The distribution of the masers in the Galaxy, and statistics of their multiwavelength counterparts is consistent with the hypothesis of 6.7GHz maser emission being associated with massive young stellar objects. Using the detection statistics of our survey, we estimate the minimum number of methanol masers in the Galaxy to be 1275. Description: The methanol maser sample comes from the Arecibo Methanol Maser Galactic Plane Survey (AMGPS), which is discussed in detail in Paper I (Pandian et al., Cat. J/ApJ/656/255). The sample has 86 methanol masers, 77 of which have peak flux densities above the completeness limit of 0.27Jy. File Summary:
