The evolutionary process of large, powerful radio quasars and radio galaxies is not well-understood. Pre-existing evolutionary models using simulated catalogs of the radio sky have been compared to observational data in the past, but they were limited by comparatively small real samples. Today, new and larger radio surveys allow more extensive tests that will yield more insight into the nature of these radio sources. We worked with the new observational catalogs from the WENSS, NVSS, and FIRST surveys to determine selection criteria to produce the best sample for such tests. Input parameters were varied in the model code to produce different simulated versions of the radio sky. We compared the observational sample to these "mock catalogs" in order to find the model Universe that best describes the true evolutionary path of radio galaxies.
