In the fourth instalment of The Baseline, our weekly feature on sports statistics, we looked at how overtaking in Formula One has changed over the years.

For decades it appeared the aggressive passing move was a dying art, but everything changed in 2011. Read on to find out why, and what it means for this year’s title tussle between Lewis Hamilton and Nico Rosberg.

As the Financial Times this week examines China’s expansion in Europe, China made an economic leap forward: new data now forecasts that China will officially overtake the US this year to become the world’s largest economy.

Measuring gross domestic product using purchasing power parity (PPPs) the International Monetary Fund now estimates China’s GDP at $17.6tn, against the US’s $17.4tn.

PPPs are an attempt – far from perfect – to account for varying price levels between countries, particularly in goods and services not open to international competition. PPPs make a big difference. According to the IMF, China’s GDP this year measured in simple dollars, making no adjustment for relative prices, is $10.4tn. 

No one knows how many Chinese people live in Europe.

The United Nations estimated Europe’s China-born population at 886,882 in 2010, its most recent count, while Chinese-based social scientists put it somewhere between 2m and 3m.

Why, in the age of big data, is there so much uncertainty where our neighbours are from?
