Nguồn dữ liệu và chính sách dữ liệu

The database holds 1115 source records attached to 185 organizations. Individual citations appear at the foot of the page they support; requirement and fee rows link to their own source directly.

Hệ thống phân cấp nguồn

1. Official organization website. Best for current criteria, structure and the organization's own account of itself. Often silent on fees and on how criteria are applied locally.
2. Official membership materials — brochures, FAQs, dues pages.
3. Official application documents. Frequently the only place initiation fees and dues appear in writing.
4. Organization annual reports. Member counts, chapter counts, finances.
5. Government filings — IRS Form 990s, Companies House, SEC. Reliable for legal names, ownership and revenue.
6. Reliable business publications with named authors and dates. The main source for undisclosed fees, and always labelled "reported" rather than "published".
7. Credible interviews where the speaker is named.
8. Other reputable secondary sources. Used with low confidence and never on their own for a material figure.

For every requirement and fee: the source URL, the source title and publisher, the date accessed, the published date where known, the date last verified, and a confidence level. For organizations: the last date the record as a whole was checked. All of it is visible on the page and carried in the JSON and Markdown representations and the API.

Fees and criteria change without announcement. A figure not re-verified within twelve months is marked wherever it appears. Member counts older than twenty-four months are marked. Official websites are checked automatically and a failing link is flagged to the editors. Verification dates are never restamped without an actual check against the source.

Những gì chúng tôi sẽ không trích dẫn

Content generated by AI systems. Aggregators and comparison sites that do not name their own sources. Lead-generation pages. Any page whose commercial relationship with its subject is undisclosed. Anonymous forum claims about fees or acceptance rates.

Nhiếp ảnh

Photographs of real places and organizations carry their creator, source and licence beside them; commercial-use permission, attribution requirements and restrictions are recorded for every file, and the sources are Wikimedia Commons and other collections whose licences permit this use. A photograph is attached to an organization only when it shows that organization — its building, clubhouse or event. Where no such photograph exists the page carries none rather than a stand-in, and no image on the site is generated.

Tin tức

Headlines are collected from the public feeds of named publications, shown with the publisher, and linked to the original. Nothing is republished. Publishers who would rather not be included can write to us and the feed will be removed.

Facts are not owned, and the site does not claim otherwise. What is the publisher's is the selection, organization and arrangement of the database, the taxonomy, the editorial analysis, the scoring methods and the software. Quoting a figure with attribution and its verification date is welcome; systematic extraction and reproduction of the database are prohibited by the terms. The API exists for programmatic questions.
