GENUS - Journal of Population Sciences - is an open access peer-reviewed journal published by Springer on behalf of the Sapienza University of Rome. Founded in 1934 by Corrado Gini, GENUS has always adopted an interdisciplinary approach to population studies. In keeping with the times – particularly in 1965-1992 under Nora Federici, and in 1993-2008 under Antonio Golini as directors – an increasing number of articles have been published on general population theories, population dynamics and mathematical demography. Graziella Caselli has directed the journal in the period 2009-2010, continuing as Editor in Chief since then. Viviana Egidi was appointed Director in Chief in 2011 and has maintained the direction till 2018. The journal has an interdisciplinary focus by publishing articles of “pure” demography and articles aiming to further a better knowledge of the interrelationship between demography and biological, social and economic phenomena, connected with the evolution of the population. GENUS promotes open dialogue across cultural, ideological and at times theoretical walls in the attempt to understand the complexities underlying population issues. GENUS is published under the auspices of AISP - Italian Association for Population Studies.
