My Department does not collect specific statistical information on the estimated number of overcrowded households, as sought by the Deputy.
Housing statistics that are collected by my Department can be accessed on my Department's website at the following link:
http://www.housing.gov.ie/housing/statistics/housing-statistics.
However, the annual statutory Summary of Social Housing Assessments (SSHA) does collate information on the number of households qualified for social housing support in each local authority area. Table 2.5 and Table A1.5 of the summary ‘Main Need for social housing support’ reports on the number of households that are qualified for and in need of social housing support due to their current accommodation being overcrowded. The most recent SSHA for which data has been published was conducted on 24 June 2019 and the results are available on my Department’s website at the link below:

It should be noted that due to the Covid 19 pandemic, the 2020 assessment was delayed and has only recently been conducted. The summary of the 2020 assessment will be published in due course.
