Question: At what age did the rapper who released Carnival Vol. II: Memoirs of an Immigrant emigrate to the United States?
Context: Carnival Vol.  II: Memoirs of an Immigrant is the sixth studio album by former Fugees member and rapper Wyclef Jean, released in 2007 as the sequel to his first solo album, "The Carnival".  Speaking to noted urban writer Pete Lewis of the award-winning 'Blues & Soul' in September 2007, Wyclef explained his thinking behind the album: "Titling it 'The Carnival 2' was down to 'The Carnival' back in '97 being my first multi-cultural CD.  It had rhythms from all over the world, and in that way this new record is the sequel.  You know, there's a revolution of culture going on around the world today where the United Nations is everywhere!  You go into a room, and everybody's from a different country.  It's like we're ALL immigrants!  Some of these people may be listening to bhangra, some to hip hop, some to rock... And, when you put that fusion together, it unites people through music." Věra Waldes - Hromádková (3 June 1914 - 24 November 1995) was a prominent fighter in communist anti-nazi resistance in Paris during World War II.  She was born in Dresden to Zikmund Waldes, who was a wealthy Czech entrepreneur and brother of Jindřich Waldes.  She refused to emigrate to the United States with her family and instead joined anti-nazi resistance in France.  In Paris she met and married one of the leaders of Czech resistance in Paris region, Otakar Hromádko.  Between 1945 and 1968 she lived in Czechoslovakia and after the Warsaw Pact invasion of Czechoslovakia in 1968 she emigrated to Switzerland.  After the Velvet Revolution in 1989, she attempted to regain a part of her family property in the Czech Republic. An American Tail is a 1986 American animated musical adventure family comedy-drama film directed by Don Bluth and produced by Sullivan Bluth Studios and Amblin Entertainment.  It tells the story of Fievel Mousekewitz and his family as they emigrate from Russian Empire-controlled territory of Ukraine to the United States for freedom.  However, he gets lost and must find a way to reunite with them.  It was released on November 21, 1986, to reviews that ranged from positive to mixed and was a box office hit, making it the highest-grossing non-Disney animated film at the time.  The success of it, "The Land Before Time", and Disney's "Who Framed Roger Rabbit", as well as Bluth's departure from their partnership, prompted Steven Spielberg to establish his own animation studio, Amblimation. Silent So Long is the second studio album by the European band Emigrate.  This album was released November 14, 2014 in Europe and was released in the United States on December 9, 2014. Overall, immigrants make up about 13% of the US population in any given year (currently about 42 million out of a total population of 318.9 million citizens.  Immigration begins to increase in the late teens and continues through early adulthood, which means that there are proportionally many fewer immigrant children currently in the school system.  However, immigrant and native-born populations become more equal as age increases, especially regarding education and income.  The Supreme Court of the United States ruled in 1982 in Plyler v. Doe that states cannot deny students an education on account of their immigration status, allowing students to gain access to the United States' public schooling system.  Further, Lau v. Nichols prohibited discrimination based on race or national origin. Johann Heinrich Lienhard (January 19, 1822, Bilten, Canton Glarus – December 19, 1903, Nauvoo, Illinois) was a Swiss immigrant to the United States.  He left Switzerland at the age of 21.  His memoirs for the years 1822 to 1850 are an important historical source regarding California Trail and Sutter's Fort in California from 1846 to 1850. Rufus C. Somerby (1832–1903) was an entertainer, showman, and panoramist in the mid-nineteenth century, and one of a very few men of his profession to leave behind any memoirs or account of his activities.  He is chiefly known through a series of articles published in 1903 and 1904 in "The Billboard", the ancestor of today's "Billboard Magazine," which at the time was a trade journal for circus, carnival, and theatrical performers and managers.  Somerby operated several moving panoramas under the management of Boston's George K. Goodwin, including a panorama of "Dr. Kane's Arctic Voyages," and also was involved in mechanical theatres.  He worked as an agent for P.T. Barnum, bringing one such mechanical theatre, "Thiodon's Theatre of Arts," from the United Kingdom to the United States for an exhibition at Barnum's American Museum.  Later, after this mechanical show was completed his run, he oversaw its re-making into two smaller such theatres, one of which had its figures re-painted to as to present not "The Battle of Balaclava" in the Crimean War, but the assault on Fort Sumter, by a panorama broker in Providence, Rhode Island. Emigrate is the first full-length self-titled studio album by the European band Emigrate.  This album was released August 31, 2007 in Europe and was released in the United States and in Australia on January 29, 2008 but still has no Worldwide release dates. The Children of Immigrants Longitudinal Study (CILS) was designed to study the adaptation process of the immigrant second generation.  Immigrant second generation is defined broadly as United States-born children with at least one foreign-born parent, or children born abroad but brought at an early age to the United States.  The original survey was conducted with large samples of second-generation immigrant children attending the 8th and 9th grades in public and private schools in the metropolitan areas of Miami/Ft.  Lauderdale in Florida and San Diego, California.  Conducted in 1992, the first survey had the purpose of ascertaining baseline information on immigrant families, children's demographic characteristics, language use, self-identities, and academic attainment.  The total sample size was 5,262.  Respondents came from 77 different nationalities, although the sample reflects the most sizable immigrant nationalities in each area.  Three years later, corresponding to the time in which respondents were about to graduate from high school, the first follow-up survey was conducted.  Its purpose was to examine the evolution of key adaptation outcomes including language knowledge and preference, ethnic identity, self-esteem, and academic attainment over the adolescent years.  The survey also sought to establish the proportion of second-generation youths who dropped out of school before graduation.  This follow-up survey retrieved 4,288 respondents or 81.5 percent of the original sample.  Together with this follow-up survey, a parental survey was conducted.  The purpose of this interview was to establish directly characteristics of immigrant parents and families and their outlooks for the future including aspirations and plans for the children.  In total, 2,442 parents or 46 percent of the original student sample were interviewed.  During 2001-2003, or a decade after the original survey, a final follow-up was conducted.  The sample now averaged 24 years of age and, hence, patterns of adaptation in early adulthood could be readily assessed.  The original and follow-up surveys were conducted mostly in schools attended by respondents, greatly facilitating access to them.  Most respondents had already left school by the time of the second follow-up so they had to be contacted individually in their place of work or residence.  Respondents were located not only in the San Diego and Miami areas, but also in more than 30 different states, with some surveys returned from military bases overseas.  Mailed questionnaires were the principal source of completed data in this third survey.  In total, CILS-III retrieved complete or partial information on 3,613 respondents representing 68.9 percent of the original sample and 84.3 percent of the first follow-up.  Relevant adaptation outcomes measured in this survey include educational attainment, employment and occupational status, income, civil status and ethnicity of spouses/partners, political attitudes and participation, ethnic and racial identities, delinquency and incarceration, attitudes and levels of identification with American society, and plans for the future.
