What is the shelf life of a condom? I know every package of condoms has an expiration date on them. But, I need to figure out when a specific package of condoms was manufactured by looking at the expiration date.
Middle class. The middle class is a class of people in the middle of a social hierarchy. In Weberian socio-economic terms, the middle class is the broad group of people in contemporary society who fall socio-economically between the working class and upper class. The common measures of what constitutes middle class vary significantly among cultures.
The upper middle class is a sociological concept referring to the social group constituted by higher status members of the middle class. This is in contrast to the term lower middle class, which is used for the group at the opposite end of the middle class stratum, and to the broader term middle class. There is considerable debate as to how the upper middle class might be defined.
