The Labour Party says only 14 licensed premises in Dublin have been closed since 2000 for serving minors.
The party claims the statistics, which it obtained from the Department of Justice, were proof of the Government's inability to tackle the problem of underage drinking.
Dublin North West Labour TD, Ms Roisin Shortall
Dublin North West TD, Ms Roisín Shortall said the figures show "alarming discrepancies" between the number of pubs and off licences closed down in Dublin and the rest country.
Ms Shortall said: "Dublin is by far the most lenient part of the country, with zero premises being closed down for this offence in 2000, 2001, and 2004, whilst 10 were closed in 2002, and only four in 2003."
"This contrasts with closure rates in the west, where in the same period 113 premises have been shut down for exactly the same offence," she said.
"What is happening in Dublin? Are pubs and off licences not being monitored by the gardaí for the selling alcohol to minors? Have we got to a stage where we have admitted defeat in combating underage drinking?," Ms Shortall asked.
Figures supplied to the Labour TD by the Minister for Justice show that just 27 closure orders against pubs or off-licences were made between January and August this year. Of these, nine were in the south east, two in the south, seven in the eastern region, three in the northern region and six in the western region.
