We find the largest correlations between siblings, especially identical twins. Grademate and neighbor correlations are small. Peer-based correlations are considerably larger than grademate and neighbor correlations but not larger than most sibling correlations. The data suggest that family-based factors are several times more powerful than neighborhood and school contexts in affecting adolescents\u2019 achievement and behavior.<\/jats:p>","DOI":"10.1353\/dem.2001.0026","type":"journal-article","created":{"date-parts":[[2007,2,7]],"date-time":"2007-02-07T02:28:00Z","timestamp":1170815280000},"page":"437-447","source":"Crossref","is-referenced-by-count":142,"title":["Sibling, peer, neighbor, and schoolmate correlations as indicators of the importance of context for adolescent development"],"prefix":"10.1215","volume":"38","author":[{"given":"Greg J.","family":"Duncan","sequence":"first","affiliation":[{"name":"Institute for Policy Research, Northwestern University, 2040 Sheridan Road, Evanston, IL 60208"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johanne","family":"Boisjoly","sequence":"additional","affiliation":[{"name":"Department of Human Sciences, University of Quebec at Rimouski, Rimouski, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathleen","family":"Mullan Harris","sequence":"additional","affiliation":[{"name":"Department of Sociology, University of North Carolina at Chapel Hill, Chapel Hill, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"73","reference":[{"key":"2021031615345364300_CR1"},{"key":"2021031615345364300_CR2","first-page":"21","article-title":"The Influence of Male and Female Best Friends on Adolescent Sexual Behavior","volume":"20","author":"Billy","year":"1985","journal-title":"Adolescence"},{"key":"2021031615345364300_CR3","doi-asserted-by":"crossref","first-page":"1055","DOI":"10.1126\/science.7195071","article-title":"Familial Studies of Intelligence: A Review","volume":"212","author":"Bouchard","year":"1981","journal-title":"Science"},{"key":"2021031615345364300_CR4","doi-asserted-by":"crossref","DOI":"10.4159\/9780674028845","volume-title":"The Ecology of Human Development: Experiments by Nature and Design","author":"Bronfenbrenner","year":"1979"},{"key":"2021031615345364300_CR5","volume-title":"Neighborhood Poverty: Context and Consequences for Children","author":"Brooks-Gunn","year":"1997"},{"issue":"1","key":"2021031615345364300_CR6","doi-asserted-by":"crossref","first-page":"65","DOI":"10.1086\/443913","article-title":"Toward a More Appropriate Conceptualization of Research on School Effects: A Three-Level Hierarchical Linear Model","volume":"97","author":"Bryk","year":"1988","journal-title":"American Journal of Education"},{"key":"2021031615345364300_CR7","volume-title":"HLM: Hierarchical Linear and Nonlinear Modeling With the HLM\/2Ll and HLM\/3L Programs","author":"Bryk","year":"1996"},{"key":"2021031615345364300_CR8","doi-asserted-by":"crossref","first-page":"228","DOI":"10.2307\/2093201","article-title":"Problems in Making Policy Inferences From the Coleman Report","volume":"35","author":"Cain","year":"1972","journal-title":"American Sociological Review"},{"key":"2021031615345364300_CR9","first-page":"97","article-title":"Labor Market Effects of School Quality: Theory and Evidence","volume-title":"Does Money Matter?
