Deep inelastic scattering cross section measurements previously published by the H1 and ZEUS collaborations are combined. The procedure takes into account the systematic error correlations in a coherent way, leading to a significantly reduced overall cross section uncertainty. The combined H1 and ZEUS measurements of the inclusive neutral and charged current cross sections are used to perform a common NLO QCD fit. The consistent treatment of systematic uncertainties in the joint data set ensures that the resulting set of parton density functions (PDFs) have a much reduced experimental uncertainty compared to the previous PDF extractions performed separately by the H1 and ZEUS collaborations.
