This is the second in a series of three papers in which we present an end-to-end simulation from the MICE collaboration, the MICE Grand Challenge (MICE-GC) run. The N-body contains about 70 billion dark-matter particles in a (3h 1 Gpc) 3 comoving volume spanning 5 orders of magnitude in dynamical range. In this paper we introduce the halo and galaxy catalogues built upon it, both in a wide (5000 deg 2 ) and deep (z < 1:4) lightcone and in several redshift snapshots. Friend-of-friends halos were resolved down to few 10 11 h 1 M what allowed us to model galaxies down to faint luminosities (absolute magnitudes Mr < 18:9). We used a new hybrid Halo Occupation Distribution and Abundance Matching technique for galaxy assignment. The catalogue includes the Spectral Energy Distributions of all galaxies from which we can model multiband photometric galaxy surveys. We describe a variety of applications for halo and galaxy clustering statistics. We discuss how mass resolution eects can bias the large scale 2-pt clustering amplitude of poorly resolved halos at the . 5% level, and their 3-pt correlation function. We
