Who will fill in the internet census?

A blog on the UCL CeLSIUS website by Oliver Duke-Williams

“This weekend (Sunday March 21, 2021) we will all be asked to fill in our census forms. There’s a key difference this time: the Office for National Statistics, which runs the operation, is aiming for at least 75 per cent of our returns to be submitted online, and the early signs are that millions of people have already responded.” Published on March 19th, 2021

The ONS Longitudinal Study: how does it work?

A blog on the UCL CeLSIUS website by Nicola Shelton

“Back in the late 1960s there was concern that policymakers had too little information about births and deaths: death certificates recorded only limited information and even the occupation of the deceased could be recorded inconsistently. Similarly it was impossible to use information from birth registrations to look at patterns of fertility – how were children spaced within families, for instance? And so the ONS Longitudinal Study was born.” Published on March 18th, 2021

The 2021 Census: What will it tell us about life after Covid-19?

A blog on the UCL CeLSIUS website by Nicola Shelton

“When the 2021 census was first planned, we thought some of the biggest research questions to emerge from it would be around the effects of Brexit. But while those are still live, researchers and others will be watching with interest to see what this snapshot of Britain in 2021 will tell us about the effects of Covid-19.” Published on March 9th, 2021.

Windrush migrants in the ONS Longitudinal Study

CeLSIUS have produced a research brief outlining how the ONS LS can be used to identify Windrush migrants in England and Wales. This revealed statistics such as:

  • In 2011 there were around 1,735 Windrush migrants who had entered the country as children prior to 1971 and who did not hold any passport
  • Overall 3,744 Windrush migrants were identified who did not hold any passport

The brief also highlights how the ONS LS could be used for more in-depth research on the Windrush migrant population.

CALLS Hub conference, Friday March 23rd 2018

On Friday 23rd March, we hosted a very successful conference in St Andrews. The goals of the conference were to celebrate what CALLS Hub has achieved in the last 5.5 years by bringing together the 3 UK Census-based Longitudinal Studies, and also to showcase the next generation of young researchers who are using the Studies. We finished the day with an inspiring and challenging discussion panel session from four speakers drawn from experts in the fields of Local Authority research, academic research, charitable organisations and generating impact.

Below you will find a downloadable version of the conference booklet as well as links through to the abstracts of the talks. Many of these already include downloadable copies of the presentation slides.

Updated Citation Analysis – ‘Exploring the reach of the Census-based Longitudinal Studies 2010-2017’

(download as a PDF 709kB)

Overview

The Northern Ireland Longitudinal Study, ONS Longitudinal Study (England and Wales), and Scottish Longitudinal Study include a vast range of data relevant to many different types of research question. Their combination of administrative, census and health data across time make them a rich and unique set of resources. Examples of the types of research enabled by these features of the LSs include: Assessing the contributions of the workplace and employment history, the local area, and individual health and social factors from childhood and adulthood to extended working lifeThe role of subject choices in secondary education on further education studies and labour market outcomes and Population characteristics of stigma, condition disclosure and chronic health conditions.

As an exploration of the many ways in which the LSs have been used, CALLS have conducted an analysis of the journal papers produced by LS researchers. This citation analysis demonstrates the impressive range of academic fields to which LS-based research has contributed in the last 7 years. Research featured in over 70 journals, and spanned more than 50 Scopus subject categories.

Research based on the LSs is regularly published in top quality international peer reviewed journals such as Demography, the International Journal of Epidemiology and Population, Space and Place. Eighteen papers included in the citation analysis were published in journals ranked within the top 5 for one of the following SCImago subject areas:

  • Geography, Planning and Development
  • Epidemiology
  • Demography
  • Health (Social Science)
  • Urban Studies
  • Community and Home Care
  • Applied Psychology
  • Pulmonary and Respiratory Medicine
  • Biotechnology

Papers had excellent citation rates indicating the unique contribution LS data offer. Forty papers had been cited 10 or more times, and 13 papers had more than 20 citations.

NILS41217 (avg 5.6)
ONS LS70454 (avg 7.2)
SLS43421 (avg 11.1)
All LSs1391018 (avg 8.0)

 

The subject categories of papers using the LSs reflect the strengths of the data that they offer. Whilst the categories were very similar,  ONS LS’s top 5 included ‘Demography’, whereas the SLS and NILS had a higher proportion of ‘Health (social science)’ papers, likely due to their excellent linkages with health data.

Overall the analysis shows the valuable contribution of the NILS, ONS LS and SLS to a diverse range of academic fields including medicine, demography, geography, economics, business, psychology, environmental science and more.

Although we only focus on publications in academic journals in this report, LS research has considerable impact in other formats such as briefing notes, books and presentations to government, and has also formed the basis of a variety of PhD Theses. A full list of outputs can be explored in our outputs database.

The raw data for the analysis can be downloaded at the bottom of this page.

Methods

Using the CALLS Hub outputs database a total of 139 published papers from the period January 2010 – October 2017 were identified from the three LSs. It should be noted that whilst CALLS and the RSUs actively solicit LS users to notify them of all outputs, and also conduct occasional literature searches to maximise capture, it is possible that some further papers exist.

All papers published in journals or regularly produced official publications – such as ONS Population Trends – were included. We did not include working papers in this analysis. Citation counts were gathered from Scopus, taking the final counts as of 21 November 2017. Impact Factors were taken from the Scopus project SCImago using the SJR2 indicator.

Results

The LSs combined

Of the 139 papers identified, 16 were from non-peer-reviewed journals such as Population Trends. Ten papers used more than one LS for their analysis. (see figure 1)

figure 1. Number of published papers per LS, Jan 2010 – October 2017. n = 139

Papers from the three LSs were published in a total of 73 different journals, spanning 52 SCImago Subject Categories in 13 Subject Areas (figure 2). SJR Impact Factors for the journals ranged from 0.104 to 10.113, with an average of 1.573.

SLS migration research to be enhanced with continuous GP registration data

Dawn Everington, SLS-DSU

SLS-DSU have been working on an exciting new data development which will soon be available to researchers. We have been given access to postcode of residence and date of each NHS GP registration since 1 January 2000.  This provides users with a means of locating their SLS sample continuously rather than only once every 10 years at the time of the censuses.

Besides projects primarily interested in internal migration, these data will be also useful to those investigating how the local environment affects outcomes, such as the recent project which looked at proximity to green space, forests and health services. The length of time spent at each address could be incorporated into analyses, or location might be explored in relation to wider policy measures or events such as the economic recession.

An early test dataset was supplied to project 2016_003 ‘Economic change and internal population dynamics: an innovative study of new residential mobilities in Scotland’. Results from these analyses have been presented at several seminars and conferences (see list at the bottom of the project page) and there are plans to publish papers.

The online data dictionary has now been updated with Table E10 which contains the raw data and some derived variables. Although many of these cannot be accessed by researchers due to the risk of disclosure (marked as restriction level 2), we are in the process of producing further derived variables such as flags, which users can access. We will soon produce a working paper which will document the data sources and processing of the data, describe the variables in table E10, compare the enumeration postcodes with the postcodes recorded in the NHS data, and provide other information that will be helpful when using and interpreting these data.

For further information see this blog post or contact SLS-DSU at sls@lscs.ac.uk.

ADRN conference 2017 – CALLS Hub strand

As our previous post demonstrates, the UK Administrative Data Research Network Annual Research Conference held on 1-2 June 2017 in Edinburgh provided a great showcase for research from the ONS LS, NILS and SLS studies. The conference included a series of sessions sponsored by CALLS Hub, promoting the use of census longitudinal studies and/or population linkage studies to contribute to the substantive themes of health/mortality inequality or migration. Here we round up the excellent presentations given in those sessions.

Ania Zylbersztejn: “Comparison of under-5 mortality in England and in Sweden using electronic birth cohorts from administrative linked data” – abstract and slides

Session 2G – Health inequalities

Sarah Curtis: “Long term illness and reported mental health conditions during recession: exploring evidence from the Scottish Longitudinal Study” – abstract

Jonathan Minton: “Profiling, benchmarking and exploring Age- Period-Cohort patterns in mortality in the Affluent World: examples from Scotland and beyond” – abstract and slides

Genevieve Cezard: “Mortality and ethnicity: minorities fare better than the White Scottish majority in the Scottish Health and Ethnicity Linkage Study (SHELS)” – abstract and slides

Session 3G – Internal migration

Annemarie Ernsten: “How can we better understand internal migration?” – abstract

Brian Foley: “Measuring Internal Migration: Comparing Census and Administrative Data” – abstract and slides

Session 4G – Health & migration (full video below)

Anne Kouvonen: “All-cause mortality by income level in working- age migrants and the majority settled population of Finland: a follow-up from 2001 to 2014” – abstract and video

Kishan Patel: “How well does registry data answer questions about migrant mental health? An analysis of author concerns from a scoping review” – abstract and video

Frances Darlington-Pollock: “The move, the person, or the area? Exploring risk of Cardiovascular Disease in New Zealand” – abstract and video

 

In addition, CALLS Hub were please to sponsor one of the conference Keynote speakers, Prof Johan Mackenbach, Professor of Public Health and chair of the Dept of Public Health at the Erasmus MC in the Netherlands:

Health inequalities in Europe. New insights from comparative studies

Abstract Socioeconomic inequalities in mortality are present in all European countries, but their magnitude and development over time is highly variable. In a series of on-going comparative studies we exploit these variations to identify the macro- and micro-level determinants of these mortality inequalities. In my presentation I will summarize the results of these studies, and relate our findings to current insights into the explanation of health inequalities in modern welfare states.

CALLS Hub/UK Data Service Webinar recording now available

Fiona Cox, CALLS Hub

Fiona Cox of CALLS Hub recently took part in a joint webinar with the UK Data Service on ‘Flexible individual-level data from the Census: Census micro data and longitudinal studies’, introducing the census-based longitudinal studies (ONS LS, NILS and SLS).

Conventional census outputs take the form of counts of persons, households or other units with particular characteristics. Census microdata, on the other hand, is a flexible form of data which provides a wide range of characteristics for large samples of anonymous census respondents. The data look a lot like the sort of data you would get if you conducted a survey yourself, however they have additional interesting features, most notably that they have unusually large sample sizes.

This introductory webinar discussed the two types of census microdata available for researchers to use:

  • Cross-sectional census microdata (known simply as ‘census microdata’ or samples of anonymised records) which take samples of data from individuals at one point in time, to allow comparisons between groups
  • Longitudinal census microdata held in datasets which link census records over time with other key records such as those from birth and death registrations

We describe some of the key features of the data, show how they can be used in research and explain how users can access the data.

New 1936 Birth Cohort Study

Zengyi Huang, SLS-DSU

The SLS Birth Cohort of 1936 (SLSBC1936) is now available to external researchers. This cohort is structured around the existing SLS. We took the SLS birth date sample from the Scottish Mental Survey of 1947 (a cognitive ability test that included almost all Scottish children born in 1936) and linked it to the 1939 National Register, the NHS Central Register and the SLS. The outcome of the project is a powerful life-course dataset containing information from childhood to old age.

A new SLS Technical Working Paper 7: ‘The Scottish Longitudinal Study 1936 Birth Cohort’ describes the methodology used in creating the SLSBC1936, the quality of linkage and the data included in this cohort. A short description of this data linkage project can be found on the poster: The creation of an administration data based 1936 Birth Cohort Study.

The SLSBC1936 is a general-purpose resource, which is available for researchers via the SLS administration. Anyone interesting in accessing this dataset should contact the SLS-DSU at sls@lscs.ac.uk.
