Leading article: Happy days

Is there anything so relentlessly pursued and yet so badly defined as happiness? The Halifax bank carried out a survey two years ago to find Britain's happiest locality. Using criteria such as employment levels, house prices and salaries, it identified Elmbridge in Surrey as the most blissful enclave in the land.

Now the British Household Panel Survey has tried the same thing. In this case, though, they asked residents questions about their "subjective wellbeing" such as whether they get uninterrupted sleep at night and whether they feel confident in their daily lives. This study has named Powys as the most contented area.
