struck-off party exports an empty member list. That is the register's answer, not a failed download.
• The export is a snapshot taken at request time; report retrievedAt.
• Historical aggregates live in a Power BI page (https://ariregister.rik.ee/eng/statistics/political_parties) that only renders in a browser.

Verify

The CSV must arrive as text/csv with the register's own header — First name;Last name;Date of birth;Date of starting membership;Suspension of membership in political party, semicolon-delimited, UTF-8 with BOM. The module throws when that header is missing, which is what tells a real empty list from an HTML error page.
