Frequently Asked Questions
5 questions
Per-capita productivity differs dramatically: U.S. per-capita GDP is $84,600 vs China's $12,850 (6.6x higher). This reflects the U.S. economy's advanced service sector (80% of GDP), higher wages, and mature capital efficiency. China's economy, while massive in absolute terms, serves 1.42 billion people at lower income levels. A smaller, wealthier population generates higher nominal GDP than a larger, lower-income one.
