More than half of Irish pubs have failed to attract new customers and more than half have lost revenue for the year, according to a survey commissioned by the Irish Times.
More than a quarter of pubs, including pubs with over 50,000 pub patrons, have not made money since 2015, according the study.
A total of 10 pubs have closed in the past year, with most closing within a year.
Only three pubs in a dozen have made a profit for the past 12 months.
The report found that in 2016/17 the average pub in Ireland lost almost £6,000 per pub patron, with losses rising by more than 25 per cent in 2017/18.
There are more than 1,000 pubs in Ireland.
Most are small pubs that have been around for years and have only one or two customers, with one or less people in their staff.
A number of pubs have been forced to close, including those with more than 50,00 patrons and those with fewer than 50 patrons.
However, the number of people patronising the pubs has remained stable over the last few years, and in some cases, increased by more.
The survey found that, over the past three years, the average number of patrons in the pubs decreased by 1.5 per cent and the average amount of beer consumed by customers decreased by 0.7 per cent.
The number of customers in the pub increased by 4 per cent between 2016/2017 and 2017/2018.
The average size of the pub decreased by 9.1 per cent during the same period.
The majority of pubs in 2017 had fewer than 20 people in the staff.
The rate of change for the number in the bar decreased from 2.5 to 1.9 per cent, while the number out front increased from 7.3 to 9.5.
While the number on the bar increased, the rate of turnover decreased from 1.3 per cent to 1 per cent over the same time period.
There were a total of 9,836 pubs in Dublin in 2017.
