  We present a progress report on the kinematical analysis of the entire SPY
(ESO SN Ia Progenitor surveY) sample of about one thousand white dwarfs and hot
subdwarfs. In a previous study (Pauli et al. 2003, 2006) 398 DA white dwarfs
have been analysed already. Here we extend the study to 634 DA white dwarfs. We
discuss kinematic criteria for a distinction of thin disk, thick disk and halo
populations. This is the largest homogeneous sample of white dwarfs for which
accurate 3D space motions have been determined. They have been derived from
radial velocities, spectroscopic distances and proper motions from catalogues.
Galactic orbits and further kinematic parameters were computed. Our kinematic
criteria for assigning population membership are deduced from a sample of F and
G stars taken from the literature for which chemical criteria can be used to
distinguish between thin disk, thick disk and halo members. The kinematic
population classification scheme is based on the position in the $VU$-velocity
diagram, the position in the eccentricity-JZ diagram and the Galactic orbit. We
combine this with age estimates and find 12 halo and 37 thick disk members
amongst our DA white dwarfs. We were unable to determine the population
membership of only nine of them. The remaining members of the sample of 632
stars belong to the thin disk population.
