In a great many countries gross domestic investment actually declined during the 1980s, and that pattern clearly must be reversed if even minimum growth objectives are to be attained. During the period 1980-1986, investment increased at an extraordinarily rapid rate in China (19.3% per annum) and at a modest rate in India (4.6% per annum). In the other low-income economies as a group, however, investment increased only 0.4% per annum, which implies a heavily negative rate of growth in per capita terms. In the middle-income economies the growth of investment was negative, and the lower middle-income economies fared worse than the upper middle-income ones. The most serious situation as regards investment occurred in two overlapping groups of countries - sub-Saharan Africa and the highly indebted countries. In sub-Saharan Africa gross investment declined at an annual rate of 9.3% a year, and in the highly indebted countries it declined by 6.3% a year.
