Comparative Population Studies - Zeitschrift für Bevölkerungswissenschaft (CPoS) is a peer-reviewed interdisciplinary scientific journal on demography and population studies, and publishes articles in English and German. CPoS appears four times a year online, and on an open-access basis. An average of two special issues per year are coordinated by guest editors. Exclusively unpublished peer-reviewed research papers in demography and related fields are published. Papers may cover a wide range of topics on demography, as well as on population or family studies with a focus on empirical or spatial research, theory, and methods. The journal features articles with a perspective on regional issues emphasizing the German-speaking countries and Europe or on population issues on a global scale. Contributions in English or German are welcome at all times. Guest editors for special issues may apply as well.
