The charged particle multiplicity and the differential charged particle density are studied in pp collisions at a centre-of-mass energy of sqrt{s}=7TeV. The measurement is performed for events with at least one charged particle in the kinematic range of p>2 GeV/c, pT>0.2 GeV/c and 2.02GeV/c, pT>0.2GeV/c und 2.0
