50% in 1901 to 43.5% in 1911 and continued to fall to a low of 18.9% in 1981. 21st century In the 2011 census, it was recorded that the proportion of people able to speak Welsh had dropped from 20.8% to 19% (still higher than 1991). Despite an increase in the overall size of the Welsh population this still meant that the number of Welsh speakers in Wales dropped from 582,000 in 2001 to 562,000 in 2011. However, this figure was still much higher than 508,000 or 18.7% of people who said they could speak Welsh in the 1991 census. The Annual Population Survey of April 2020 to March 2021 reported that 29.1% of people aged three and over were able to speak Welsh which equates to 883,300 people. For October 2020 to 30 September 2021, the Annual Population Survey showed that 29.5% of people aged three or older were able to speak Welsh which equates to approximately 892,500 people.

Following a successful referendum in 2011 on extending the law-making powers of the National Assembly, it was then able to make laws, known as Acts of the Assembly, on all matters in devolved subject areas, without needing the UK Parliament's agreement. In the same year, the International Standards Organisation agreed to apply the description of "country" to Wales in its technical publications, following lobbying from Plaid Cymru AM at the time, Leanne Wood. In the 2016 referendum, a majority of Welsh voters supported leaving the European Union, although there were regional differences. According to Danny Dorling, professor of geography at the Oxford University, “If you look at the more genuinely Welsh areas, especially the Welsh-speaking ones, they did not want to leave the EU.” In May 2020, the National Assembly for Wales was renamed "Senedd Cymru" or "the Welsh Parliament", commonly known as the "Senedd" in both English and Welsh. The results of the 2001 Census showed an increase in the number of Welsh speakers to 21% of the population aged 3 and older, compared with 18.7% in 1991 and 19.0% in 1981.
