As can be seen from the graph, there is a steadily increasing tendency of personal computers in households in China. In 1980, only two families in every one thousand families possessed a personal computer. However, in 1981, there were forty families in every one thousand families owned a computer. The figure is twenty times of that in 1980. From then on, the line continued to go up until 1987 when two hundred families in every one thousand families had a personal computer; this is one hundred times of that in 1980. In 1988, the rate of family computer reached as high as two hundred and ten in every thousand families.
