From 2000 to 2010 and additional 4.2 million workers were employed at their own homes, a report titled "Home-Based Workers in the United States: 2010," said.
A comprehensive survey found that there were 9.5 million workers who labored for at least one day a week at home in 1999, a number that swelled to 13.4 million in 2010.
That was a jump from 7.8 percent of all workers to 9.5 percent, the report said.
Regarding income, the highest average involved workers who mixed it up, working at home and away from home.
So-called mixed workers earned an average of $96,300, while workers who only worked from home earned an average of $74,000.
In contrast, workers who never worked at home, so-called on site workers, earned an average of $65,600 per year, the report said.
