method have earned him the title of the "founder of modern empirical sociology". Lazarsfeld made great strides in statistical survey analysis, panel methods, latent structure analysis, and contextual analysis. He is also considered a co-founder of mathematical sociology. Many of his ideas have been so influential as to now be considered self-evident. In the 1970's, Peter Townsend redefined poverty from the previous definition of 'total earnings being too little to obtain the minimum necessities of physical life', to one which also took into account the relative deprivation caused, meaning that not having access to the typical level of lifestyle was also a form of poverty. During the same decade, Pierre Bourdieu, advancing the concept of habitus, argued that class was not defined solely by economic means, but also by the socially acquired taste which one shared with the rest of the class. Beyond economic capital, he also identified cultural, social, scholastic, linguistic, and political capital. These all contributed towards symbolic capital. Richard Sennett in turn found that working-class people were finding themselves in crisis following rising social status, as it conflicted with the values of their background. Structuralism Structuralism is "the belief that phenomena of human life are not intelligible except through their interrelations. These relations constitute a structure, and behind local variations in the surface phenomena there are constant laws of abstract structure". Structuralism in Europe developed in the early 1900s, mainly in France and Russian Empire, in the structural linguistics of Ferdinand de Saussure and the subsequent Prague, Moscow and Copenhagen schools of linguistics. In the late 1950s and early 1960s, when structural linguistics were facing serious challenges from the likes of Noam Chomsky and thus fading in importance, an array of scholars in the humanities borrowed Saussure's concepts for use in their respective fields of study. French anthropologist Claude Lévi-Strauss was arguably the first such scholar, sparking a widespread interest in structuralism. Modernization theory Modernization theory is used to explain the process of modernization within societies. Modernization refers to a model of a progressive transition from a 'pre-modern' or 'traditional' to a 'modern' society. Modernization theory originated from the ideas of German sociologist Max Weber (1864–1920), which provided the basis for the modernization paradigm developed by Harvard sociologist Talcott Parsons (1902–1979). The theory looks at the internal factors of a country while assuming that with assistance, "traditional" countries can be brought to development in the same manner
