Modernization theory both attempts to identify the social variables that contribute to social progress and development of societies and seeks to explain the process of social evolution. Modernization theory is subject to criticism originating among socialist and free-market ideologies, world-systems theorists, globalization theorists and dependency theorists among others. Modernization theory stresses not only the process of change but also the responses to that change. It also looks at internal dynamics while referring to social and cultural structures and the adaptation of new technologies.
Modernization theory maintains that traditional societies will develop as they adopt more modern practices. Proponents of modernization theory claim that modern states are wealthier and more powerful and that their citizens are freer to enjoy a higher standard of living. Developments such as new data technology and the need to update traditional methods in transport, communication and production, it is argued, make modernization necessary or at least preferable to the status quo. That view makes critique difficult since it implies that such developments control the limits of human interaction, not vice versa. And yet, seemingly paradoxically, it also implies that human agency controls the speed and severity of modernization. Supposedly, instead of being dominated by tradition, societies undergoing the process of modernization typically arrive at forms of governance dictated by abstract principles. Traditional religious beliefs and cultural traits, according to the theory, usually become less important as modernization takes hold.
Historians link modernization to the processes of urbanization and industrialization and the spread of education. As Kendall (2007) notes, "Urbanization accompanied modernization and the rapid process of industrialization." In sociological critical theory, modernization is linked to an overarching process of rationalisation. When modernization increases within a society, the individual becomes increasingly important, eventually replacing the family or community as the fundamental unit of society.
