Per capita gross domestic product (GDP) growth among post-1980 globalizing countries accelerated from 1.4 percent a year in the 1960s and 2.9 percent a year in the 1970s to 3.5 percent in the 1980s and 5.0 percent in the 1990s. This acceleration in growth seems even more remarkable given that the rich countries saw steady declines in growth from a high of 4.7 percent in the 1960s to 2.2 percent in the 1990s. Also, the non-globalizing developing countries seem to fare worse than the globalizers, with the formers annual growth rates falling from highs of 3.3 percent during the 1970s to only 1.4 percent during the 1990s. This rapid growth among the globalizers is not simply due to the strong performances of China and India in the 1980s and 1990s—18 out of the 24 globalizers experienced increases in growth, many of them quite substantial.
