Migration and commuting • Migration and commuting are important agents of change • Migration behaviour varies with • The number of persons who move together • The presence (or not) of existing residents in the destination household • Relationships between migrants and existing residents
Migration and commuting • Migration affects patterns of commuting • Change in location of employment • Change in journey to work • Trade-offs between migration and commuting • Long distance weekly commuting • Dual career households
Aims • Investigate trends and processes related to characteristics of individuals and groups of migrants • Investigate interactions between migration and commuting behaviour • Investigate how relationships between and within groups of migrants and residents explain mobility patterns
Data sources • 2001 Census • Longitudinal Study • Labour Force Survey • British Household Panel Survey
Objectives • Classifying moving group types
Moving groups • A new innovation in the 2001 Census • Allows separate groups within the household to be identified • Previous Censuses had only ‘migrants’ and ‘wholly moving households’
Moving groups in the UK • About 3.5million groups identified • These contained 5.8million migrants • Group size distribution is different for wholly moving and other groups Source: 2001 Census: Special Migration Statistics Level 1; Table MG106
Objectives • Classifying moving group types • Describe spatial patterns of internal migration in UK by various groups
Spatial patterns of migration • How do preferred destinations vary for groups of different sizes? • Is there a difference in the distances travelled?
Objectives • Classifying moving group types • Describe spatial patterns of internal migration in UK by various groups • Describe spatial patterns of commuting behaviour by household composition
Spatial commuting patterns • Using the Census, explore patterns at an aggregate scale • By family status • By living arrangements • Using the Labour Force Survey, explore patterns for individuals at national scale
Objectives • Classifying moving group types • Describe spatial patterns of internal migration in UK by various groups • Describe spatial patterns of commuting behaviour by household composition • Relate spatial behaviour to relationships within household
Relationship matrix • Allows a partial grid to be constructed • Remainder is derived • Information for 6th and subsequent persons is limited Source: 2001 Census form H1. ONS
Relationship matrix • Allows wider range of family types to be identified • Extended families • Multi-generational families • Allows easier identification of hidden families
Relating spatial behaviour and household relationships • Use records from Longitudinal Study • Explore patterns for a sample of individual households • How well do aggregate patterns reflect range of individual patterns? • Analysis likely to be at national level • Explore long-term stability of moving groups
Objectives • Classifying moving group types • Describe spatial patterns of internal migration in UK by various groups • Describe spatial patterns of commuting behaviour by household composition • Relate spatial behaviour to relationships within household • Link migration patterns to commuting behaviour
Linking migration and commuting patterns • Use BHPS to study motivations for migration and impact on households • Changes in material circumstance • Changes in household composition • Use LFS to study • Changes in commuting behaviour • Find comparator households to those in LS
