Commercial performance On its first day of sales, 4 shipped more than 10,000 copies in Poland,[126] more than 120,000 copies in Brazil,[129] and sold around 32,000 in the United Kingdom on its first day itself.[189] According to The Official Charts Company data, 4's opening day sales were more than the combined sales of its three nearest challengers, being Adele's 21 (2011), Lady Gaga's Born This Way (2011), and Adele's first studio album 19 (2008) for that day.[189] After a complete week of sales, 4 debuted atop the UK Albums Chart on July 4, 2011, with first-week sales of 89,211,[190] In its second week of release, 4 remained atop the chart, selling 44,929 copies.[191] In 2011 it was the 18th best selling album in the UK, selling 451,000 copies.[192] It was also the fourth biggest selling R&B / hip hop album of 2011 in the UK.[193] For the week commencing July 4, 2011, 4 opened at number two on the Australian ARIA Albums chart, giving Knowles her highest ever chart debut on that chart,[194] and started at number one on its urban chart.[195] 4 debuted at number three on the Canadian Albums Chart selling 8,700 copies in its first week,[196] and at number two in France selling 12,393 copies in its first week.[197] According to the Japanese music charting site Oricon, the album debuted at number ten, selling 18,984 copies for the week ending July 11, 2011.[198] In the United States, 4 debuted at number one on the Billboard 200, with first-week sales of 310,000 copies.[199] This gave Knowles her fourth consecutive solo debut at the top of the chart and makes her the second female artist and third artist overall, to have her first four studio albums debut atop the Billboard 200.[199] 4's first-week sales became Knowles' lowest sales start with a studio album to date.[199] However, Keith Caulfield of Billboard magazine commented that the album was not released during the festive season and that Knowles was so far lacking a hit single, which could help explain the album's softer entry.[199] Its lead single, "Run the World (Girls)" peaked at No. 29 on the Billboard Hot 100 – the first time the first single from a Knowles' studio set has missed the top ten. He finally added that "4's bow is pretty big for 2011. It marks the third-largest sales week of the year, after the [number one] bows of Lady Gaga's Born This Way and Adele's 21."[199] 4 became the ninth solely-numerical titles (including roman numerals) to have reigned since the chart launched as a weekly survey the week of March 24, 1956.[200] In its second week, the album remained at number one on the Billboard 200, despite an 63% sales decrease, selling 115,000 copies. It hence became the first album by Knowles to top the Billboard 200 albums chart for more than one week.[201] On August 1, 2011, the album was certified platinum by the Recording Industry Association of America (RIAA), for shipments of one million copies to retail stores.[202] For the week ending September 10, 2011, 4 fell to number 12 on the US Billboard 200,[203] after having spent eight consecutive week in the top 10 positions.[204] However, after Knowles' performance at the 2011 MTV Video Music Awards, 4 registered an 87% rise in sales, allowing it to re-enter the top 10 of the US Billboard 200 at number seven, selling 39,000 copies for the week ending September 17, 2011.[205] As of February 2012, 4 has sold 1,135,700 copies in the United States.[206]
