Approximately what fraction of all stars in the Milky Way are estimated to be red dwarfs?

Answer

As much as three-quarters

Red dwarfs are not just the smallest stars; they are overwhelmingly the most numerous stars in the Milky Way galaxy. Current estimations suggest that these cool, faint bodies constitute a substantial majority of the galaxy's stellar census, potentially making up as much as three-quarters of all stars. This numerical dominance means that despite their faintness individually, they collectively represent the largest reservoir of stellar mass and the most common type of stellar object throughout the galaxy's structure.
