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 Urban Institute defined the middle class as adults with size-adjusted household incomes of between $30,000 and $100,000 for families of three. The Pew Research Center defines the middle-income category as including adults with family-of-three equivalent incomes between two-thirds and double the national median. This brings the range from $37,666 to $113,000 according to current levels.
