The Glasgow Effect is the low life expectancy and poor health of people living in the area. Poor health is often related to low levels of income. A study shows that the most deprived areas of Glasgow, Manchester and Liverpool are very similar, however in Glasgow, premature deaths are 30% higher. The life expectancy of men in Glasgow is almost 7 years below the national average and for woman it is 4 years below. alcohol consumption, smoking and obesity are all factors leading to poor health which is why the mortality rate is lower.
