The role of residential mobility in reproducing socioeconomic stratification during the transition to adulthood.

ABSTRACT: OBJECTIVE:This study assesses whether frequency of residential mobility plays a role in the reproduction of socioeconomic inequality during the transition to adulthood based on two criteria: (1) selection - is there socioeconomic sorting into residential trajectories? - and (2) lack of moderation - is this sorting irreducible to other life events that prompt moves (e.g., changes in employment status)? METHODS:I use two and a half years of monthly address data from the Relationship Dynamics and Social Life data set, a sample of 18- and 19-year-old young women in a Michigan county. As an improvement upon previous measures of residential mobility, I use group-based trajectory analysis to categorize young women into residential trajectory groups. I then conduct a series of nested logistic regressions to predict membership in residential trajectory groups and a decomposition analysis to determine whether rapid movers are exposed to more life events (e.g., entering/exiting employment) or are simply more sensitive to moving in the face of life events compared to gradual movers. RESULTS:Rapid moving is associated with low socioeconomic status. Rapid movers experience similar family formation, employment, and academic changes as gradual movers but are more likely to move when faced with these life events. CONCLUSIONS:High residential mobility is a phenomenon among early home-leavers as part of an accelerated and underfunded transition to adulthood rather than a reflection of the upward socioeconomic mobility of college students. CONTRIBUTION:High residential mobility is not simply a neutral or normative aspect of the transition to adulthood but rather part of the process of reproducing socioeconomic stratification.

Project description:BackgroundMany epidemiological studies assign exposure to an individual's residence at a single time point, such as birth or death. This approach makes no allowance for migration and may result in exposure error, leading to reduced study power and biased risk estimates. Pregnancy outcomes are less susceptible to this bias, however data from North American populations indicate that pregnant women are a highly mobile group. We assessed mobility in pregnant women in the north of England using data from the Northern Congenital Abnormality Survey (NorCAS).MethodsData were extracted from NorCAS for 1985 to 2003. Eligible cases had a gestational age at delivery of > or = 24 weeks (a viable delivery) (n = 11 559). We assessed mobility between booking appointment (average gestational age 13 weeks) and delivery for pregnancies where the address at booking appointment and delivery were known. The impacts on mobility of maternal age and area-level socio-economic indicators were explored using standard descriptive statistics. A sensitivity analysis and a small validation exercise were undertaken to assess the impact of missing data on the estimate of mobility.ResultsOut of 7 919 eligible cases for whom addresses at booking and delivery were known, 705 (8.9% (95% CI 8.3 - 9.5)) moved between booking and delivery; the mean and median moving distance was 9.7 and 1.4 km respectively. Movers were significantly younger (25.4 versus 27.3 years, p < 0.01) and lived in more deprived areas (index of multiple deprivation score 38.3 versus 33.7, p < 0.01) than non movers.ConclusionMobility in the north of England (9%) is considerably lower than that reported in North America and the only other study from the UK (23%). Consistent with other studies, mobility was related to maternal age and socio-economic status, and the majority of moves were over a relatively short distance. Although this population appears relatively stable, the mobility we have observed may still introduce misclassification or error into an exposure assessment relying solely on postcode at delivery, and migration should still therefore be considered a potential source of bias in future studies.

Project description:BackgroundPrenatal exposure to outdoor air pollution has been shown to have health effects in many studies; low birth weight, preterm delivery, small for gestational age, and stillbirth are the most often cited. However, exposure of pregnant women is difficult to quantify, especially with regard to their mobility, which is rarely taken into account in epidemiological studies. This study aimed to assess the impact of mobility of pregnant women living in Paris, France, on their exposure estimates to nitrogen dioxide (NO2).MethodsA total of 486 pregnant women were recruited in 5 maternity hospitals in Paris between January and April 2016. A questionnaire was used to collect mothers' characteristics (demography, education, etc.) and to assess their daily mobility during pregnancy (time spent at work, commuting time and mode used to move from residential to occupational places). Daily NO2 concentrations were estimated based on the combination of annual average concentrations modeled at the census block scale and daily concentrations measured from fixed monitoring stations. Different models were used to compare the exposure of pregnant women in residential and occupational places, also taking into account travel time and travel mode. The socioeconomic profile of the census blocks was characterized using a multi-component index.ResultsDuring the first trimester of pregnancy, women living in the least deprived census blocks were exposed to higher concentrations of NO2 than those living in the most deprived ones. Occupational mobility had a small impact on exposure levels (average increase after taking account of mobility: +?0.52 ?g/m3) which was not related to the socioeconomic profile of the women. The commuting mode made a greater difference (+?1.46 ?g/m3 on average), in particular among women living in the most deprived census blocks.ConclusionsOur study illustrates that air pollution exposure can be underestimated when ignoring occupational mobility and commuting mode of pregnant women. This effect might be differential according to the neighborhood deprivation profile.
