In agreement with the Declaration of the Human Rights, drafted at the very beginning of the French Revolution, slavery was abolished in the French colonies overseas. For some strange reason Napoleon Bonaparte revoked that decree in 1802 during the Consulate, which resulted in the slave revolt of Haiti and ensuing independence in 1803.
Integration”2 is the term the panel uses to describe the changes that both immigrants and their descendants—and the society they have joined—undergo in response to migration. The panel defines integration as the process by which members of immigrant groups and host societies come to resemble one another (Brown and Bean, 2006). That process, which has both economic and sociocultural dimensions, begins with the immigrant generation and continues through the second generation and beyond (Brown and Bean, 2006). The process of integration depends upon the participation of immigrants and their descendants in major social institutions such as schools and the labor market, as well as their social acceptance by other Americans (Alba et al., 2012). Greater integration implies parity of critical life chances with the native-born American majority. This would include reductions in differences between immigrants or their descendants vis-a-vis the general population of native-born over time in indicators such as socioeconomic inequality, residential segregation, and political participation and representation. Used in this way, the term “integration” has gained near-universal acceptance in the international literature on the position of immigrants and their descendants within the society receiving them, during the contemporary era of mass international migration.
