We have introduced a new question in the survey during 2023 that captures household income that will be used to analyse and report on trips taken by different household income bands from 2023 onwards.
Fe ddechreuom gasglu’r data yn ystod haf 2023, a hynny trwy gyflwyno cwestiwn newydd ar y ffurflen dreth Treth Trafodiadau Tir.
