Official homeless reports are published on my Department's website on a monthly basis and can be accessed using the following link:
http://www.housing.gov.ie/housing/homelessness/other/homelessness-data.
These monthly reports include a breakdown based on accommodation type. Commercial hotels are included within the private emergency accommodation (PEA) category as are other commercially provided emergency accommodation arrangements. The Dublin Region Homeless Executive publishes specific information on the numbers of families in hotels in the Dublin region on its website, at www.homelessdublin.ie/reports.
