Almost one in every three children has been deprived of food, heating or clothing during the recession.
The ESRI has released new research on the impact of the downturn on different age groups, genders and family types over the past five years.
The ESRI report, From Boom to Recession, finds that younger people have been the worst affected, with unemployment rates hitting 25% in the under 25s category, compared to 12% for those aged 45 and over.

The gender gap between men and women in work fell from 16% in 2007 to 8% in 2012 - while one in 10 women are now the main breadwinners in their household.
