The declining middle class in one and many attributes ∗
نویسنده
چکیده
A new multivariate approach is introduced to identify the middle class of a society and to measure its possible decline. The middle class is a properly defined central region in attribute space that contains a fixed portion of the population. The decline of the middle class is measured by comparing volumes of the middle class. The use of different notions of central regions is discussed in one and several dimensions. An empirical application is given to German data on income and wealth.
