The authors study the seasonal variability of population in Estonia, and develop a methodology for the monitoring of the short-term mobility of population with mobile-positioning data. The locations of calculated home anchor points of telephone users were analysed by use of the dataset of EMT, Estonia's biggest mobile operator, over a period of 2 years. The results showed that approximately 5% of the population of Estonia change their place of residence seasonally. The number of residents rises during the summer months in coastal areas, the surroundings of cities, and in specific 'dacha' areas. Most of these seasonal migrants originated from cities and towns. The timing and geography of the seasonal migration patterns studied showed the different directions and causes of seasonal moves. The methodology developed for the monitoring of short-term migration is suitable for the monitoring of movements over more extensive territory. In order to determine the causes and composition of these migrations, however, one must use additional survey studies or observations.

A paradigm shift is taking place in spatial segregation research. At the heart of this shift is the understanding of the connectedness of spatial segregation in different life domains and the availability of new datasets that allow for more detailed studies on these connections. In this thematic issue on spatial underpinnings of social inequalities we will outline the foundations of the 'vicious circles of segregation' framework to shed new light on questions such as: What is the role of residential neighbourhoods in urban inequalities in contemporary cities? Have residential neighbourhoods lost their importance in structuring daily lives since important part of social interaction takes place elsewhere? How is residential segregation related to inequalities in other important life domains, in schools, at work and during leisure time? The vicious circles of segregation framework builds on the traditional approaches to spatial segregation, as well as on the emerging new research undertaken within the 'activity space approach' and 'longitudinal approach' to segregation. The articles in this thematic issue improve our understanding of how spatial segregation is transmitted from one life domain to another as people sort into residential neighbourhoods, schools, workplace and leisure time activity sites, and gain contextual effects by getting exposed to and interacting with other people in them.

This study is a contribution to the discussion on the ethnic segregation cycle, through the examination of individuals' activity spaces - including residence and workplace - and from the perspective of social networks. Bridging social ties can be a key factor in higher minority inclusion and in breaking the vicious circle of segregation. We compare the spatial behaviour of two ethno-linguistic population groups living in Tallinn, Estonia's capital city (Estonian-speaking majority and Russian-speaking minority), each of which have co- and interethnic social networks, through the use of mobile positioning (call detail records) and call-graph data. Among our main findings, we show firstly that interethnic social networks are more common for the Russian-speaking minority population. The probability of having an interethnic network is related to the ethno-linguistic composition of the residential district concerned; districts with a higher proportion of residents from another ethnic group tend to favour interethnic networks more. Secondly, the activity space is related to the ethno-linguistic composition of the social networks. Spatial behaviour is most expansive for Estonian speakers with co-ethnic networks, and most constrained for Russian speakers with co-ethnic networks. At the same time, speakers of Estonian and Russian with interethnic networks show rather similar spatial behaviours: They tend to visit more districts where the proportion of people from the other ethno-linguistic group is higher. Interethnic networks are therefore related to spatial behaviour, which can indicate interethnic meeting points and locations, something that is regarded as being important in assimilation and segregation cycle theories.
