NEARLY three-quarters of Americans wish China would "just hurry up and overtake America already," according to a new survey by The Economist Simulation Unit, published on April 1st. Constant worrying about exactly when the superpower will fall into second place is causing anxiety throughout American society, the survey found. "Will it be 2015? 2020? 2025?

The report examines in detail the relationship between the two countries and finds that in some important fields, China has already surpassed America. A summary of the findings is presented below.
