Monitoring the ways in which childhood socioeconomic environment is associated with adult outcomes is fundamental in terms of informing evidence-based debates. However, we know little about the cohort differences in the association of childhood income with adult outcomes in Finland, a country of low economic inequality and one of the most desegregated educational systems in the OECD countries. We use register data on cohorts born in 1981−89. We divide these cohorts into tenths by their parental, school and postcode-level aggregated income at the age of 15. We focus on five adult outcomes at the age of 30. On average across the cohorts, compared to the highest income groups, the lowest tenth of parental, school and postcode income had, respectively, a 1.8, 1.7 and 1.4-fold risk of death, 3, 1.3 and 0.9-fold risk of low education, 2.5, 1.8, and 1.4-fold risk of long-term unemployment. People with a lower childhood parental or school income were more likely to live with a partner and have children than people from higher income backgrounds. The differences by school and postcode income in the education outcome were small. We observe increasing differences in the education and employment outcomes by parental and, to a lesser extent, school income.探究儿童时期社会经济环境与成年结局间的关联，对开展循证辩论具有基础性意义。然而，在经济不平等程度较低、且为经合组织（OECD）成员国中教育社会融合程度最高的国家之一的芬兰，学界对儿童时期收入与成年结局关联的队列差异仍知之甚少。本研究采用1981年至1989年出生队列的登记数据，以研究对象15岁时的父母收入、学校层面汇总收入以及邮政编码区域汇总收入为划分依据，将所有队列分为十个收入分位组。本研究聚焦于研究对象30岁时的五项成年结局指标。在所有队列的平均水平上，相较于最高收入组，父母收入、学校层面收入、邮政编码区域收入最低的十分位组，其死亡风险分别为最高组的1.8倍、1.7倍与1.4倍；低学历风险分别为3倍、1.3倍与0.9倍；长期失业风险分别为2.5倍、1.8倍与1.4倍。童年时期父母收入或学校层面收入较低的人群，相较来自高收入家庭背景的人群，更有可能与伴侣共同生活并生育子女。学校层面收入与邮政编码区域收入在学历结局上的差异相对较小。我们观察到，父母收入对学历与就业结局的差异影响呈扩大趋势，而学校层面收入的此类影响程度相对有限。
