In this study, we derive the intrinsic density distribution of different stellar populations using the final data release of the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey. A total of 203,197 red giant branch stars are used to sort the stellar disk ($R \\leq 20$ kpc) into sub-populations of metallicity ($\\Delta$[M/H]$= 0.1$ dex), age ($\\Delta \\log(\\frac{\\textrm{age}}{\\textrm{yr}})= 0.1$), and $\\alpha$-element abundances ([$\\alpha$/M]).
