Cristiano Ronaldo has one of the most popular Instagram accounts as of April 2024.

              The Portuguese footballer is the most-followed person on the photo sharing app platform with 628 million followers. Instagram's own account was ranked first with roughly 672 million followers.

              How popular is Instagram?

              Instagram is a photo-sharing social networking service that enables users to take pictures and edit them with filters. The platform allows users to post and share their images online and directly with their friends and followers on the social network. The cross-platform app reached one billion monthly active users in mid-2018. In 2020, there were over 114 million Instagram users in the United States and experts project this figure to surpass 127 million users in 2023.

              Who uses Instagram?

              Instagram audiences are predominantly young – recent data states that almost 60 percent of U.S. Instagram users are aged 34 years or younger. Fall 2020 data reveals that Instagram is also one of the most popular social media for teens and one of the social networks with the biggest reach among teens in the United States.

              Celebrity influencers on Instagram
              Many celebrities and athletes are brand spokespeople and generate additional income with social media advertising and sponsored content. Unsurprisingly, Ronaldo ranked first again, as the average media value of one of his Instagram posts was 985,441 U.S. dollars.

This dataset displays public elementary and secondary schools throughout the country that are either single-sex schools or offer single-sex classes for the 2008-2009 school year. For the 2008-2009 school year, there are at least 392 public schools in the United States offering single-sex educational opportunities. Most of those schools are COED schools which offer single-sex CLASSROOMS, but which retain at least some coed activities. In some cases, the only coed activities are lunch and one or two electives, so the distinction between a single-sex school, and a coed school with single-sex classrooms, can become a semantic quibble. From March 2002 through July 2007, we tried to make a distinction between single-sex schools, on the one hand, and coed schools with single-sex classes, on the other hand. We listed single-sex schools on one web page, while coed schools with single-sex classes were listed on a separate web page. As it became increasingly obvious that the distinction was often arbitrary, we decided in August 2007 to begin listing all public schools offering single-sex classrooms on the same web page, which is this page. By our count, 97 of the 392 schools below qualify as single-sex schools, meaning that students attending any of those 97 schools have all their school activities -- including lunch and all electives -- in a setting which is all-boys or all-girls. Most of those 97 schools are single-sex campuses, such as the The Ann Richards School for Young Women which opened in Austin, Texas in August 2007. Note: Schools which offer single-sex classes only in physical education and/or health and/or sex education are NOT listed here. In addition, correctional schools for adjudicated delinquent juveniles are not listed here.
