More than 5.2 million people have not reported crimes for fear of deterring home-buyers or renters since the Home Office's online crime map was launched in February 2011, according to research from insurers Direct Line.
An online poll of 2,685 adults conducted on behalf of the insurance company found that of the people not reporting crimes, nearly 75 per cent had ignored antisocial behaviour such as drug-dealing or vandalism for fear of devaluing the neighbourhood.
