For more than 200 years the city has welcomed workers from across the globe. Today, the city is home to over a hundred different nationalities with a broad range of language skills. Companies based in the Capital Region report a good experience in recruiting multi-lingual workers. 

Cardiff has a very diverse population with a history of trade connections, post-war immigration and international students who attend university. Adding to the city’s rich diversity, Cardiff is home to two Cathedrals (Llandaff Cathedral and St David’s Catholic Cathedral), many mosques, synagogues, and temples welcoming people of all faiths. 

There is also a Muslim population of about 4%, which is well above the Welsh average and the UK average of 2.7%. Interestingly, Cardiff has the smallest percentage of people over 65 living in Wales at 13% which gives it a younger mobile workforce than other areas. 

A growing, thriving and creative city

Cardiff is a member of the Core Cities UK, an alliance made up of 11 cities (consisting of Belfast, Birmingham, Bristol, Cardiff, Glasgow, Leeds, Liverpool, Manchester, Newcastle, Nottingham and Sheffield). Its mission is to unlock the full potential of our great city regions to create a stronger, fairer economy and society. It’s the fastest-growing UK Core City and its wider Capital Region with a population of 1.5 million is projected to grow by more than 20% over the next 20 years. The Cardiff-Newport metropolitan area has a population of 1.1 million.

The city’s growth is supported by its world-class universities and highly-qualified graduate workforce, great connections with the rest of the UK and Europe, and a business community that includes major companies, entrepreneurs and innovators who are amongst the best in the world.

The heavy industry of the past has given way to flourishing service and knowledge-driven sectors. The city’s recent development has seen internationally competitive clusters emerge in the financial, creative, life sciences and advanced manufacturing sectors, with some of the UK’s leading businesses in these sectors calling Cardiff home. 

The growth of the city’s creative and digital sector is also driving the city’s resurgence. Cardiff places culture, creativity, and innovation front and centre because the city believes that the challenges it faces will be best met with creative solutions.

Cardiff is benefitting from continued investment in the city infrastructure, including a £1bn investment in a South Wales Metro which will see more frequent, more reliable, and faster trains accessing nearly 100 stations across a network that has Cardiff as its core. Cardiff is a major centre for television and film production (home to Dr Who, Sherlock and Torchwood) and is the Welsh base for the main national broadcasters.

Quality of life is a big pull when attracting businesses to Cardiff. Residents consistently rank the city as one of the best European cities to live in. Befitting a capital city, Cardiff is home to world-class sporting and cultural institutions and has a growing reputation as a first-class destination for leisure, culture, retail and business, hosting the 2017 UEFA Champions League Final, Rugby World Cup, FA Cup Finals, IAAF World Marathon, Volvo Ocean Race, a NATO Summit and world-renowned artists such as Beyonce and Harry Styles.
