2025-11-18
This study examines the impact of family income across various developmental stages of early and later childhood on educational achievement in fifth-grade among Israeli students born between 2000 and 2005. Utilizing administrative data, we analyze the effects of family income during distinct childhood segments, with a particular focus on the critical first 1,000 days of life. Our findings reveal that family income during this early period—from the beginning of pregnancy up to the child's second birthday—has a pronounced and lasting effect on educational outcomes, significantly surpassing the effects of family income in subsequent age segments. Notably, these early effects remain large and significant despite later changes in family income. This research highlights the importance of considering specific age segments within early childhood to achieve a comprehensive understanding of educational stratification dynamics. By delineating the critical role of early-life socioeconomic conditions, this research contributes valuable insights into the factors shaping long-term educational achievement.
