Instagram has said it has grown its monthly active user base to 500 million.

300 million of those users of the photo sharing site use it every day, the Facebook-owned company says.

The latest figure amounts to a more than doubling of the five-year-old company's user base in the past two years.

More than 80% of Instagram users are outside the US, the firm says.

According to data contained in the Ipsos MRBI Social Networking Quarterly published in April, a quarter of all adults in Ireland have an Instagram account.

Use in Ireland has been growing in recent years, with more than half of those users saying they use it every day.

Globally more than 95 million photos and videos are shared every 24 hours on the site.
