The paper treats the validity problem of the nonrelativistic Vlasov-Poisson equation in dimensions. It is shown that the Vlasov-Poisson dynamics can be derived as a combined mean field and point-particle limit of an N-particle Coulomb system of extended charges. This requires a sufficiently fast convergence of the initial empirical distributions. If the electron radius decreases slower than , the corresponding initial configurations are typical. This result entails propagation of molecular chaos for the respective dynamics.
