Nearly one in four Americans made money over the last 12 monthsby using their personal computersor other devices connected to the Internet.The Pew Research Center, an independent research group in Washington,found that people are using the Internet to find extra work.They go online to sell things such as used books and furnitureor they offer to provide servicessuch as babysitting, house cleaning or computer repairs.The Pew Center asked people if they make money from the Internetor computing devices, and, if so, what they do to earn their pay.The answers provided the findings of Pew's new reporton what has been called the "Gig Economy."Pew found that income earned on the Internet can come in many forms.Many Americans said they used their computers to do extra work.About five percent of Americans said they did online computer work over the last year.Some of these people said they had jobs that paid a few pennies each to take surveys.In these surveys, people are asked for their opinions ofdifferent products or well-known people.Others typed reports or other information on their home computers.Using digital devices to offer a service online was another way to earn income.About two percent of Americans earned money from ride-sharing companiessuch as Uber and Lyft.When drivers are ready to pick up passengers,they use their ride-share company's app.The computer program lets them knowwhen passengers are ready to be picked up and how to reach them.Some people make their homes, apartments, or rooms inside their homes,available for money to people visiting their cities.A popular website people use to makes rooms available is www.airbnb.com.Other people use apps on their computer devicesthat permit people to hire them to babysit,walk dogs or do repair or clean-up work.Apps operated from phones or tabletsconnect them to people looking for such services.About 60 percent of people involved in the gig economysay the income they earn is important to them.But just one in five people who sell things onlinesay the income is enough to be important to their lives.Only 16 percent believe doing online work will lead to a meaningful career.But 37 percent say the extra income earned from online jobshelps them make up for shortages in money.The number one reason people gave for taking online jobswas that the work gave them something to do and was fun.Pew said that reason was listed by 42 percent of people it questioned.But, opinions about the online economy are mixed.Sixty-eight percent say the gig economy is good for peoplewho want flexibility when they work.Flexibility means they do not have to work when they are at their regular jobsor have family or school events or other things they want or need to do.But, 23 percent say online work lets companies take advantage of employeesand only 16 percent believe they can build careers with gig work.By taking advantage, some people mean they do not get paid enoughfor work done through online companies.About one in five say they take online jobs to gain work experience,while 17 percent say it is because they cannot find other jobs.What kind of people work online or use online devices to find work?The answer appears to be: mostly people who already have jobs.According to Pew, 68 percent say they are already employed full time or part time.Twenty-three percent say they are students.Thirty-two percent say they have no other jobs.
