We present VLBA observations and a statistical analysis of 5 GHz VLBIpolarimetry data from 177 sources in the Caltech-Jodrell Bank flat-spectrum(CJF) survey. The CJF survey, a complete, flux-density-limited sample of 293extragalactic radio sources, gives us the unique opportunity to compare a broadrange of source properties for quasars, galaxies and BL Lacertae objects. Wefocus primarily on jet properties, specifically the correlation between the jetaxis angle and the polarization angle in the core and jet. A strong correlationis found for the electric vector polarization angle in the cores of quasars tobe perpendicular to the jet axis. Contrary to previous claims, no correlationis found between the jet polarization angle and the jet axis in either quasarsor BL Lac objects. With this large, homogeneous sample we are also able toinvestigate cosmological issues and AGN evolution.Comment: Accepted to the Astrophysical Journal: 37 pages, 14 figure
