On the basis of the sectoral growth projection it is expected that there will be little improvement in the unemployment situation in the future. The ratio of unemployment to total labour force is expected to go down to 13 % in 1975 from 18 % in 1960. There was no change in the unemployment position between 1956 and 1960. The structure of the economy will not be appreciably changed either as may be seen from the percentage distribution of the GDP at factor cost by industrial origin (Table 2. 5. viii). Except for livestock, forestry and fishing, mining, chemicals, engineering, other manufacturing, fuel and power, banking and insurance, the percentage contributions of the other sectors have either remained stationary over the years or declined to some extent. However, the absolute amounts of GDP from chemicals, engineering, fuel and power, and even other manufacturing, are so small that the economy will still remain predominantly agricultural, or, if we bring in forestry and mining, will be based on primary industries only. Estimates given in Table 6b of expenditure, GDP, GNP, and national income, and per capital figures for each based on the low rate of population increase (which seems to be more acceptable than the high rate), show that after 1965 the economy of British Guiana will lapse again to a stagnant period. Unless there are more investments in the economy than are envisaged in our projection, the growth in national income will be barely suffi- cient to maintain the per capital income level reached in 1965. This is mainly because of the high rate of population growth, an exponential rate of 2.849 % annually, and also our conservative estimate of future growth of the economy. Even if the exports will be higher than imports from 1965 onwards, it is rather difficult to anticipate considerably higher invest- ments in the economy either by the government because of high public debt charges, or by the private entrepreneurs with their faith in British Guiana shaken by political strife and turmoil.
