Equity ratio of insecticide-treated net (ITN) household ownership and use in children under the age of five years, over time ( 2005–2011), mainland Tanzania. ITN household ownership (dashed lines) and ITN use in children under the age of five years (solid lines) are shown for Tanzania mainland (triangles), Southern zone (diamonds) and Lake zone (squares) for the years 2005 to 2011. Coastal zone is not shown because there is only one data point (2011) available. Nationally representative data comes from national household surveys conducted by the monitoring and evaluation contractor. See main text for definition of equity ratios.
