Hello,
Earlier this year Wikimedia UK conducted a survey of Welch Wicipedia's readers. We wanted to learn more about their demographics and why they chose to read Welsh Wicipedia. 1001 people filled in the survey and the results are available on meta-wiki in English https://meta.wikimedia.org/wiki/Research:Readership_of_Welsh_Wicipedia and Welsh https://meta.wikimedia.org/wiki/Research:Canlyniadau_arolwg_o_ddarllenwyr_Wicipedia_Cymraeg .
