Taylor Swift's 'Reputation' is by far the best-selling Album by a Female Artist in 2017 with year end sales of 2,981,000! 'Reputation' is Taylor's sixth studio album, released on November 10, 2017, through Big Machine Records. The record was produced by Jack Antonoff, Max Martin, Shellback and Taylor herself, who also serves as the executive producer. Ed Sheeran and American rapper Future featured on the Album.

Worldwide, 'Reputation' sold two million copies in its first week. A week prior to the album's release, pre-orders for it were reported to be over 400,000 units in the United States alone. According to Nielsen SoundScan, the album sold roughly 700,000 copies during its first day in the country and 1.05 million within four days of release, becoming 2017's biggest-selling album in the US! The album ultimately became Swift's fifth N°1 Album on the US Billboard 200 when it debuted atop the chart with 1.238 million album-equivalent units that consisted of 1.216 million traditional sales, becoming her fourth album to sell a million copies in the country in its first week. As a result, Swift became the only act to have four albums sell over a million copies there within a week since Nielsen Soundscan began tracking sales in 1991. 'Reputation' also had the largest album opening in the United States since Adele's '25' in 2015, as well as the 10th largest overall sales week in the US for an album since Nielsen SoundScan tracked its sales, and became the first album since '25' to sell a million copies there within a week.

With 256,000 more album-equivalent units earned and another 232,000 copies sold the week after, 'Reputation' stayed at N°1 and became the 1st Album to top the country's chart for two weeks since Jay-Z's 4:44, the first by a female to overall spend more than one week at the summit since Rihanna's Anti in 2016, and the first by a female to hold the highest position for its first two weeks since Adele's '25'. 'Reputation' then became the fourth album to spend three or more weeks at the top spot during 2017 after 'Starboy' by The Weeknd, 'More Life' by Drake, and 'Damn' by Kendrick Lamar as well as the first album since '25' by a female artist to do so overall, receiving 147,000 more album-equivalent units and selling an additional 131,000 copies during its third week. The album subsequently dropped to N°3 in its fourth week with 70,000 copies sold and 112,000 album-equivalent units earned before returning to the top spot three weeks later.

After selling 50,000 copies in Canada during its first day on sale, the LP also became Swift's fifth Album to top the Canadian Albums Chart, entering at N°1 with 80,000 copies among 81,000 consumption units.
