WCFI&ES scheme is intended to conduct survey of Income and Expenditure and House Rent of industrial workers at the selected industrially important centres of the country. The main purpose of this survey is to compile the weighting diagrams of Consumer Price Index for Industrial workers (CPIIW)). The CPI-IW is utilised for fixing/revising wages, regulating the dearness allowances paid to thousands of skilled workers and other Central/ State Govt. employees. Earlier, on the request of Labour Bureau, FOD conducted this Survey for current series of CPI-IW with base 2001=100 during September 1999 to August 2000. The Labour Bureau has decided to conduct a fresh Working Class Family Income And Expenditure Survey (WCFI&ES) at 88 centres of various States/UTs spread all over India for changing year of CPI (IW) to 2015=100. The existing series of CPI-IW with base year 2001=100 covers the workers belonging to seven sectors, namely, Factories, Mines, Plantation, Railways, Public Transport, Undertakings, Electricity Generating & Distributing Establishments and Ports and Docks at 78 selected centres covering 57,000 schedules. The new series is proposed to cover 88 selected centres covering 67,200 schedules on earlier seven sectors along with coverage of two additional sectors viz. Construction and Handloom on pilot/experimental basis. Two centres each from Construction and Handloom sector shall be covered separately and shall not be part of All India series.
