  The kinematics of jets in active galactic nuclei (QSOs, BL Lacs, Radio
Galaxies and Empty Field objects) on parsec scales is being studied with Very
Long Baseline Array observations at 15 GHz of a sample of more than 170 radio
sources. More than 1000 images have been taken since 1994. Here we present an
overview of the results of our study, including the proper motions of
components in the jets, and their relationship with other source properties.
