The Big Question: Why has social mobility declined, and what can be done to reverse the trend?

Why are we talking about social mobility?  

New research confirms the image of Britain as a relatively rigid society. There is proportionately more chance that, if you're born poor in Britain, you'll stay poor.

Academics, supported by the Sutton Trust, an educational charity, have been following the changing fortunes of samples of children born in 1958 and in 1970. The group born earlier are doing relatively better in terms of "life chances": "Early indications are that the decline in social mobility for those growing up between the 1970s and 1980s reflects a strong episode of worsening social mobility that was not seen before or since. The trend of worsening has stopped, but the UK remains very low in the developed-world rankings and faces a serious challenge if social mobility is to be promoted."

Gordon Brown has made opportunity one of his themes, declaring in his leadership speech that: "Wherever we find opportunity denied, aspirations unfulfilled, potential unrealised; wherever and whenever we find injustice and unfairness, there we must be also - and it is our duty to act."

In the 1980s, the Conservatives were the party of social mobility; from Essex Man buying his council house and shares in the privatised utilities to the yuppies in the City. The Conservatives have recently become interested in the upwardly mobile again. They controversially changed their policy on grammar schools because they doubted their contribution to mobility. According to front bencher David Willetts, "stark figures" about declining mobility "have exposed our complacent belief that British society is inexorably becoming more socially mobile ... our schools are entrenching social advantage".

Both Tony Blair and the former Conservative prime minister, Michael Howard, talked about a "British dream", a version of the American dream, where a baby born in a log cabin can make it to the White House. The fact that the Conservative leader, David Cameron, is an Old Etonian, and has become popularly thought of as being fond of "hugging hoodies", has also prompted more interest in the issue.

What is social mobility?

Social mobility is the extent to which a child's social status can alter through the course of their life. It also relates to how easy it is for a child born to parents in one social class to wind up in another class. Social mobility, however, can exist side by side with vast differences in wealth (indeed, some claim such disparities amount to an incentive for the diasadvantaged). A society with equality of opportunity can be one where there is little "equality of outcome". In reality, societies that are less unequal in the first place tend to have fewer opportunities for individuals to leap class barriers.

How unequal are we?

In terms of income and wealth, we're more unequal than for decades, with the very rich (average incomes in excess of £500,000) now pulling further away from the merely prosperous. In terms of equality of opportunity, if you were born in 1970 into the poorest quarter of the population, there's a 37 per cent chance you'll be staying there; for those born in 1958, there was only a 31 per cent chance of remaining in that stratum. But ...

Are we becoming more unequal?

Yes and no. We're no longer feudal, after all; the age of deference has long gone; women and ethnic minorities enjoy legal protections and there is, probably, less snobbery and prejudice around than before the Second World War. Sociologists have found that there has previously been little "long-range" mobility in Britain for people born between 1900 and 1960.

An Oxford University study reported that then only about 10 per cent of boys from working-class backgrounds ended up in the professional classes. Post-Second World War, the rise of the "meritocracy", much hyped in the 1960s, appears to have stalled. Although there was a decline in mobility between those born in 1958 and those born in 1970, matters did not get worse for children born through the rest of the 1970s and 1980s: "it appears that the downward trend in social mobility has halted."

Even so, while for those born in the early 1980s the gap narrowed between those staying on in education at age 16, inequality of access to university education has widened further. The proportion of people from the poorest fifth of families obtaining a degree has increased from 6 per cent to 9 per cent, but the graduation rates for the richest fifth have risen from 20 per cent to 47 per cent.

Measures such as SureStart, reforms in schools and child tax credits might have improved mobility since 1997, but it's too early to tell. Differences in life chances for people from different ethnic origins, reflected in their very different representation in the various social groups, persist strongly.

Immigrants to the UK have historically been downwardly mobile. Many first-generation Commonwealth migrants during the 20th century were forced to take manual jobs in the UK, having held white-collar positions in their country of birth. So most minority ethnic groups show high levels of children moving into a higher class than their parents, consistent with the idea that their parents suffered downward mobility on arrival in Britain.

Ethnic minorities are more likely to be socially mobile (in both directions) than the white population. Whereas 57 per cent of the white population were found not to be mobile in a census study, this dropped to 42 per cent for those of Indian origin and 37 per cent for Pakistanis, both groups seeing broadly equal rates of upward and downward mobility.

How does Britain compare internationally?

The Sutton Trust researchers found that the UK is bottom of the table of advanced countries for which there is data. Although the gap in opportunities between the rich and poor is similar in Britain and the US, in Britain those gaps are getting wider.

Does money matter?

Yes, but not as much as some might think. According to the Sutton Trust researchers, "While it is clear that family income differences between the rich and the poor do have a big impact on children's educational outcome, the estimated impact of income is modest relative to the large differences in attainment between children from richer and poorer families. Consequently, while reducing child poverty can have some benefits, policies to increase intergenerational mobility will need to focus on raising poorer children's attainment through targeted services and access to the best schools.

So what's the key to social mobility?

Education would seem to be the consensual answer, although there is huge disagreement on whether structures, standards or spending make the difference. The Sutton Trust study states: "The strength of the relationship between educational attainment and family income, especially for access to higher education, is at the heart of Britain's low mobility culture and what sets us apart from other European and North American countries."

Common sense tell us that if the poorest children in the worst housing are sent to the worst schools then they're unlikely to prosper. On that, the academics and politicians seem to agree.

Is Britain becoming a more rigid society?

Yes...

* The most recent research confirms that life chances are worse for people born in 1970 compared with those born in 1958

* The boom in university education has mostly benefited the well-off

* Ethnic origin can still have a profound effect on mobility

No...

* The age of deference is dead. If you want to make a fortune, there's never been a better time

* Test results suggest that the worst schools may be improving faster than the average

* More people are staying on at school after 16 than ever before
