Cleveland Museum of Art · CC0 1.0The figures behind the report
The annexes bring together 42 statistical tables, accompanied by the definitions and the margin of error of each series. They make it possible to reproduce all the report's charts.
They are published in spreadsheet format and in open databases. Each table comes with its source, its reference period and the number of observations on which it rests.
This page presents the main tables and how to use them.

Reading a statistical table
Each table has a header indicating the unit, the period and the source. Values in brackets are provisional. Cells marked with an asterisk rest on fewer than thirty observations and should be interpreted with caution.
The series are expressed in current euros unless otherwise stated. Currency conversions use the rate on the day of sale. Aggregates may differ slightly from the sum of their components because of rounding.

How the annexes are compiled
The annexes are generated automatically from the Observatory's production database, then reviewed by two analysts. Each table is frozen at a precise date, shown in its header, so that two users working at different dates can tell whether they are talking about the same figures.
When a series is revised, a new version of the file is published with an incremented number and a change log. Earlier versions remain accessible: a figure cited in an article or a decision can thus always be found as it was published. This version discipline is one of the guarantees of the reliability of the Observatory's open data.
