Ethnic exposure in activity places
With increasing ethnic diversity, the high level of segregation between ethnic groups remains a major social problem in many cities. This study provides detailed insight into activity space segregation by analysing ethnic exposure across all activity places people visit, aiming to detect where ethnic groups are more exposed to each other and where they are more separated. Our study is based on survey and smartphone tracking data collected over a …
Does a Small Country Have Meaningful Regional Personality Differences? The Case of Estonia
BACKGROUND: Regional differences in the Big Five personality domains have been observed in several countries at different geographical granularities, often correlating with regional political, economic, social, and health (PESH) indicators. OBJECTIVE: We examined the extent of regional personality differences in Estonia and whether these differences were meaningfully correlated with PESH indicators. METHODS: Using data from the Estonian Biobank (…
Differences in bike-sharing usage and its associations with station-surrounding characteristics
The bike-sharing system offers a wide range of benefits to promote human mobility for all. However, many bike-sharing systems are most used by specific demographic groups (e.g., younger people and males), suggesting that the resulting benefits are not equally distributed among the public. We aim to empirically examine the differences in bike-sharing usage among varying demographic groups and its association with station-surrounding characteristic…

Transnationalism in the digital age
People who are simultaneously embedded into multiple countries are referred to as transnationals. We have investigated the influence of information and communications technology (ICT) on the transnational communities of Estonia, one of the world’s frontline countries when it comes to technological usage. We conducted interviews with Estonians who permanently live abroad to discover how ICT helps them stay connected with their country of origin. T…
Does personality predict traveling abroad as indicated by mobile phone data? The idea of the mobile personality revisited
The present study examines the associations between the Five-Factor Model personality traits and the trips abroad over a period of 12 months in a sample of 349 adults by using Call Detail Records. Our findings show that the modern-day traveler is likely younger, open to new values (O6) and experiences (O4) and seeking novelty and excitement (E5). Higher Extraversion, especially higher levels of social dominance (E3) and energy (E4), and higher sp…
Temporary population mobilities between Estonia and Finland based on mobile phone data and the emergence of a cross-border region
People move for various purposes and lengths of time. Temporary mobilities across borders have become increasingly important but are difficult to observe. In considering temporary population mobilities between Estonia and Finland, the present focus is on the volumes of temporary mobility, characteristics of visits, visitor types, temporal rhythms, distribution of visits to destinations, and their contribution to the emergence of a cross-border re…
The Relationship between Ethno-Linguistic Composition of Social Networks and Activity Space
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 ci…
Spatial Underpinnings of Social Inequalities
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…
Identifying relationships between personal social networks and spatial mobility
Knowledge about the relationship between the spatial organisation of personal social networks and physical mobility is important for understanding spatial problems and social inequalities that are inseparable from spatial and social structures. To provide further insights into these relationships, this study investigates the link between the spatial distribution of individuals' social networks and spatial mobility. We collected data from a group …
The Link Between Ethnic Segregation and Socio‐Economic Status
The extent to which ethnic segregation results from differences in socio‐economic factors remains a seminal topic of debate. The growing literature demonstrating the multifaceted phenomenon of segregation urges more focus on individuals’ spatial and social interactions. We applied an activity space approach and considered ethnic differences in individuals’ activity spaces as an indicator of spatial segregation. We used mobile phone and survey dat…
An ethno-linguistic dimension in transnational activity space measured with mobile phone data
In addition to permanent migration, different forms of cross-border mobility were on the rise before the COVID-19 pandemic, ranging from tourism to job-related commuting. In this paper ethno-linguistic differences in cross-border mobility using the activity space framework are considered. New segregation theories emphasise that segregation in one part of the activity space (e.g. in residential neighbourhood) affects the segregation in other parts…
Methodological framework for producing national tourism statistics from mobile positioning data
Due to the ongoing increase in daily mobility, reductions in border controls, and new trends in tourism, it is important to find new ways to record comprehensively the growing number of tourists. This paper describes a method of extracting cross-border statistics on tourism from roaming call activities found within passive mobile positioning data. Eesti Pank (the central bank of Estonia) has been using these data and methodology since 2008 to cal…
Generational differences in spatial mobility
This article focuses on generational differences in spatial mobility. Assuming that the ability to cope with the social transformations related to growing mobility varies significantly across generations, we use mobile positioning data collected in Estonia during 2014 providing four main indicators, namely, the number of locations visited and the distances between visited locations, within Estonia and abroad. The results indicate that spatial mob…
Are younger age groups less segregated? Measuring ethnic segregation in activity spaces using mobile phone data
Both assimilation theory and common sense suggest that the longer the immigrants reside in a host society, the more they become integrated. However, studies conducted in many countries show the opposite: younger generations of immigrants are more segregated than their parents. The aim of this study is to examine differences in ethnic segregation between age groups of the Estonian majority and Russian-speaking minority in Estonia. We use census da…
The Relationship between Social Networks and Spatial Mobility
Relationships between individuals and their social networks have a significant influence on spatial mobility and transportation needs. This article focuses on networks of calling partners using mobile phones and spatial mobility in Estonia. Mobile phone call graphs and call detail record (CDR) data have been used for this study. Our investigation indicates that the larger one’s network of calling partners using mobile phones and the larger the ge…
Ethnic Segregation During Public and National Holidays
This paper contains an analysis of ethnic differences in activity locations during public and national holidays. Holidays relate to identity, and the celebration of holidays can be a very important part of acculturation processes and are therefore relevant to ethnic integration policies. We study the out‐of‐home nonemployment activity locations of 12,500 respondents in Estonia, using mobile phone positioning data. The results show that during hol…
Evaluating the Travel Distances of Events Visitors and Regular Visitors Using Mobile Positioning Data
Event tourism has become an important economic component of modern tourism, given the growing numbers of visitors and the development of local communities that it entails. This study examines whether the distances traveled by foreign visitors to events differ from those traveled by non-event (i.e., regular) visitors, and which factors influence such distances. We use passive mobile positioning data obtained from visitors to 145 events in Estonia …
The temporal variation of ethnic segregation in a city
The aim of this study is to determine the temporal variation of ethnic segregation in the city of Tallinn, the capital of Estonia. We employ data on mobile-phone use to compare variations in segregation indices during the day, the week, and the year. The results indicate that the locations of people are more segregated at night, with considerably less segregation during the daytime. The segregation is significantly lower on workdays compared to w…
Ethnic Differences in Activity Spaces
The need to examine the entire scope of everyday activities of individuals in segregation studies has recently been recognized by social scientists and policy makers. To bring forth new insights into ethnic segregation through investigating the activities and movement undertaken by different population groups, we used mobile phone positioning data to compare the activity spaces of out-of-home nonemployment activities over a one-year period in Est…
