Understand
What does this number measure?
The year’s capital spending in the administrative account: what the City paid to build, renovate or buy, excluding debt principal repayment and equity stakes. A three-year worksite appears in three years, each for what was paid that year.
Why is only 14% of the amount attached to a named operation?
The administrative account gives the year’s total. Its annexes name only 366 operations, for €219.6 M: 14% of the total. The rest is attached to no named operation. An operation’s amount is what was paid in the year (payment appropriations disbursed, as the annex puts it), not its total cost. 2% of the operations have no address and do not appear on the map.
Where do these numbers come from?
The year’s total: the City’s administrative accounts in the M57 nomenclature (opendata.paris.fr) and, for the fiscal year the City has not yet published there, the DGFiP accounting balance. The named operations: the “Localised investments” annexes of the administrative accounts, read from the PDFs and checked against their printed totals. From 2019 to 2022, the largest projects of the capital programme authorisations dataset (opendata.paris.fr) are added, flagged as such on their page.
