The avatars of housing in Latin American urban and regional research (1990-2012)

The review of the terms used as keywords in three journals (published in Mexico and Chile) and the Brazilian meetings of regional and urban research are used to analyze the trends in housing research. Their dynamics are interpreted in the light of the general changes identified for urban and regional  research, synthesized by other authors as the emergence of new research topics and agents of urban change (civil society, participation, environment, gender) and the process of globalization (in its facets  of productive restructuration, job flexibility, social exclusion) as a general framework of analysis. It is found that the central themes of research in housing relate primarily to government action in  housing. New concerns, such as citizen participation, the environment or gender are linked to these actions as normative elements to the evaluation of programs or policies, but not as autonomous fields of study of the housing.In addition to this central concern, a significant growth of academic  production and  ome indication of the internationalization of research are mentioned
