The economy grew a real 0.5 percent in the October-December quarter, unchanged from a preliminary report released in mid-February, the government said Tuesday.

The growth, measured in terms of gross domestic product, translates into an annualized expansion of 2.2 percent, revised upward from the earlier reported 2 percent growth, the Cabinet Office said.

The revised figures make it possible for the government to attain its fiscal 2002 GDP target of 0.9 percent growth even with a 3.6 percent contraction in the January-March quarter.
