The informal labour market is a very large part of the agricultural sector, but is also a significant part of the urban sector. There is a difference between employment in the formal sector and the informal sector in terms of conditions of work, whether workers are subject to government taxes, have access to social security or insurance, casual or contract workers. The NSSO (2012, p ii) document finds that in 2009-2010 in the non-agriculture sector, nearly 71 percent of the workers in rural areas and 67 percent in the urban areas worked in the informal sector. It finds that the informal sector activities are concentrated mainly in the manufacturing, construction, wholesale and retail trades, and transport, storage and communication industries.
