Question: In 1860, what percent of the population of the state where the most successful artist from this season comes from were slaves?

<P0-S0> They lived and worked chiefly on plantations in the eastern Tidewater. <P0-S1> In addition, 30,463 free people of color lived in the state. <P0-S2> 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. <P0-S3> 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. <P0-S4> 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. <P0-S5> Southern slave codes criminalized willful killing of a slave in most cases. <SEP> <P1-S0> Other contestants, such as Hicks, McPhee, Bucky Covington, Mandisa, Kellie Pickler, and Elliott Yamin have had varying levels of success. <P1-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> <P2-S0> the invention of the cotton gin caused massive growth in the production of cotton in the united states, concentrated mostly in the south. <P2-S1> cotton production expanded from 750,000 bales in 1830 to 2.85 million bales in 1850. as a result, the region became even more dependent on plantations and slavery, with plantation agriculture becoming the largest sector of its economy. <P2-S2> while it took a single slave about ten hours to separate a single pound of fiber from the seeds, a team of two or three slaves using a cotton gin could produce around fifty pounds of cotton in just one day. <P2-S3> the number of slaves rose in concert with the increase in cotton production, increasing from around 700,000 in 1790 to around 3.2 million in 1850. by 1860, black slave labor from the american south was providing two - thirds of the world's supply of cotton, and up to 80% of the crucial british market. <P2-S4> the cotton gin thus ``transformed cotton as a crop and the american south into the globe's first agricultural powerhouse ''. <SEP> <P3-S0> two years later, the royal african company was inaugurated, receiving from king charles a monopoly of the trade to supply slaves to the british colonies of the caribbean. <P3-S1> from the outset, slavery was the basis of the british empire in the west indies. <P3-S2> until the abolition of the slave trade in 1807, britain was responsible for the transportation of 3.5 million african slaves to the americas, a third of all slaves transported across the atlantic. <P3-S3> to facilitate this trade, forts were established on the coast of west africa, such as james island, accra and bunce island. <P3-S4> in the british caribbean, the percentage of the population of african descent rose from 25 percent in 1650 to around 80 percent in 1780, and in the 13 colonies from 10 percent to 40 percent over the same period (the majority in the southern colonies). <P3-S5> for the slave traders, the trade was extremely profitable, and became a major economic mainstay for such western british cities as bristol and liverpool, which formed the third corner of the so-called triangular trade with africa and the americas. <P3-S6> for the transported, harsh and unhygienic conditions on the slaving ships and poor diets meant that the average mortality rate during the middle passage was one in seven. <SEP> <P4-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. <P4-S1> 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. <P4-S2> 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.
