This week we have added additional analysis by local authority, gender, year group, free school meal eligibility and reason for absence.
Yr wythnos hon rydym wedi ychwanegu dadansoddiad ychwanegol fesul awdurdod lleol, rhyw, grŵp blwyddyn, cymwys i gael prydau ysgol am ddim a’r rheswm dros absenoldeb.
