The diversity report by the Law Society also found that slightly over one in ten (11%) of the country's solicitors in 2015 were eligible for free school meals while growing up.
The profession is also edging towards a balanced male-female split, with women now accounting for 49% of England and Wales' solicitors. Those from black and minority ethnic (BAME) backgrounds made up 14% of the profession, which the Society pointed out was close to the make-up of the wider population.
However, the Society was disappointed to note those with a disability were still sorely underrepresented in the ranks of the legal eagles, accounting for just 6% of professionals. The report also highlighted that just 29% of partners were women, while just 11% were from a BAME background.
Figures released last year by the Sutton Trust and PRIME cast doubt on social mobility in the legal profession, revealing around a third (32%) of partners at firms and three-quarters of top judges had been privately educated, compared with just seven per cent of the general population.
