The data sample corresponds to an integrated luminosity of 137.1\\fbinv, collected by the CMS experiment at the LHC. The integrated cross sections of \\PZ~$+\\geq$~1~\\cPqb~jet\\xspace and \\PZ~$+\\geq$~2~\\cPqb~jets\\xspace are reported for the electron, muon, and combined channels with full Run 2 data. The measured integrated cross sections are 6.52 $\\pm$ 0.04 (stat) $\\pm$ 0.40 (syst) $\\pm$ 0.14 (theo) pb for \\PZ~$+\\geq$~1~\\cPqb~jet\\xspace and 0.65 $\\pm$ 0.03 (stat) $\\pm$ 0.07 (syst) $\\pm$ 0.02 (theo) pb for \\PZ~$+\\geq$~2~\\cPqb~jets\\xspace. The differential cross section distributions are measured as a function of various kinematic observables that are useful for precision tests of the perturbative quantum chromodynamics predictions. The ratios of integrated and differential cross sections of \\PZ~$+\\geq$~2~\\cPqb~jets\\xspace and \\PZ~$+\\geq$~1~\\cPqb~jet\\xspace processes are also determined. The value of the integrated cross section ratio measured in the combined channel is 0.100 $\\pm$ 0.005 (stat) $\\pm$ 0.007 (syst) $\\pm$ 0.003 (theo). All of the measurements are compared with predictions from Monte Carlo simulations.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.115490.v1/t1","@type":"Dataset","description":"Differential
