A 2009 all-India survey finds that 71% of Indian households have access to adequately iodized salt and nearly 20% more use salt with some, but inadequate amounts, of iodine. This represents a sharp increase from a similar survey in 2006 when only 54% of households had access to quality iodized salt.

Urban households had higher access to quality iodized salt; 83.2% versus 66.1 in rural households. Use of iodized salt was high in northeastern India and lower in the south, even in salt producing centers like Tamil Nadu.
