The number of people working in Dublin has hit a record high, leading to concerns about pressure on transport and housing in the city.
The latest CSO figures show almost 2.3 million people now at work in Ireland.
Unemployment has fallen by more than 12% this year, while employment has increased by 3%.
To compare, employment in the UK has only increased by 1% this year.
The figures show that, compared to this time last year, an extra 33,000 people are going to work in Dublin every day.
Chief Economist with KBC Bank Austin Hughes is concerned the economy is improving too quickly.
He said the current pace of jobs growth is "undoubtedly" putting pressure on public transport services and the rental housing market.
According to the CSO figures, Dublin generated half of all new jobs in the last 12 months.
The rate of employment growth in Dublin is two thirds higher in than the figure for the State as a whole.
Employment in Dublin grew by 5% in the past 12 months, while it grew by 3% in the State overall.
Dublin Chamber CEO Mary Rose Burke said the figures prove that "we need to get serious about infrastructure investment".
"On the transport side, this means delivering projects such as MetroLink and the DART Expansion programme, as well as rolling out BusConnects and investing in better cycling infrastructure", she said.
Dublin Chamber is also calling for more money to be spent on water infrastructure and housing, to make sure workers have an affordable place to live.
