Children are keen Internet shoppers with more than half having bought something online, research has shown.

Around 53 percent of children aged between 7 and 16 said they had bought something over the Internet, 10 percent more than in 2004, according to Halifax.

Boys were more likely to be Internet shoppers than girls, with 60 percent of boys saying they had bought items online, compared with just 46 percent of girls.

Unsurprisingly, older children were more likely to use the Internet to shop than younger ones, with nearly three quarters of 12-16-year olds shopping online, compared to just 29 percent of 7-to-11-year olds who said they had bought something.

More than half of children preferred buying things over the Internet to buying them on the high street, while 61 percent of those who had bought things online said it was easier to buy certain items over the Internet than in shops.

However, boys were more likely to always prefer buying things online, while girls were more likely to still like the actual high street shopping experience.

The most common items for young people to buy over the Internet were CDs, tapes and computer games and equipment. Some children had bought DVDs and videos, while some had bought gifts.

Children spent most money on computer games and equipment, with 13 percent saying they spent more than $20 online on these items a year, followed by 12 percent who spent more than $20 a year on mobile phones and 11 percent who spent the same amounts on clothes.

Cheryl Millington, head of savings at Halifax, said, “ We are not only seeing the emergence of a generation of young consumers, but also keen cyber-consumers. While children often lead the way in Internet use within the family home, parents have an important role to play in ensuring they stay safe while online.”
