The data here is not comparable with the data published during the pandemic for 2020/21 and 2021/22, except for Table 7 which has been calculated on the same basis.
Nid oes modd cymharu’r data yma â’r data a gyhoeddwyd yn ystod y pandemig ar gyfer 2020/21 a 2021/22, ac eithrio Tabl 7 sydd wedi'i gyfrifo ar yr un sail.
