There are similar problems with city definitions in Ireland. In 2002, the population of the Cork Urban Area was 186,239 (CSO figures), yet the population of the city council area was 123,062.
Limerick Urban Area had a population of 86,998, while the population of the city council area was 54,023.
A look at the figures suggests Galway has surpassed Limerick as Ireland's 3rd largest city with a population of 65,832. However, Galway's boundaries pretty much fit the city and it has an overall population of 66,163.
