Declared assets and income
Every deputy declares their assets and income on taking their seat and whenever something changes. Here it is as they wrote it, one declaration at a time.
How we read this data
The Congress only publishes them as scanned PDFs: we read them automatically and only show the ones that pass every check. If in doubt, the official PDF prevails. Descriptions are shown as written, in Spanish.
We add nothing up: the form asks no value for homes or land, and later declarations only list what changed.
Income is for the year before each declaration and leaves out the Congress salary, which is already public.

The form asks no value for it.
Activities and interests
What each deputy did in the five years before the seat, what gifts they received, who they contribute to, and what activities the Congress authorises them to keep while they sit. As they wrote it.
Where it comes from
The Congress publishes the activities register once the plenary decides whether each activity is compatible with the seat, and rewrites it when it changes. We read it every week.
The deputy files the declaration of economic interests on taking the seat and when something changes. It has no amounts: it says where they worked, not what they earned.
Both are published only as PDFs: we read them automatically and only show what passes every check. If in doubt, the official PDF prevails. Texts are shown as written, in Spanish.
