Unemployment in the Fourth Plan Some Estimates K L Bagal THE Fourth Plan, ostensibly on the advice of the Committee of Experts on Unemployment (known as the Dant- wala Committee), refrained from giv- ing any estimate of the back-log of unemployment. The Planning Commission's decision to block whatever crude information on unemployment that was so far available through the Plan documents was questionable, even after conceding that the presence of self-employment and under-employ- tnent in a predominantly agricultural society does make a simple uni-dimen- sional definition of unemployment rather difficult. Nevertheless, in the absence of refined data, the cruder unemployment estimates furnished by the Planning Commission were serving a useful purpose of highlighting the magnitude of the unemployment problem.
