The viewership for Netflix series "House of Cards" declined and became predominantly female by its last season, new data finds.

Only 44 percent of the fifth season's viewers were women, but that number leapt to 54 percent in the sixth and final season, according to new data from Nielsen's SVOD Content Ratings, Fast Company reports.

The show was reworked for its final season after sexual misconduct allegations leveled against its former leading man, Kevin Spacey, led to him being removed. 

Robin Wright, who plays Spacey's character's wife in the show, took the spotlight in the final season. 

Fast Company reported that the audience also skewed older for the final season.

The amount of 18- to 34-year-olds who watched dropped from 35 percent in Season 5 to 22 percent in the final season, according to Nielsen. 

At the same time, the number of viewers over 65 doubled to 21 percent. 

As the show's demographics shifted, its general viewership declined. 

The first episode of Season 6 averaged 2.9 million U.S. viewers within the first week of its release.

Viewership dropped to 1.2 million by the fifth episode of the eight episode season.

The season finale had an audience of only 901,000 viewers.

Fast Company notes that the show still had a decent audience size compared to some of Netflix's cable rivals, but viewership is nonetheless a notable drop.
