Mae'r Concordat ar Ystadegau yn nodi'r fframwaith y cytunwyd arno ar gyfer cydweithredu, cydweithio a sicrhau consensws mewn perthynas â llunio ystadegau, safonau ystadegol a'r proffesiwn ystadegau.
The Concordat on Statistics sets out the agreed framework for co-operation, collaboration and consensus in relation to the production of statistics, statistical standards and the statistics profession.
