The Irish Albums Chart is the Irish music industry standard albums popularity chart issued weekly by the Irish Recorded Music Association and compiled on its behalf by Chart-Track. Chart rankings are based on sales, which are compiled through over-the-counter retail data captured electronically each day from retailers' Point of sale systems and certain digital retailers. All major record stores and over forty independents submit data for the charts, accounting for over 80% of the market, according to Chart-Track. A new chart is compiled and released to the public by the Irish Recorded Music Association on Friday at noon. Each chart is dated with the "week-ending" date of the previous Thursday (i.e., the day before issue).
It is released as a Top 100; however, Chart-Track's records only record the Top 75 in the archives.
