This set of results cover the period from July 2023 to June 2024, meaning that some responses were collected through face-to-face interviews and others over the phone.
Mae'r canlyniadau hyn yn cwmpasu'r cyfnod rhwng mis Gorffennaf 2023 a Mehefin 2024, felly casglwyd rhai o’r ymatebion drwy gyfweliadau wyneb-yn-wyneb ac eraill dros y ffôn.
