Some!studies!found!that!children’s!own!perceptions!of!their!neighbourhood!were!related! to! their! emotional! wellNbeing! and! behaviour! (Shumow! et! al.,! 1998;! Guerra! et! al.,! 2003;! Meltzer! et! al.,! 2007;! Eriksson! et! al.,! 2012).!

2.5 Summary,
Bronfenbrenner’s! ecological! model! of! human! development! postulates! that! early! experiences! are! shaped! by! interactions! with! the! immediate! as! well! as! the! wider! environment,!and!that!the!different!spheres!of!influence!are!interrelated,!leading!to!direct! and!indirect!effects.!The!review!of!the!literature!on!neighbourhoods!and!children’s!socioN emotional!and!cognitive!development!has!largely!supported!this!view.!While!the!family!as! the! most! direct! influence! is! undoubtedly! the! most! important! determinant! of! healthy! development,!this!review!found!a!large!body!of!research!showing!that!children’s!lives!are! influenced! also! by! where! they! live.! However,! there! was! also! some! conflicting! evidence! regarding! the! role! of! neighbourhood! deprivation! for! children’s! socioNemotional!
development,!as!well!as!regarding!the!potential!mechanisms!at!play.!!
Three! influential! reviews! have! outlined! the! possible! pathways! through! which! neighbourhood! effects! are! thought! to! work:! norms! and! collective! efficacy,! relationships! and!institutional!resources.!The!research!published!since!1998!lends!empirical!support!to! all! of! these,! albeit! to! differing! degrees.! The! role! of! social! processes! for! children’s! socioN emotional! development! has! been! generally! supported,! however! there! is! considerable! uncertainty! regarding! a! mediating! role! of! maternal! mental! health! and! parenting,! as! few! studies! attempted! to! disentangle! mediation! and! confounding.! For! cognitive! outcomes,! studies! have! mainly! looked! at! the! effects! of! neighbourhood! disadvantage! and! affluence,! largely! supporting! independent! relationships! especially! for! measures! of! affluence.! However,!the!associations!with!maternal!mental!health!and!parenting!are!even!less!clear! for!children’s!cognitive!skills.!!
The! availability! and! quality! of! institutional! resources! featured! rarely! in! the! reviewed! literature,!but!there!is!some!emerging!evidence!that!school!choice!might!play!an!important! role! for! children’s! cognitive! development.! Only! two! studies! have! considered! neighbourhoods! and! schools! simultaneously,! and! together! with! the! findings! from! experimental!studies,!the!results!point!towards!a!promising!route!for!further!research.!! The! main! limitations! of! the! reviewed! studies! are! data! constraints! regarding! available! covariates,! issues! with! sameNsource! bias! and! for! some,! the! definition! of! neighbourhood! boundaries.!Also,!few!studies!have!so!far!been!conducted!on!UK!data,!and!it!needs!to!be! tested!whether!the!findings!from!other!countries!hold!true!in!the!UK!context.!
To!summarise!the!main!gaps!in!current!knowledge,!one!unresolved!question!is!the!role!of! maternal! mental! health,! as! findings! have! so! far! been! inconsistent.! What! is! missing! are! studies! which! examine! the! whole! pathway! from! neighbourhood! exposure! via! maternal! mental!health!and!parenting!to!child!outcomes.!
Another! question! which! has! been! understudied! is! the! role! of! institutional! resources,! in! particular! the! contribution! of! schools! to! the! neighbourhood! effect.! The! two! important! studies! which! have! estimated! the! variability! in! cognitive! outcomes! between! neighbourhoods! and! schools! had! only! limited! access! to! potential! confounding! variables! (Leckie,!2009;!Rasbash!et!al.,!2010).!And,!neighbourhoods!and!schools!have!not!yet!been! examined!simultaneously!in!relation!to!children’s!emotional!wellNbeing!and!behaviour.! Further,! while! there! is! a! general! assumption! that! neighbourhoods! might! affect! boys! and! girls!differently,!there!is!currently!no!consensus!how!potential!effects!play!out!in!relation!to! gender.!
