  • The 20 fastest-growing freelance skills experienced more than 130% year-over-year growth in demand. — Upwork, 2018

Freelance work has exploded in recent years, thanks to talent shortages faced by many enterprises and the rise of the gig economy. More than half (53%) of hiring managers cite access to skills as their biggest hiring challenge, and the majority (59%) are already tapping flexible talent, according to a recent report from freelancing website Upwork.

“As skills become more specialized, companies either need to invest in reskilling to prepare workers for the jobs of tomorrow or leverage freelance professionals who are nearly twice as likely as traditional employees to proactively take reskilling upon themselves,” Stephane Kasriel, CEO of Upwork and co-chair of the World Economic Forum’s Council on the Future of Gender, Education and Work, said in a press release. “Many of today’s Fortune 500 companies are already doing this, and adoption of flexible workers will increase as hiring gets harder.”

But what skills are most in-demand when it comes to freelance work? On Tuesday, Upwork released its Q1 2018 Skills Index, ranking the 20 fastest-growing skills for freelancers. The 20 fastest-growing freelance skills experienced more than 130% year-over-year growth in demand, the report found. Demand for the top 10 skills grew more than 400% compared to the same time last year.
