Abstract
Studies of neighbourhood effects typically measure the neighbourhood context at one specific spatial scale. It is increasingly acknowledged, however, that the mechanisms through which the residential context affects individual outcomes may operate at different spatial scales, ranging from the very immediate environment to the metropolitan region. We take a multi-scale approach to investigate the extent to which concentrated poverty in adolescence is related to obtained education level and income later in life, by measuring the residential context as bespoke neighbourhoods at five geographical scales that range from areas encompassing the 200 nearest neighbours to areas that include the 200k+ nearest neighbours. We use individual-level geocoded longitudinal register data from Sweden and the Netherlands to follow 15/16-year-olds until they are 30 years old. The findings show that the contextual effects on education are very similar in both countries. Living in a poor area as a teenager is related to a lower obtained educational level when people are in their late 20s. This relationship, however, is stronger for lower spatial scales. We also find effects of contextual poverty on income in both countries. Overall, this effect is stronger in the Netherlands than in Sweden. Partly, this is related to differences in spatial structure. If only individuals in densely populated areas in Sweden are considered, effects on income are similar across the two countries and income effects are more stable across spatial scales. Overall, we find important evidence that the scalar properties of neighbourhood effects differ across life-course outcomes.
Introduction
For a long time, it has been theorised that living in areas of concentrated poverty restricts the opportunities of residents and has a negative effect on individuals’ socio-economic status (Brooks-Gunn et al., 1997; Leventhal and Brooks-Gunn, 2000; McKenzie et al., 1967; Wilson, 1987). Many studies have examined these so-called neighbourhood effects on socio-economic outcomes, including income and educational achievement. Some of these studies focus on adult exposure and adult outcome (Galster et al., 2008; van Ham and Manley, 2010), while other studies investigate adult or youth outcomes in relation to exposure in childhood and adolescence (Andersson and Subramanian, 2006; Andersson et al., 2021; Chetty et al., 2016; Nieuwenhuis et al., 2021; van Ham et al., 2014).
In recent years, many important steps forward have been taken in the field of neighbourhood effects. Scholars moved from point-in-time measures to taking neighbourhood histories of individuals into account (Andersson, 2004; Hedman et al., 2015; Musterd et al., 2012; Sharkey, 2008), found ways to control for non-random neighbourhood selection (Troost et al., 2022; van Ham et al., 2018) and used alternative definitions and operationalisations of neighbourhoods by moving from administrative units to bespoke neighbourhoods in order to circumvent the Modifiable Areal Unit Problem (Hipp and Boessen, 2013; MacAllister et al., 2001; Malmberg et al., 2011).
Another important refinement in the neighbourhood effects literature is the adoption of a multi-scale approach. Neighbourhood effects (also referred to as spatial context effects) are multi-scalar in nature, as different processes play at different spatial scales (Andersson and Malmberg, 2015, 2018; Andersson et al., 2018; Fowler, 2016; Knies et al., 2021; Petrović et al., 2018). Bespoke neighbourhoods are spatially flexible and can be constructed at multiple geographical scales (Johnston et al., 2004). It is now increasingly acknowledged that there is not one correct scale to measure the residential context and that neighbourhood effects must be investigated as a multi-scale phenomenon.
In the current study, we investigate how exposure to contextual poverty at multiple spatial scales in adolescence is related to obtained educational level and income in adulthood. There are several causal mechanisms that can explain how the concentration of poverty in the residential area might be related to socio-economic outcomes later in life such as collective socialisation, social control and cohesion and access to job opportunities (Ainsworth, 2002; Galster, 2012; Sampson, 2012; Wilson, 1987: 198). These mechanisms may operate on different spatial scales (Galster and Sharkey, 2017; Sharkey and Faber, 2014). For example, peer group effects and role model effects can be expected to have an influence at the very low scale, in people’s immediate residential environment. At more intermediate scales, institutional mechanisms and stigma effects can play a role, and at much higher scales, regional labour market effects may influence individual socio-economic outcomes (Andersson and Malmberg, 2015). Despite the fact that there are good theoretical reasons to investigate neighbourhood effects on multiple scales, many empirical studies of neighbourhood effects include the spatial context at just one spatial scale, often using administrative spatial units.
The aim of the current study is to come to a better understanding of the effect of exposure to contextual poverty in adolescence on individual socio-economic outcomes in adulthood. We examined the extent to which contextual poverty concentration is related to obtained educational level and income, over and above family characteristics related to education and income. We took a longitudinal approach, by measuring the concentration of poverty in the residential area at age 15/16 and obtaining educational level and income at age 30. Whereas previous studies were often limited to using relatively large pre-defined administrative areas to measure contextual poverty, we used bespoke neighbourhoods and explicitly took a multi-scale approach. We examined the effect of contextual poverty at five different spatial scales, ranging from very small (i.e. 200 nearest neighbours) to large (i.e. 204,800 nearest neighbours). Finally, we tested the possible generality of these multi-scale effects by comparing Sweden and the Netherlands. It is possible that neighbourhood effects (on educational achievement and income) will differ in countries with different segregation patterns and that have different welfare state regimes (Andersson et al., 2018). We compared patterns of contextual poverty at multiple scales between the two countries and analysed identical models for the effects of contextual poverty experienced in adolescence on obtained education and income for Sweden and the Netherlands.
Theoretical and methodological considerations
Mechanisms at multiple scales
The literature on neighbourhood effects provides strong conceptual support for the idea that neighbourhood effects vary with spatial scale (Andersson and Malmberg, 2015; Andersson and Musterd, 2010; Petrović et al., 2020; van Ham et al., 2012). Based on the idea of multi-scale effects, it has been suggested that it is better to refer to residential context, contextual area effects or residential environment effects, rather than neighbourhood effects, because many effects are likely to play out at different scales than the neighbourhood (Petrović, 2020; Sharkey and Faber, 2014). Conceptually, social and institutional mechanisms related to the spatial context in which one lives are connected to different spatial scales. Having said that, it is not immediately clear from the literature how small or large areas should be in order to influence the outcomes of individual levels of education and income (Friedrichs, 2016). That is, at what levels do relevant social mechanisms operate concerning income and education?
To better understand the different mechanisms at different spatial scales, one could think of influence on education according to
The literature on residential context effects also provides some ideas of the different spatial scales which are relevant for the understanding of the two outcome variables for this study: education and income. For

Cross-national comparison: Sweden and the Netherlands
There are two main reasons why a cross-national comparison is fruitful for residential context effects research. First, contextual effects of poverty on educational attainment and income level can differ between countries as segregation levels and patterns in turn are different. Second, these contextual effects can also differ between countries that have different welfare state regimes. Even when poverty levels and spatial patterns of poverty are similar between countries, the magnitude of residential context effects can differ according to the welfare system. One system might compensate for negative context effects more strongly than the other. The fact that Korpi and Palme (1998) label Sweden as having an encompassing welfare model, and label the Netherlands as having a basic security welfare model, could be of importance here. Esping-Andersen (1999), on the other hand, classifies the two countries as belonging to the same universalist welfare state regime, something that is also reflected in the redistributive budget size and income redistribution of Sweden and the Netherlands, as reported by Korpi and Palme (1998). Thus, at this stage, it is not clear how variation in welfare state arrangements between Sweden and the Netherlands can be expected to have consequences for the differences in how residential contexts influence individual-level outcomes between the two countries. (For extensive reading of country and city comparisons, see Haandrikman et al., 2021; Musterd, 2005; van Ham et al., 2021.)
Bespoke neighbourhoods
Especially when doing cross-national studies of contextual effects, it is important to carefully choose the same and specific geographical scale for the analyses, as using different scales can affect the outcomes of the comparison (Andersson and Malmberg, 2015; Andersson and Musterd, 2010; Andersson et al., 2018: 201). Large-scale geographic areas hide homogenous pockets of poverty concentration, whereas areas which are too small can overstate contextual poverty concentration as small areas often are more homogenous. Thus, the degree of poverty concentration cannot be compared between countries if one has systematically differently sized areas (Andersson et al., 2018). In recent years, the increasing availability of individual-level geocoded data has led scholars from different fields to use bespoke neighbourhoods to measure spatial contexts. Different terms are used to label bespoke neighbourhoods, including individualised neighbourhoods, scalable neighbourhoods, egocentric neighbourhoods, egocentric buffers, egohoods, overlapping neighbourhoods and individual social environments (Hipp and Boessen, 2013; MacAllister et al., 2001; Malmberg et al., 2011).
A method to create such bespoke neighbourhoods determines neighbourhoods based on a predetermined equal number of nearest neighbours (e.g. Malmberg et al., 2011; Östh et al., 2015). This

Data and methods
Data
Data for this study come from national population register data from the Netherlands and Sweden. For the Nether-lands, the data source is the Social Statistical Database (SSD, or Social Statistisch Bestand (SSB)) (Bakker, 2002; Houbiers, 2004). The SSD data cover the entire population of the Netherlands since 1999 and contain data from a range of government registers, including population, tax and housing registers. The data are geocoded at the level of 100 × 100 m grids for the whole country. The data for Sweden originate from Statistics Sweden’s registers in a project called Migrant Trajectories covering the years 1990–2016. Data are accessed through an online system called MONA (Statistics Sweden, 2018). The Swedish data are geocoded at the level of 250 × 250 m grid cells in urban areas (defined as localities consisting of a group of buildings normally not more than 200 m apart from each other, and with at least 200 inhabitants), and 1000 m squares outside these urban areas, based on the 2010 urban subdivision. The urban and rural grids are positioned in such a way that 16 urban grid cells can fit into one rural grid cell (see Nielsen et al., 2017: 24–25).

For the Netherlands, we studied the 1987 birth cohort (

Obtained education level and income (age 30)
We used two individual outcome variables: obtained educational level and individual earned income at age 30.
Individual and family characteristics (age 15/16)
As individual-level predictors of income, we included sex (with female as the reference category), and a non-European migration background, which indicated whether at least one parent was born outside of Europe. We included a set of family and parental characteristics when the individual was 15/16 years of age as predictors of individual income and educational level. We included a dummy variable that indicated whether the individual was living in a single-parent household (single-mother household in Sweden). Another dummy variable indicated whether the family received a social allowance. Household income in thousand Euros was included as a continuous variable. Parental tertiary education was included as a categorical variable, with three categories indicating whether no, one or both parent(s) had tertiary education. Parental unemployment was also included as a categorical variable, with three categories indicating whether no, one or both parent(s) were unemployed.
Contextual at-risk-of-poverty rate at multiple spatial scales (age 15/16)
The contextual at-risk-of-poverty rate is measured in a similar way in both countries and is based on the population of individuals aged 25 or older. It is based on the Eurostat definition of the at-risk-of-poverty rate, which is defined as the share of people with an equivalised disposable household income below the at-risk-of-poverty threshold, which is set at 60% of the national median equivalised disposable income (Eurostat, 2018).
We calculated bespoke measures of contextual poverty at multiple geographical scales using EquiPop, a software programme for the calculation of the
Analytical approach
First, we analysed the patterns of the concentration of at-risk-of-poverty households at multiple geographical scales. In order to compare concentrations of poverty across countries, we followed the approach of Andersson et al. (2018) and present percentile plots of these concentrations at different scales.
Second, we estimated two series of identical linear regression models predicting obtained educational level and income at age 30 in both countries. In Model 1, we only included lagged effects of individual and family characteristics at age 15/16. Here, we used a formal test (

In a final step, we have re-estimated Swedish models using only observations from more densely populated areas. The cut-off point selected for less densely populated areas was that a radius greater than 330 km was needed in order to reach the highest population threshold,

First, we present the results of the longitudinal models predicting educational level and income at age 30 with only individual and family characteristics at age 15/16 (Table 2). In both countries, males have a higher income than females. In contrast, males are less highly educated than females. The latter effect, of having lower education due to being male, is slightly stronger in Sweden (

The effects of the variables that present the socio-economic status of the family when the individual was 16 years old are all significantly different between Sweden and the Netherlands. Individuals who had a single parent at age 15/16 had a lower educational level and income at age 30, compared to individuals who had a two-parent family. For both education and income, this single-parent effect is stronger in the Netherlands than it is in Sweden (
However, having a family on social allowance or unemployed parents at age 15/16 has a stronger negative impact in Sweden than in the Netherlands for both educational outcome and income. For educational achievements, the positive effect of having one or two parents with tertiary education is stronger in Sweden (
In total, these individual and family characteristics explained 9.1% of the variance in educational level in the Netherlands and 17.3% in Sweden. The variance explained regarding income in adulthood is 8.4% in the Netherlands and differs from the 6.4% in Sweden.
Multi-scale contextual poverty (age 15/16) as a predictor of educational level and income (age 30)
In Table 3, results are presented from the models that estimated the association between the contextual at-risk-of-poverty rate at age 15/16 and obtained educational level at age 30 in Sweden and the Netherlands. All individual and family characteristics that were included in Model 1 (Table 2) were also included in the models of Table 3, but are not reported.
Educational level (years) at age 30 predicted by contextual poverty (ratios) at age 15/16 at multiple geographical scales in the Netherlands and Sweden.
In both countries, the contextual at-risk-of-poverty rate is clearly related to a lower obtained educational level at age 30. The size of the effect, however, decreases with increasing spatial scale. Contextual poverty at a lower spatial scale, among the neighbours that are closest to an individual, has stronger negative consequences for obtained educational level than the at-risk-of-poverty rate at a higher spatial scale. The results show that the effect of contextual poverty at a low spatial scale is stronger in the Netherlands compared to Sweden. At a high spatial scale, the effect is stronger in Sweden and is even non-significant in the Netherlands.
Table 4 presents the models that estimated the relations between the contextual at-risk-of-poverty rate at age 15/16 at multiple spatial scales and individual income at age 30. Similar to the contextual effects we found for educational level, we found that the contextual at-risk-of-poverty rate is also negatively related to obtained income. However, the contextual effects on income show a different pattern from those on educational level. Whereas the contextual effect of the at-risk-of-poverty rate in Sweden again decreases with increasing spatial scale, the contextual effect for the Netherlands does not change much across scales. The results show that at all spatial scales, except the largest spatial scale (

Conclusion and discussion
In this study, we have examined how socio-economic status later in life is related to the at-risk-of-poverty rate in multi-scalar, residential environments during adolescence, using longitudinal, geocoded register data from the Netherlands and Sweden. In the early 2000s, adolescents in these countries were exposed to very similar variations in at-risk-of-poverty rates in their residential contexts. Thus, a comparison between the Netherlands and Sweden provides valuable information on the extent to which young adult outcomes are related to the neighbourhood context in similar ways across different institutional contexts.
As we see it, the most important result of this study is the contrasting findings regarding neighbourhood effects on education compared to neighbourhood effects on income.
With respect to education, the effects of the individual- and family-level variables, the neighbourhood context and the scalar profile of the contextual effects are very similar across countries. In both Sweden and the Netherlands, a 10 percent-point increase in the poverty rate among the nearest 200 neighbours is associated with a decline in length of education of around 2.5 months. Empirical studies tend to find a link between neighbourhood factors and variation in educational attainment, but still this similarity in results further strengthens the idea that educational aspirations are influenced by neighbourhood experiences. Moreover, in both countries, the strongest effects are found at the smallest neighbourhood scale, with weakening effects for the larger scales. This also suggests that interaction with the closest neighbours is what matters most for educational attainment.
If instead the effects of income are considered, the effects of the individual- and family-level variables, the neighbourhood context and the scalar profile of the contextual effects are quite different between Sweden and the Netherlands. In both countries, there is a negative link between attained income and the poverty rate in the residential context during adolescence, but the estimate for the Netherlands is twice as high as in Sweden at the lowest neighbourhood scale, with an even bigger difference at larger scales. The differences between Sweden and the Netherlands become smaller when individuals in less densely populated regions are excluded. Also, in contrast to the findings for educational attainment, there is less evidence that small-scale contexts are more closely associated with income attainment compared to large-scale contexts. These findings suggest that mechanisms of contextual influence on earnings are more complex than those for educational attainment (e.g. compare Andersson, 2004; Brännström, 2005; Brattbakk and Wessel, 2013; Musterd et al., 2012). Earnings may, for example, depend not only on role models and peer influence in the direct living environment but also on the formation of social networks, and on the opportunity structure of the local economy at larger spatial scales.
Our results, thus, give support to the idea that neighbourhood effects on earnings are at least partly based on mechanisms different from the mechanisms that are considered important for neighbourhood effects (e.g. role models, peer effects) on the formation of educational aspirations.
From the above findings, we conclude that not only is there a tendency for at-risk-of-poverty individuals to be sorted into neighbourhoods in similar ways across countries, but it is also the case that the effects of concentrated poverty are similar in different country contexts; adolescents growing up in residential contexts with high poverty rates are bearing that mark into adulthood, with lower earnings and a lower level of education in their early 30s.
