Place of living has been associated with a variety of effects but is often considered stationary. Newer research reveals that the accumulation of deprivation conveys many of the effects that were initially thought to be captured by place of birth or current place of living; however, the view of accumulation as a static entity implies that only the length of residency matters. This study uses registry data to follow a cohort (N = 256,345) from birth to age 30 years. It investigates the effects of prolonged exposure to deprived neighborhoods on educational attainment and examines whether these effects are the same for those who accumulate exposure at different times. The study finds that exposure is important for educational attainment but that the effect differs at different life stages.
