Demography of Paris [english Question]

I’m looking for the quartier-level population numbers of Paris.

For example the Quartier Saint-Vincent-de-Paul (OSM) has only numbers from 1999 in Wikipedia.

Where can I find newer data?

Sorry for asking in English & thanks in advance.

Inside the spreadsheet you will see a column “Population en 2015 (princ) P15_POP” for small geographical units in France.
Filter on “GRD_QUART” with your ref:INSEE=7511037 for the Quartier Saint-Vincent-de-Paul.
