Britons are no more satisfied with their lives than they were before the financial crash, new figures show.

When asked to rate their quality of life out of 10, UK residents give an average score of 6.8 - the same as in 2007.

The figure suggests Britons are more satisfied with their lives than people in Italy (6.0) and Portugal (5.1), but not as content as residents of Norway (7.4) or Australia (7.3).

Among all the 34 members of the Organisation for Economic Co-operation and Development (OECD), Greece has the lowest life satisfaction score (4.8) while Denmark, Iceland and Switzerland have the highest (7.4).

The UK's score is slightly above the OECD average of 6.6 points.

The figures are among a collection of information on wellbeing from the Office for National Statistics, which compares a range of recently-published data for the UK with other countries around the world.

Britain fares particularly well when measuring personal satisfaction. The proportion of people saying they are completely, very or fairly happy with their life stands at 87.2%, just below the top-ranking score of 92.4% for Iceland.

The lowest country in this category is South Korea, which scored 62.6%.

The UK emerges even stronger when measuring domestic happiness. Nine out of 10 people (90.9%) say they are completely, very or fairly satisfied with their family life - the fourth highest score in the OECD, below only Iceland, Switzerland and Mexico.

South Korea is once again at the bottom of this category, with just 65.3%.

Britain scores slightly less well when measuring health, however.

Roughly three out of four people (74%) describe themselves in good or better health. This ranks eight percentage points below the UK's nearest neighbour Ireland (82%) and even further behind the likes of the US (88%) and New Zealand (90%), though above the OECD average of 68%. The lowest score among OECD countries is Japan, where under one in three people (30%) are in good health.

Other data in the report suggests that Norway is the country where people feel safest walking alone at night in a city or the area in which they live, and that Sweden is the country whose households have the least difficult in making ends meet. Greece achieved the worst score in both these categories.

Commenting on the data on wellbeing, Ruth Sutherland, chief executive of leading relationships charity Relate, said: "We know that there is a strong connection between our relationships and our personal wellbeing: relationships act as shock absorbers when times are hard and also help us to achieve our goals. Family relationships are an important part of this picture, so it is good news that today's ONS data shows 91% of people in Great Britain reported being satisfied with their family life in 2012."
