People in the UK now fit into seven social classes, a major survey conducted by the BBC suggests.
It found the three traditional 20th century categories of working, middle and upper class are out of date, fitting only 39% of people.
It found a new model of seven social classes ranging from the elite at the top to a "precariat" at the bottom.
More than 161,000 people took part in the Great British Class Survey, the largest study of class in the UK.
Stuart Miles is the founder and CEO of an online gadget review website who was classified under the technical middle class category.
