14. There has been a decline in the SC main workers from 94.7 per cent in 1991 to 79.0 percent in 2001 Census. This, in turn, has resulted in corresponding increase in the marginal workers from 5.3 per cent in 1991 to 21 per cent in 2001. Out of total workers, ‘agricultural laborers’ constitute 58.5 per cent, which is higher than 12.9 percentage points when compared to 45.6 per cent registered at national level for SC population. ‘Other workers’ account for 29 per cent. Only 10.2 per cent workers have been returned as ‘cultivators’; remaining 2.3 per cent are workers in ‘household industry’.
