Question: What fraction of the population of the state where the most successful artist of that season of American Idol is from was enslaved in 1860?

<P0-S0> some in the entertainment industry were critical of the star-making aspect of the show. <P0-S1> usher, a mentor on the show, bemoaning the loss of the "true art form of music", thought that shows like american idol made it seem "so easy that everyone can do it, and that it can happen overnight", and that "television is a lie". <P0-S2> musician michael feinstein, while acknowledging that the show had uncovered promising performers, said that american idol "isn't really about music. <P0-S3> it's about all the bad aspects of the music business – the arrogance of commerce, this sense of 'i know what will make this person a star; artists themselves don't know.' <P0-S4> " that american idol is seen to be a fast track to success for its contestants has been a cause of resentment for some in the industry. <P0-S5> leann rimes, commenting on carrie underwood winning best female artist in country music awards over faith hill in 2006, said that "carrie has not paid her dues long enough to fully deserve that award". <P0-S6> it is a common theme that has been echoed by many others. <P0-S7> elton john, who had appeared as a mentor in the show but turned down an offer to be a judge on american idol, commenting on talent shows in general, said that "there have been some good acts but the only way to sustain a career is to pay your dues in small clubs". <SEP> <P1-S0> Since the show's inception in 2002, ten of the fourteen Idol winners, including its first five, have come from the Southern United States. <P1-S1> A large number of other notable finalists during the series' run have also hailed from the American South, including Clay Aiken, Kellie Pickler, and Chris Daughtry, who are all from North Carolina. <P1-S2> In 2012, an analysis of the 131 contestants who have appeared in the finals of all seasons of the show up to that point found that 48% have some connection to the Southern United States. <SEP> <P2-S0> while slaveholding was slightly less concentrated than in some southern states, according to the 1860 census, more than 330,000 people, or 33% of the population of 992,622, were enslaved african americans. <P2-S1> they lived and worked chiefly on plantations in the eastern tidewater. <P2-S2> in addition, 30,463 free people of color lived in the state. <P2-S3> they were also concentrated in the eastern coastal plain, especially at port cities such as wilmington and new bern, where a variety of jobs were available. <P2-S4> free african americans were allowed to vote until 1835, when the state revoked their suffrage in restrictions following the slave rebellion of 1831 led by nat turner. <P2-S5> southern slave codes criminalized willful killing of a slave in most cases. <SEP> <P3-S0> Other contestants, such as Hicks, McPhee, Bucky Covington, Mandisa, Kellie Pickler, and Elliott Yamin have had varying levels of success. <P3-S1> Despite being eliminated earlier in the season, Chris Daughtry (as lead of the band Daughtry) became the most successful recording artist from this season. <SEP> <P4-S0> This was a smaller proportion than in many Southern states. <P4-S1> The state did not vote to join the Confederacy until President Abraham Lincoln called on it to invade its sister state, South Carolina, becoming the last or second-to-last state to officially join the Confederacy. <P4-S2> In 1860, North Carolina was a slave state, in which one-third of the population was enslaved. <P4-S3> The title of "last to join the Confederacy" has been disputed; although Tennessee's informal secession on May 7, 1861, preceded North Carolina's official secession on May 20, the Tennessee legislature did not formally vote to secede until June 8, 1861.
