The term yizu (蚁族), or “ant tribe,” refers to unemployed college graduates born after 1980 — in other words, the crop of college graduates over the past two years — who generally live on the margins of China’s cities, in urbanizing villages or districts where they can find cheaper housing and search for economic opportunities. The yizu, as a young, restless and educated new segment of Chinese society, are a growing social concern for the government as a potential source of instability. According to a report from the Chinese Academy of Social Sciences released in June 2010, yizu now number more than one million nationwide, and an estimated 100,000 live in Beijing alone.
