[1][2][3][4][5][6][7][8] In American society, the middle class may be divided into two or three sub-groups.
Common occupation fields are semi-professionals, such as lower-level managers, small business owners and skilled craftsmen.
These individuals commonly have some college education or perhaps a Bachelor's degree and earn a comfortable living.
[9][10] Though not common in sociological models, the middle class may be divided into three sections in vernacular language usage.
Yet some class models, such as those by sociologist Leonard Beeghley, suggest the middle class to be one cohesive socio-economic demographic, including the demographics otherwise referred to as lower, simply middle or upper middle class in one group comprising about 45% of households.
