A Longitudinal Study of Early Adult Neighborhood Careers of Siblings

Journal article (2020) - David Manley, Maarten van Ham, Lina Hedman
Understanding how inequalities are transmitted through generations and restrict upward spatial mobility has long been a concern of geographic research. Previous research has identified that the neighborhood in which someone grows up is highly predictive of the type of neighborhood he or she will live in as an independent adult. What remains largely unknown is the relative contribution of geography compared to the contribution of the family context in forming these individual life outcomes. The aim of this article is to better understand the role of the spatial–temporal contexts of individuals in shaping later life outcomes, by distinguishing between inherited disadvantage (socioeconomic position) and spatial disadvantage (the environmental context in which children grow up). We use a sibling design to analyze the neighborhood careers of adults after they have left the parental home, separating out the roles of the family from that of the neighborhood in determining residential careers. We employ rich Swedish Register data to construct a quasi-experimental family design to analyze residential outcomes for sibling pairs and contrast real siblings against a control group of “contextual siblings.” We find that real siblings live more similar lives in terms of neighborhood experiences during their independent residential careers than contextual sibling pairs but that this difference decreases over time. The results show the importance of geography, revealing long-lasting stickiness of spatial–temporal contexts of childhood. ...

Evidence from four European countries with different inequality and segregation contexts

Journal article (2020) - Jaap Nieuwenhuis, Tiit Tammaru, Maarten van Ham, Lina Hedman, David Manley
The neighbourhood in which people live reflects their social class and preferences, so studying socio-spatial mobility between neighbourhood types gives insight into the openness of spatial class structures of societies and into the ability of people to leave disadvantaged neighbourhoods. In this paper we study the extent to which people move between different types of neighbourhoods by socio-economic status in different inequality and segregation contexts in four European countries: Sweden, the Netherlands, the UK (England and Wales), and Estonia. The study is based on population registers and census data for the 2001–2011 period. For England and Wales, which has long had high levels of income inequalities and high levels of socio-economic segregation, we find that levels of mobility between neighbourhood types are low and opportunities to move to more socio-economically advantaged neighbourhoods are modest. In Estonia, which used to be one of the most equal and least segregated countries in Europe, and now is one of the most unequal countries, we find high levels of mobility, but these reproduce segregation patterns and it is difficult to move to less deprived neighbourhoods for those in the most deprived neighbourhoods. In the Netherlands and Sweden, where income inequalities are the smallest, it is the easiest to move from the most deprived to less deprived neighbourhoods. The conclusion is that the combination of high levels of income inequalities and high levels of spatial segregation tend to lead to a vicious circle of segregation for low-income groups, where it is difficult to undertake upward socio-spatial mobility. ...
Journal article (2019) - Lina Hedman, David Manley, Maarten Van Ham
Previous research has reported evidence of intergenerational transmissions of neighbourhood status and social and economic outcomes later in life. Research also shows neighbourhood effects on adult incomes of both childhood and adult neighbourhood experiences. However, these estimates of neighbourhood effects may be biased because confounding factors originating from the childhood family context. It is likely that part of the neighbourhood effects observed for adults, are actually lingering effects of the family in which someone grew up. This study uses a sibling design to disentangle family and neighbourhood effects on income, with contextual sibling pairs used as a control group. The sibling design helps us to separate the effects of childhood family and neighbourhood context from adult neighbourhood experiences. Using data from Swedish population registers, including the full Swedish population, we show that the neighbourhood effect on income from both childhood and adult neighbourhood experiences, is biased upwards by the influence of the childhood family context. Ultimately, we conclude that there is a neighbourhood effect on income from adult neighbourhood experiences, but that the childhood neighbourhood effect is actually a childhood family context effect. We find that there is a long lasting effect of the family context on income later in life, and that this effect is strong regardless the individual neighbourhood pathway later in life. ...

A Longitudinal Study of Early Adulthood Neighbourhood Careers of Siblings

Discussion paper (2018) - David Manley, Maarten van Ham, Lina Hedman
Longer term exposure to high poverty neighbourhoods can affect individual socio-economic outcomes later in life. Previous research has shown strong path dependence in individual neighbourhood histories. A growing literature shows that the neighbourhood histories of people is linked to the neighbourhoods of their childhood and parental characteristics. To better understand intergenerational transmission of living in deprived neighbourhoods it is important to distinguish between inherited disadvantage (socio-economic position) and contextual disadvantage (environmental context in which children grow up). The objective of this paper is to come to a better understanding of the effects of inherited and contextual disadvantage on the neighbourhood careers of children once they have left the parental home. We use a quasi-experimental family design exploiting sibling relationships, including real sibling pairs, and "synthetic siblings" who are used as a control group. Using rich register data from Sweden we find that real siblings live more similar lives in terms of neighbourhood experiences during their independent residential career than synthetic sibling pairs. This difference reduces over time. Real siblings are still less different than synthetic pairs but the difference gets smaller with time, indicating a quicker attenuation of the family effect on residential outcomes than the neighbourhood effect ...

A case study of neighbourhood choice in stockholm

Journal article (2018) - Richard P. Mann, Viktoria Spaiser, Lina Hedman, David J.T. Sumpter
We present a non-parametric extension of the conditional logit model, using Gaussian process priors. The conditional logit model is used in quantitative social science for inferring interaction effects between personal features and choice characteristics from observations of individual multinomial decisions, such as where to live, which car to buy or which school to choose. The classic, parametric model presupposes a latent utility function that is a linear combination of choice characteristics and their interactions with personal features. This imposes strong and unrealistic constraints on the form of individuals’ preferences. Extensions using non-linear basis functions derived from the original features can ameliorate this problem but at the cost of high model complexity and increased reliance on the user in model specification. In this paper we develop a non-parametric conditional logit model based on Gaussian process logit models. We demonstrate its application on housing choice data from over 50,000 moving households from the Stockholm area over a two year period to reveal complex homophilic patterns in income, ethnicity and parental status. ...
Discussion paper (2017) - Lina Hedman, Maarten van Ham, Tiit Tammaru
The literature on intergenerational contextual mobility has shown that neighbourhood status is partly "inherited" from parents to children where children who spend their childhood in deprived neighbourhoods are more likely to live in such neighbourhoods also as adults. It has been suggested that such transmission of neighbourhood status also is relevant from multiple generation approach. To our knowledge, however, this has only been confirmed by simulations and not empirical research. This study uses actual empirical data covering 25 years and the full Swedish population to investigate intergenerational similarities in neighbourhood status of three generations of Swedish women. Findings suggest that the neighbourhood environments of Swedish women are correlated with the neighbourhood statuses of their mothers and, to some extent, grandmothers. We also find an effect of distance where intergenerational transmission is stronger for those remaining close. Whereas women whose mothers and grandmothers live in high-income areas benefit from staying close, women whose mothers and grandmothers live in low-income areas do better if they live further away. These results are robust over two different analytical strategies – comparing neighbourhood status of the three generations at similar ages and at the same point in time – and two different spatial scales. We argue that the finding of such effects in (relatively egalitarian) Sweden implies that similar, and possibly stronger, patterns are likely to exist in other countries as well. ...

Previous research has reported evidence of intergenerational transmission of both neighbourhood status and social and economic outcomes later in life; parents influence where their children live as adults and how well they do later in life in terms of their income. However, interactions between the individual, the childhood family and neighbourhood context and the neighbourhood experiences after leaving the parental home are often overlooked which might bias estimates of neighbourhood effects. It is likely that part of the effects attributed to neighbourhoods, are actually effects of the family in which someone was brought up. This study uses a sibling design to disentangle family and neighbourhood effects on income, and synthetic sibling pairs are used as a control group. The sibling design allows us to separate the effects of childhood family and neighbourhood contexts, but also between childhood neighbourhood effects and effects of the adult neighbourhood experiences. Using data from Swedish registers we show that the neighbourhood effect from both childhood and adult neighbourhood exposure is biased upwards by the influence of the family context. This leads to the conclusion that part of what appeared to be a neighbourhood effect was in fact a lasting family effect. Interestingly, we find that there is a long lasting effect of the family context on income later in life, and that this effect is strong regardless the individual neighbourhood pathway later in life. ...

Evidence from Four European Countries with Different Inequality and Segregation Contexts

Discussion paper (2017) - Jaap Nieuwenhuis, Tiit Tammaru, Maarten van Ham, Lina Hedman, David Manley
The neighbourhoods in which people live reflects their social class and preferences, so studying socio-spatial mobility between neighbourhoods gives insight in the openness of spatial class structures of societies and in the ability of people to leave disadvantaged neighbourhoods. We study the extent to which people move between different types of neighbourhoods by socio-economic status in different inequality and segregation contexts in four European countries: Sweden, the Netherlands, the United Kingdom, and Estonia. The study is based on population registers and census data for the 2001–2011 period. For the UK, which has long had high levels of social inequalities and high levels of socioeconomic segregation, we find that levels of mobility between neighbourhood types are low and opportunities to move to more socio-economically advantaged neighbourhoods are modest. In Estonia, which used to be one or the most equal and least segregated countries in Europe and now is one of the most liberal and market oriented countries, we find high levels of mobility, but these reproduce segregation patterns and it is difficult to move to better neighbourhoods for those in the most deprived neighbourhoods. In the Netherlands and Sweden, where social inequalities are the smallest, it is easiest to move from the most deprived to less deprived neighbourhoods. To conclusion, the combination of high levels of social inequalities and high levels of spatial segregation tend to lead to a vicious circle of segregation for low income groups, where it is difficult to undertake both upward social mobility and upward spatial mobility. ...
