More than 19,000 people are still living in ghost estates across Ireland.
Figures from the Department of the Environment show that there are still nearly 500 occupied developments in Ireland.
The department's fourth annual progress report on unfinished housing developments also showed a 75pc drop in unfinished developments since 2010, from almost 3,000 to 668 in 2015.
Of the 668 unfinished developments, 492 are occupied. County Cork had the highest number, with 73 unfinished sites occupied. Some 34 undeveloped sites were in Kerry while 33 were in Tipperary.
Housing Minister Paudie Coffey (pictured) said the report was "good news" and claimed the reduction represented an effort "to clean up the mess left by Fianna Fáil".
But he stressed that some local authorities needed to do more to reduce the number of unfinished developments in their areas.
"We estimate that there are quite a number of housing estates around the country that local authorities still haven't taken charge of," he said.
