Combined Longitudinal Study of the Second Generation in Spain data set, Waves 1, 2, and 3. This is the publicly available version of the ILSEG data (ILSEG is the Spanish acronym for Investigación Longitudinal de la Segunda Generación, Longitudinal Study of the Second Generation). Questions address the situations and plans for the future of young Spaniards who are children of immigrants to Spain, who were living in Madrid and Barcelona and attending secondary school in 2007-2008 and the 2011-2012 and 2015-2016 follow ups). The longitudinal study of the second Generation (ILSEG in its Spanish initials) represents the first attempt to conduct a large-scale study of the adaptation of children of immigrants to Spanish society over time. To that end, a large and statistically representative sample of children born to foreign parents in Spain or those brought at an early age to the country was identified and interviewed in metropolitan Madrid and Barcelona for wave 1. In total, almost 7,000 children of immigrants attending basic secondary school in close to 200 educational centers in both cities took part in the study. Because of sample attrition, wave 2 introduced a replacement sample. Additionally, a native born sample of children of Spaniards was also included to enable comparisons between native and immigrant-origin populations of the same age cohort.Topics include basic demographics, national origins, Spanish language acquisition, foreign language knowledge and retention, parents' education and employment, respondents' education and aspirations, religion, household arrangements, life experiences, and attitudes about Spanish society. Demographic variables include age, sex, birth country, language proficiency (Spanish and Catalan), language spoken in the home, number of siblings, mother's and father's birth country, religion, national identity, parent's sex, parent's marital status, parent's birth year, and the year the parent arrived in Spain.

This data archive provides the first large-scale longitudinal study of children of immigrants (one or both parents born abroad or brought to the host country at or before age five) and immigrant children (the 1.5 generation: older than age five but still in their childhood or adolescence) successfully carried out in Spain, or any Western European country. It was designed to replicate the "/data-archive?fid=CILS123P" Target="_blank">Children of Immigrants Longitudinal Study carried out in the United States in the 1990s and early 2000s. For Wave 1, almost 7,000 children of immigrants attending basic secondary school in close to 200 educational centers in both cities took part in the study.

The original survey was conducted in 2007-2008; four years later, the same sample was traced and re-interviewed either at school, via telephone, or through contact in the social media (Facebook and Twitter). Through these means, the research team was able to identify and re-interview 73 percent of the original sample for which retrieval information was available. An additional replacement sample of over 1,500 second generation youths of the same average age as the original respondents was interviewed in the same schools in which the original study took place. Finally, and for comparative purposes, a sample of approximately 1,600 native-parentage Spanish youths was interviewed at the same time.

Together the surveys cover all relevant aspects of adaptation and psycho-social development in late childhood and adolescence, including educational achievement and aspirations; labor market participation, occupation, and income; family structure and inter-generational relations; language knowledge, preferences, and use; friends' national origins and educational plans; national self-identification, self-esteem, and other psychological outcomes, and religion. To supplement the information from immigrant children, the study also conducted a person-to-person survey of 25 percent of their parents in 2010. They were interviewed in Spanish or in their native language. The parental survey is representative of the earlier studies sample, including near identical proportions of all foreign nationalities present in the latter.
