Food security is separate from food bank usage and is derived from information on a household’s access, attitude and behaviour around food over the last 30 days.
Mae diogelwch bwyd yn rhywbeth ar wahân i ddefnydd banciau bwyd ac mae'n deillio o wybodaeth am fynediad, agwedd ac ymddygiad y cartref tuag at fwyd dros y 30 diwrnod diwethaf.
