  The parsec-scale radio properties of 232 active galactic nuclei (AGNs), most
of which are blazars, detected by the Large Area Telescope (LAT) on board the
Fermi Gamma-ray Space Telescope have been observed contemporaneously by the
Very Long Baseline Array (VLBA) at 5 GHz. Data from both the first 11 months
(1FGL) and the first 2 years (2FGL) of the Fermi mission were used to
investigate these sources' gamma-ray properties. We use the ratio of the
gamma-ray to radio luminosity as a measure of gamma-ray loudness. We
investigate the relationship of several radio properties to gamma-ray loudness
and to the synchrotron peak frequency. There is a tentative correlation between
gamma-ray loudness and synchrotron peak frequency for BL Lac objects in both
1FGL and 2FGL, and for flat-spectrum radio quasars (FSRQs) in 2FGL. We find
that the apparent opening angle tentatively correlates with gamma-ray loudness
for FSRQs, but only when we use the 2FGL data. We also find that the total VLBA
flux density correlates with the synchrotron peak frequency for BL Lac objects
and FSRQs. The core brightness temperature also correlates with synchrotron
peak frequency, but only for the BL Lac objects. The low-synchrotron peaked
(LSP) BL Lac object sample shows indications of contamination by FSRQs which
happen to have undetectable emission lines. There is evidence that the LSP BL
Lac objects are more strongly beamed than the rest of the BL Lac object
population.
