As of 2012, estimates suggest that over fifty million U.S. workers (about 40% of the working population) could work from home at least part of the time, but in 2008 only 2.5 million employees, excluding the self-employed, considered their home to be their primary place of business. The number of employees reported to have worked from their home "on their primary job" in 2010 has been reported as 9.4 million (6.6% of the workforce), though, this number might include the self-employed. As of 2017, roughly 3.7 million employees—2.8% of the workforce—work from home at least half the time, Global Analytics Workplace reports. Very few companies employ large numbers of home-based full-time staff. The call center industry is one notable exception: several U.S. call centers employ thousands of home-based workers. For many employees, the option to work from home is available as an employee benefit but most participants only do so a fraction of the time. Top paid among work-from-home sectors are home-based physicians and radiologists in which it is suspected that they earn near the $1,975 median weekly income of physicians, as reported by the U.S. Bureau of Labor Statistics, making it a six-figure job. Studies show that at-home workers are willing to earn up to 30% less and experience heightened productivity. 
Freelance writers can more easily be thought of as a “writer for hire” or someone who is contracted out to write about a particular topic. If you have some writing chops, but don’t want to deal with all the extra work that goes into running a blog, you can hire yourself out and write for newspapers, large online publications and even other bloggers.
