One of the Welsh language strongholds in Powys has seen its number of Welsh speakers drop by 27 per cent in 30 years.

The shocking statistics were revealed within the Welsh language standards report for 2025/2026, which went before a meeting of Powys County Council’s (PCC) Liberal Democrat/Labour cabinet on Tuesday, June 23.

The “Situation of the Welsh Language in South Powys” came from work conducted by the council during the last year.

The council had studied census data on Welsh across Powys to identify trends across the county.

The report said: “This analysis highlighted a significant shift in the Ystradgynlais area, where the proportion of Welsh speakers has declined by 10 percentage points since 2011, with some wards, such as Ynyscedwyn, recording an 11-point decrease.

“When viewed over a longer period, the decline is more pronounced.

“The proportion of Welsh speakers in the Ystradgynlais area has fallen from 61 per cent in 1991 to 34 per cent in 2021, representing one of the largest declines recorded in Wales over that 30-year period.”

Cabinet member for the Welsh language Cllr Sandra Davies (Labour – Cwm-twrch) said: “Unfortunately we have had a decline of Welsh speakers in some areas and I’m sad to say we have seen a significant drop in Ystradgynlais.

“There is a new linguistic mapping study planned to understand and address this so there is work going on to try and resolve these problems.”

Cllr Davies explained that in general the council is: “largely compliant with Welsh language standards”.

Cllr Davies continued: “But needs to improve consistency, coordination and organisational systems with a stronger focus on embedding Welsh in service delivery and decision making.

“Our general compliance is strong, but inconsistency remains in some areas.”

Cabinet member for a more prosperous Powys Cllr Glyn Preston (Liberal Democrat – Llanidloes) said he would endeavour to speak more Welsh in council meetings.

Cabinet member for education Cllr James Gibson-Watt (Liberal Democrat – Glasbury) also highlighted the work the council is doing to create more Welsh medium schools in Powys.

Cllr Gibson-Watt said: “It’s worth noting the work being done by the administration to expand Welsh medium education.

“We have made more significant progress in the last few years than in decades.

“And the development we’ve made will expand the proportion of the population that can speak Welsh and create a more bilingual county.

“That needs to be acknowledged.”

Cabinet went on to approve the report, which will be officially published on the council’s website by the end of the month.
