Mr. Chris Macey:

The rate of deaths from CVD in the lower socioeconomic areas is two to three times higher than the rate in the highest. Things like air pollution, which is more prevalent in inner cities, have a much greater effect in areas of socioeconomic disadvantage than in the more salubrious areas where people might live. Likewise, smoking rates are higher and, when looking at what is sold in different supermarkets and where fast food outlets are located, it can be seen that unhealthy food and drinks tend to be more prevalent in disadvantaged areas.
