Three parts of Wales remain near the bottom of the GDP league table.
Anglesey has the fourth lowest GDP per head in the whole of the 海角视频 - although it wasn鈥檛 long ago when the island was right at the bottom of the productivity table.
Its GDP figure - a calculation of the value of goods and services produced - for 2018 is 拢17,781, up 3.8 per cent on the previous year.
This was before the shelving of the 拢12bn Wylfa Newydd nuclear plant development.
Gwent Valleys (拢17,908) and Central Valleys (拢17,950) were also in the bottom 10 for the 海角视频.
In the Gwent Valleys the figure has increased by 2.9 per cent over the year while the Central Valley had seen a fall in productivity of 4 per cent.
The Welsh average is 拢23,866 while the 海角视频 figure is 拢31,976.
Cardiff and Vale of Glamorgan had a GDP per head of 拢31,824 - the best performing part of Wales.
Welsh Government said it is committed to bringing prosperity to all parts of Wales.
A Welsh Government spokesman said: 鈥淒espite GDP growth in Wales being 2.3 per cent last year, compared to an increase of just 1.5 per cent for the 海角视频 as a whole, we remain committed to spreading prosperity across Wales as a priority.
鈥淐learly this is difficult as we operate against the challenging backdrop of a decade of 海角视频 Government austerity, but through our Economic Action Plan we are working to grow the Welsh economy at both a national and regional level and to ensure the benefits of sustainable economic growth are felt as widely as possible.鈥
The figures are calculated per head of population and not per worker, meaning areas with higher than average numbers of retired people can appear less productive than others.
The three least productive parts of the 海角视频 were Torbay in Devon (拢17,409), East Ayrshire and North Ayrshire mainland in Scotland (拢16,795) and Ards and North Down in Northern Ireland (拢15,034).
