With the year-on-year numbers that China has been using, if the statistics bureau says, for example, that China’s economy expanded 9.8% in the fourth quarter of 2010, what they mean is that total output in the fourth quarter of 2010 was 9.8% higher than total output in the final quarter of 2009.
With the adjusted quarter-on-quarter number the U.S. and others use—and which China will start reporting from Friday–when the Bureau of Economic Analysis says the U.S. economy expanded at an annual rate of 3.1% in the fourth quarter of 2010, what they mean is that from the third quarter of 2010 to the fourth quarter of 2010, the U.S. economy grew 0.7%. Multiplying that by four to get the annual rate gives a figure of 3.1%.
In the U.S., Thanksgiving falls in the fourth quarter of the year. Workers eat into turkey and turkey time eats into working days relative to the third quarter. In China, there are also national holidays—notably a week-long national holiday for the Lunar New Year that falls in January or February—that make it more difficult to compare the quarters. It’s not just the holidays themselves that can distort the data: different working patterns in the days before and after as factories gear up and wind down can also have a marked impact.
To correct for these seasonal biases, statisticians look at the pattern of historical data to try and work out the variation between quarters that is caused by seasonal effects (changes in working days and so on) and the variation that is caused by genuine changes in the rate of growth. Using these observations, they can seasonally adjust the raw data for the current quarter to get to the true rate of growth. (Actually, because these calculations are complicated, the statisticians have written computer programs that do the math for them.)
