Sourcing principles
Where the numbers come from
Every site in the network follows the same rules, so a figure on any of them can be checked.
-
Public data only
Every dataset comes from a public source: a government portal, an open API, a registry, a filing. Nothing is scraped from behind a login or a paywall.
-
Every source attributed
Every number traces back to a named source with a link, shown on the site that uses it.
-
Licences respected
A dataset's licence is checked and recorded before it is used. If the licence does not allow it, we do not use the data.
-
Charts you can read without seeing them
Every chart ships with a plain-language summary and a data table, not just an image.
Who is behind it
One person, one way of building
Public data is everywhere and almost none of it is usable. It is published as quarterly PDFs, unindexed lists and once-a-year press releases, so a normal question takes real work to answer.
Simba Systems is built and run by one person. Every site is made the same way, on the same stack, because one pipeline that fetches, checks and publishes data reliably is worth more than ten sites that each half-work.
