Project Description

Summary:

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.
