Professors Jonathan Gershuny and Oriel Sullivan presented at the launch of the new Economic Statistics Centre of Excellence (ESCoE) funded by the Office of National Statistics on 12th December 2022. They discussed their contribution to the project: "The ESCoE time-use programme: Time-use survey requirements for National Income accounting".

CTUR are making accessible programmes in STATA to help researchers analyse two of our key surveys - the Multinational Time Use Study (MTUS) and Covid-19 time use data series. 

Using a unique representative online time use diary survey, we examine the UK population's behaviour both before, and at five key phases during, the COVID-19 pandemic. A main focus of our analysis is which of the significant changes in activities associated with the pandemic survived the government-defined end of most restrictions on `freedom day' (July 19th 2021). Our data (N7,000 diary days) includes a baseline pre-pandemic survey, conducted in 2016, followed by five subsequent waves coinciding with key moments of pandemic restrictions, including all three lockdowns and two periods of relaxation of restrictions between lockdowns and after the final lockdown.

Using the original CaDDI instrument we collected 5 waves of time use diary data across the pandemic period in the UK, including during 3 'lockdowns' and 2 periods of relaxation of restrictions, plus a 2016 baseline (data available from the UKDS core collection, study number 8741).  

Since then, inspired by the 'contact' diaries used for modelling purposes by epidemiologists, we have designed a version of the CaDDI which includes more information on crowding while doing particular activities, or in particular venues, and the age/sex and degree of contact with people respondents report as being 'with them' across their diary days.  The idea is to combine the detailed information on activities of the time use diary (as well as information on location and social interaction) with variables of interest in epidemiological studies in respect of crowding and social contact (as in the POLYMOD 'diary').

In 2016 CTUR developed an online time use diary; the Click and Drag Diary Instrument (CaDDI), collecting population-representative (quota sample) diary information from Dynata’s large international market research panel across 9 countries. We fielded the same instrument using the UK panel during the COVID-19 pandemic: in May-June 2020 during the first lockdown; in late August 2020 following the relaxation of social restrictions; in November 2020 during the second lockdown; in January 2021 during the third lockdown; and in August/September 2021 after the lifting of restrictions.  The data allows comparison of detailed accounts of population behaviour (activities, location and co-presence) across 3 lockdowns and 2 periods of the relaxation of restrictions.  The complete set of six surveys has now been harmonised and deposited with the UK Data Service archive.

A wide-ranging public debate surrounds how pandemic lockdown measures differentially
impacted individuals and which precise mechanisms – whether financial-, health-, or policydriven
– predominate in determining these effects. Using a nationally representative 24-hour
diary survey covering the first two years of the pandemic, we explore the mechanisms
underlying changes in well-being. We exploit the variation in the stringency of the social
restrictions implemented by the UK government during this period and use an event-study
methodology to net out the impact of social restrictions from other pandemic effects.

CTUR has been awarded a £1M grant from the ESRC for the project ‘Time Use Research for National Statistics (TURNS), grant reference: ES/V016644/1. The team will be deploying new technologies in the design of time use diary (TUD) surveys, which will contribute both to the development of a new continuous UK time use data collection strategy and to the construction of a consistent system of time-use based social indicators of population health, wealth and wellbeing. An innovative experimental programme for collecting TUD information through online, webapp-based, surveys will be used, and the TUD data collected will provide a new range of time-used based national-level economic and social indicators.

CTUR has just published an outreach audio book on the science communication channel, SciPod. It is based on their research paper, 'Using time use diaries to track changing behaviour across successive stages of Covid-19 social restrictions' published in PNAS.

Now including information on new survey data and links to publications in PNAS (‘Using time use diaries to track changing behavior across successive stages of COVID-19 social restrictions’) and PLOS ONE (‘A new perspective from time use research on the effects of lockdown on COVID-19 behavioral infection risk’).

We present analyses of 24-hour time use diary records of the UK populations activities, their social context and their location, collected in real time from four successive waves of representative UK samples, both before, and during, the current COVID-19 pandemic. We show changes in behavioral response to social restrictions at three time-points during the pandemic, including across two nationwide lockdowns.

Sleep, work, eat, leisure – at a high level most of us spend time on similar activities. But just how similar are the daily activities of people across the world? This is something worth considering, not just to serve our curiosity but because differences in the way we spend time give us meaningful perspectives on living conditions, economic opportunities and general well-being.

This study compares self-report diary records of specific days with objective records of the same day constructed from wearable camera and accelerometer evidence. Results strongly supports the use of diary methodology at both the aggregate (sample) and individual levels. It provides evidence that time-use data could be used to complement physical activity questionnaires for providing population-level estimates of physical activity. It also implies new opportunities for investigating techniques for calibrating metabolic equivalent of task (MET) attributions to daily activities using large-scale, population-representative time-use diary studies.    DOI: 10.1177/0081175019884591
