Comparison to Western Concepts: This is fundamentally different from “latchkey kids” or children of divorced parents in the West. A “latchkey kid” might be alone for a few hours after school. A `留守儿童` can be separated from their parents for most of the year, for many years in a row. The separation is not due to family breakdown but is a calculated economic decision driven by systemic factors like the
户口 (hùkǒu) system. This system acts as a barrier, making it prohibitively expensive or impossible for migrant children to attend city schools, forcing them to stay in their rural hometowns.
