Housing authorities report to my Department on a monthly basis regarding the number of individuals utilising emergency accommodation arrangements that are overseen by housing authorities. This data is compiled into official homeless reports which are published on my Department's website and can be accessed using the following link:
http://www.housing.gov.ie/housing/homelessness/other/homelessness-data.
These reports include a breakdown of homeless adults accommodated in emergency arrangements on a regional and county basis. A breakdown of the homeless population at a more detailed geographical level is not available from my Department and is a matter for the relevant housing authority.
