The DANCe survey provides photometric and astrometric (position and proper motion) measurements for approximately 2 million unique sources in a region encompassing ∼80deg² centered on the Pleiades cluster. We aim at deriving a complete census of the Pleiades and measure the mass and luminosity functions of the cluster. Using the probabilistic selection method previously described, we identified high probability members in the DANCe (i≥14mag) and Tycho-2 (V≲12mag) catalogues and studied the properties of the cluster over the corresponding luminosity range. We find a total of 2109 high-probability members, of which 812 are new, making it the most extensive and complete census of the cluster to date. The luminosity and mass functions of the cluster are computed from the most massive members down to ∼0.025M_☉. The size, sensitivity, and quality of the sample result in the most precise luminosity and mass functions observed to date for a cluster. Our census supersedes previous studies of the Pleiades cluster populations, in terms of both sensitivity and accuracy.
