Population types of cataclysmic variables in the solar neighbourhood

► Galactic orbital parameters of cataclysmic variables (CVs) are calculated. ► About 6% of cataclysmic variables are thick disc stars. ► There is no halo CVs in the Solar vicinity. ► About 60% of the thick disc CVs have orbital periods shorter than 2.6 h. ► A kinematical age of 13 Gyr is obtained for the most probable thick disc CVs.
