Remote work is becoming the new normal, thanks to the right mix of employee demand for work-life balance and companies investing in resources that enable a work-from-anywhere arrangement.

Of course, not all jobs lend themselves to a fully remote work experience, and people with certain skill sets may find it easier to make the leap to the flexible working world. A report from teleconferencing company Owl Labs found that the industries with the highest shares of remote workers include health care, technology/internet, financial services, education and manufacturing. By department, remote workers are more likely to be in facilities and operations, IT, customer support, sales and administrative roles.

FlexJobs, a job search engine specializing in remote-work opportunities, analyzed its user database to determine which career categories had the highest number of workers but the fewest opportunities, as well as the areas where there are more opportunities than workers to fill them.

Job seekers hoping to use their backgrounds in administration, data entry, nonprofits and media may face tough competition among many other applicants and a lower number of available openings. Meanwhile, those with skills in STEM, pharmaceuticals, foreign languages and social work may have an easier time using their background to secure a fully remote job.

Based on the career site's 34,000 jobs across 50 job categories, here are the most and least competitive remote jobs on the market.
