There is a clear link between levels of social deprivation, health inequalities and corresponding increases in mental health problems (Acheson 1998). In this context, key specific areas in Tendring stand out as experiencing high levels of deprivation in one form or another. In calculating area level deprivation, the Index of Multiple Deprivation (IMD) is the main indicator of deprivation. The most recent assessment of these indices was completed in 2007. However, many reports still draw on the previous index, which was compiled in 2004 (see, for example, the Joint Strategic Needs Assessment (JSNA) - Tendring Profile 2008). This report will draw from the most recent available data whenever possible, but will also draw from older data when necessary.
