Network for Obesity:Linked administrative data

How can two ESRC resources help: Administrative Data Research Network UK Census Longitudinal Studies

Introduce the services Examples of data available How to access the data

ADRN and UK LS ADRN – linking administrative and

potentially census data – 100% of populationsVery large studies ie ~millions of individualsData limited to that asked

UK LS – 40 years of follow-up of samples ~ 300,000 - 500,000Census, vital registration, educationHouseholds

Three Census-Linked Longitudinal Studies

CeLSIUS (supporting ONS Longitudinal Study)

SLS-DSU (supporting Scottish Longitudinal Study)

NILS-RSU (supporting Northern Ireland Longitudinal Study)

Key Features of Longitudinal Change

Comparison of same group over time (Age effects) Comparisons over time (Period comparisons) Comparisons between cohorts over time (Cohort

effects)(Source: Findlay et al, 2015) New mobilities across the lifecourse, Population Space and Place, 21)

What does the ADRC-S do?

What does the ADRC-S do?Develop the capacity to:

Engage with the public & effectively communicate value/ worth of endeavour and the safety of the infrastructure

Respond to the legal environment emerging out of cross-sectoral linkage

Store, access and link large complex datasets exploiting new linkage methods

Geocode administrative data from the 1850s to present & provide means of adding contextual information to individual records

Extract information from free text resourcesProduce synthetic versions of linked

administrative datasets

Synthetic data - synthpop

A tool for producing synthetic versions of microdata containing confidential information so that they are safe to be released to users for exploratory analysis and preparing code
