This set of results cover the period from January to December 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 Ionawr a Rhagfyr 2024, felly casglwyd rhai o’r ymatebion drwy gyfweliadau wyneb yn wyneb ac eraill dros y ffôn.
