Sustainable elimination of iodine deficiency disorders by 2005.
UNICEF estimates that 75 per cent of all households globally have adequately iodized salt. East Asia and the Pacific is the only region close to attaining the universal salt iodization (USI) target of 90 per cent. At the other end of the spectrum, about half of all households in sub-Saharan Africa and least developed countries have adequately iodized salt in households, indicating that the greatest need for enhanced efforts is in these places.
More than one quarter of all countries in Central and Eastern Europe/Commonwealth of Independent States (CEE/CIS) have achieved the USI target of 90 per cent, but data for overall regional coverage are not available due to lack of recent estimates from the Russian Federation, the most populous country in the region.

In more than half of the 50 countries with recent estimates by household wealth information, use of adequately iodized salt was more common among the richest 20 per cent of households than the poorest 20 per cent. In 55 of 62 countries where residence information was available, consumption of iodized salt was more common in urban households than in rural households. Further attention is needed to identify and address barriers to the equitable use of adequately iodized salt in affected communities.
Iodized salt consumption is higher among the richest households than the poorest households in countries with available data
Percentage of households consuming adequately iodized salt among the richest 20 per cent of households as compared to the poorest 20 per cent, by country, 2006–2011
Note: Based on 44 countries with available disparity data. Each circle represents data from one country. The size of a circle is proportional to the size of the country's population. The horizontal axis represents the percentage of the poorest 20 per cent of households consuming adequately iodized salt, while the vertical axis represents the percentage of the richest 20 per cent of households. Circles along the green line represent countries in which the likelihood of consuming adequately iodized salt is similar among the richest and the poorest households. Circles above or below the green line suggest disparity. The closeness of circles to the upper-left corner indicates greater advantage for the richest households in that country (greater disadvantage for the poorest households).
