Do you feel as though you're constantly on the Internet? If so, you're not alone as one in five Americans admit they're online "almost constantly."

According to the latest report from Pew Research Center, 21 percent of US adults agreed with the above phrase. Because this is the first time Pew has included that response in their survey, there is no previous data to make an apples-to-apples comparison against.

Elsewhere, 42 percent of respondents said they go online several times a day followed by just 10 percent that do so "about" once a day.

Combined, 73 percent of adults say they use the Internet daily while 13 percent do so less frequently (perhaps just a few times a week). The remaining percentage of respondents said they don't use the Internet at all.

Unsurprisingly, there's a direct correlation between Internet usage and age. Pew found that 36 percent of people between the age of 18 and 29 go online almost constantly. That figure drops to 28 percent among those aged 30 to 49 while only 12 percent of those between 50 and 64 use the Internet that often. Among senior citizens aged 65 and older, only six percent said they go online almost constantly.

Data further reveals that income and level of education directly impacts Internet usage. Those with a high school education or less and those that earn less than $30,000 annually get online far less than those with a college degree and people that make $75,000 or more each year.
