The latest homeless figures show a slight drop in the number of adults and families in emergency accommodation.
However, Minister for Housing Eoghan Murphy has said previous figures have been overstated by around 600 people.
The latest figures for March show that there are 126 fewer people in emergency accommodation around the country, including 17 adults, 19 families and 109 children.
The current total number of homeless people is recorded as 9,681, which is down from 9,807 in February.
In Dublin, the number of homeless families has remained the same at 1,329.
Minister Murphy has said that some local authorities had previously overstated the numbers of homeless by including some people in local authority housing or renting in the private sector and in receipt of social housing supports.

"To date at least 600 individuals have been identified as having been categorised as homeless and in emergency accommodation when they are not," he said.
"Some, but not all, of these individuals have been removed from the total numbers, but work continues with local authorities to gauge the total extent of the issue."
Minister Murphy said that the current reporting system needs to be reformed.
It is not known how much previous overstatement of numbers has affected these figures.
The Dublin Region Homeless Executive has reported that new presentations by families in need of emergency accommodation are down from 261 in February to 135 in March.
However, the housing group Inner City Helping Homeless has said it has seen an increase in families presenting themselves at Dublin garda stations in recent weeks.
