However in a sign of the times, new data from the company shows that one in every ten of those now work abroad.

LinkedIn, which employs 400 people here, currently has 259 million members around the globe.

According to the social network's Irish membership data, the biggest sector of employment of its users is the tech industry, with the HSE the most cited employer, and UCD the university that's most often listed by members as the place they studied.

Of the 100,000 Irish members of LinkedIn who live and work abroad, half are in Europe.
