There have been calls for changes to garda recruitment after figures revealed that 71 gardaí resigned from the force so far this year.
Figures accurate to the end of June also show a further 172 retired in the first six months of the year.
Fianna Fáil TD Jim O'Callaghan has called for the policy of mandatory retirement at the age of 60 to be reconsidered.
Mr O'Callaghan also wants a change in policy to allow recruits over the age of 35.
Speaking to RTÉ News, he said: "I think the Government needs to look again at the prohibition that we have in terms of recruiting gardaí over the age of 35. And also, we need to look at the retirement age.
"There are very many fine gardaí who are forced to retire at 60. If we increase the retirement age, we'll be able to keep more in the force.
"It's a short-term measure that Government should be looking at, because we really need to try and get the numbers back above 14,000.
"One way of trying to do that would be to ensure that gardaí don't have to retire at the age of 60. Give them the option of staying in the force until they're 62 or 63.
"It's not the only answer, but it's a significant answer and that's an important part of the solution."
The numbers are published just days after Minister for Justice Helen McEntee admitted that garda recruitment was not where the Government wanted it to be, saying she wished they were further ahead.
In a statement, the Department of Justice said a review of the garda retirement age is already under way.
Garda sergeants and inspectors are among those who have also called for the age to be increased above 60.
The data, which is based on figures compiled by the Garda Commissioner for a monthly report to the Policing Authority, also shows a problem on garda numbers is looming in the next ten years.
Almost 2,500 gardaí will retire from the force between now and 2033 based on years of service alone.
Policing and safety on the streets has become something of a political headache for the Government after a series of violent incidents in Dublin city centre brought the issue of garda recruitment into sharp focus.
Minister McEntee last week announced €10m in additional funding specifically targeted at increasing garda visibility in Dublin.
The money will provide for 240,000 extra garda hours, or 20,000 extra garda shifts, putting more gardaí on the streets in the capital until the end of year.
