A study carried out by the CBRE Ireland Research Team in 2012 found that 16% of retail units on O'Connell Street were vacant, making it the worst performing main city thoroughfare in Ireland in retail terms. The results also reflected poorly on the quality of retail offered on O'Connell Street with Limerick having the greatest proportion of fast food restaurants on its main street, at 21%, followed by footwear at 13%, and jewellery stores at 5%; this was in stark contrast to other Irish cities and towns where women's fashionwear occupies the core retail slots on the main streets and also offer a more mixed fashion offering.
