Forward-backward correlation in pp collisions is studied in an approach that emphasizes the partonic scattering angles and circumvents the intractable problem related to the transverse momenta that are low. Assuming the back-to-back scattering of partons to be the origin of hadronic correlation, the properties of forward-backward multiplicity covariance can be derived essentially independent of details of hadronization. The range of correlation in pseudo-rapidity emerges from the study without any dynamical input, thus dispelling the notion that correlation length has any fundamental significance. An attempt is made to relate the results to the two-component structure seen in autocorrelation.
