Youth unemployment up 14pc in 3 years

But the research by the Office for National Statistics showed the rise in the unemployment proportion for people aged 16-24 was more modest, from 9.4% to 12.8%, or about a third up.

Unemployment as a proportion of all 16 to 24-year-olds rose during the recession of 2008-09, but less sharply than the rise in the youth unemployment rate, which measures unemployment as a percentage of the economically active population.

During the 2008-09 recession, the rise in the proportion of young people who were unemployed was coupled with a rise in the proportion who were inactive.

This meant that there was a large drop in the proportion who were employed, leading to a sharp rise in the unemployment rate.

For people aged 16-24, both the unemployment rate and the unemployment proportion (that is, unemployment as a percentage of total population of that age group) fell steadily after the peak in 1992-1993, before levelling out between 2001 and 2004.

Both measures then increased slightly between 2005 and 2007 before rising sharply in 2008.

The ONS said the main driver for the increase in inactivity for younger people since 1992 has been their participation in full-time education.

The percentage of 16 to 17-year-olds who were inactive and in full-time education hovered around 40% in the early to mid 1990s.

It dropped slightly between 1995 and 1997 but has been on the increase since 1997.

It rose more sharply during the 2008-09 recession. The percentage of 18 to 24-year-olds who were inactive and in full-time education has been increasing steadily since 1992.
