The number of second-hand homes advertised for sale on a leading property listings website last month was half of what it was in the same month a decade ago.
There were 12,477 such properties available on MyHome.ie in July, around 50% of the 24,750 listed in July 2014.
MyHome.ie is one of the most popular places in Ireland for those selling a home to advertise, although it is not the only property listings website in the country.
Some homes also change hands without ever being listed on such websites, so the MyHome data cannot be considered the complete picture.
However, the figures do serve to further underline the supply difficulties facing the property market here, one of a number of factors that is driving prices up.
The CSO's Residential Property Price Index rose by 8.2% in the 12 months to the end of May, compared to 7.9% in the year to the end of April - the ninth consecutive month of annual house price growth and the highest rate of increase since November of 2022.
"This analysis highlights the scale of the shortfall in second-hand properties in the last decade and emphasises the work that needs to be done to address the imbalance between supply and demand in the market," said Joanne Geary, Managing Director of MyHome.ie.

"This trend is particularly concerning when one considers that, according to the CSO, the population of the country has grown by an average of 65,000 every year since 2016."
Over the course of the ten years, there has been a 61% decline in availability in Munster, a 59% drop in Connacht plus the three border counties and a 36% decline in Leinster.
MyHome said that in Dublin there has been a 19% drop in second-hand properties for sale since 2014.
In July 2014, second hand homes in Dublin represented 16% of all national stock advertised on the platform, but last month that was 26%, underlining the severe shortage in properties available outside the capital.
7,983 of the homes listed last month had an asking price of €450,000 or below, with 2,893 listed for between €450,000 and €800,000.
"Ireland is experiencing strong economic tailwinds and full employment at present, with a significant increase in high earners recorded recently," said Joanne Geary.
"Added to that, looser lending rules and demand-led Government initiatives such as the First Home Scheme and Help-to-Buy Scheme have also strengthened demand.
"There is a vicious circle in the market at present, whereby those looking to trade up or down appear to have been spooked by the lack of stock available and are delaying a sale as a result, leading to an overall and consistent reduction in supply."
