Nearly half of the people with Twitter accounts do not tweet, according to a recent report the Financial Express reported.

Twopcharts, a firm that monitors Twitter usage, revealed that 44 percent of 974 million Twitter users have never sent a tweet in the last quarter of 2013. This number may be alarming to Twitter as it is trying to show advertisers that it is a medium through which they can reach out to consumers.

Twopcharts is unable to track when someone has logged into their account. It can only tell when the account retweets or tweets it's a message.

The report also highlighted Twitter's user retention rate. According to Twopcharts, around 542.1 million accounts have sent at least one tweet since they were created, which suggests that more than half of the accounts in existence have actively tried out the service. However, only 23 percent of those accounts have tweeted sometime in the last 30 days, Techie News reported.

A previous report from the firm said only 40 percent of the 20 million new accounts on Twitter each month send at least one tweet during the first month that they signed up.

According to The Wall Street Journal, Twitter said it has 241 million monthly active users the last three months of 2013. The social media site defines a monthly active user as an account that logs in at least once a month. A person does not have to tweet to be considered a monthly active user.

User tweets, retweets, favorites and other actions help Twitter generate advertising revenue. The microblogging site has been widening its appeal this week with a "photo-heavy redesign for profile pages that was similar to Facebook's timeline."

A Twitter spokesman told declined to comment on the report, saying the company does not comment on third-party data.
