We use accurate absolute UCAC4 proper motions, V-band photoelectric and CCD photometry including our own and compiled data, WISE W1-band mid-IR photometry, as well as extensive compiled radial-velocity and [Fe/H] data for 403 Galactic field RR Lyrae type variables to determine the kinematical parameters of the Galactic RR Lyrae population and constrain the zero-points of the V-, W1-, and Ks-band period-metallicity-luminosity relations for RR Lyraes via statistical parallax.
