You may find Jaideep Gupte's "three steps" helpful, but for me the most interesting part of his posting were these background data:
… here are some basic statistics to help you make up your own mind: unemployment in the UK for 16-24 years olds is up from 17.90% in the early 1990s to 19.70% in 2010, while London continues to have the highest unemployment rate for this cohort at 22%. Currently, 22% of 19 year old boys in England do not have a basic education, while this figure drops to 15% for girls. Black young adults (16-24 years) are four times as likely to be in prison under sentence, than White young adults, and almost eight times as likely as Asian young adults. Nevertheless, the number of burglaries and violent incidents with injuries have dropped significantly since the 1990s – from 1.8 million burglaries in 1995 to 0.7 million this year, and from 2.4 million incidents to 1.2 million over the same time period. 50% of adults surveyed in 2000 believed that the crime rate was increasing, this figure has dropped to 28% now. And while 24% of adults reported being very worried about being the victim of violent crime in 2000, this year the figure has dropped to 13%.
