We derive the local dark matter density by applying the integrated Jeans equation method from Silverwood et al. to SDSS-SEGUE G-dwarf data processed and presented by Budenbender et al. We use the MULTINEST Bayesian nested sampling software to fit a model for the baryon distribution, dark matter, and tracer stars, including a model for the 'tilt term' that couples the vertical and radial motions, to the data. The α-young population from Budenbender et al. yields the most reliable result of ρ_dm= 0.46^+0.07_–0.08 GeV cm^–3= 0.012^+0.002_–0.002 M_☉ pc^–3. Our analyses yield inconsistent results for the α-young and α-old data, pointing to problems in the tilt term and its modelling, the data itself, the assumption of a flat rotation curve, or the effects of disequilibria.
