How demography and population science contribute to our understanding of this public health crisis and the confinement period:

Since the onset of the COVID-19 pandemic, the French Institute for Demographic Studies (INED) has been actively analyzing the impact of the crisis on different populations and societies in France and elsewhere in the world. INED researchers and technicians use a multidisciplinary approach in order to describe and better understand the impacts of this health crises on population groups. Seven research projects have been launched recently and have already produced first findings, knowledge that is being used in the design of public policy measures for controlling disease spread and accompanying populations during the crisis.


The COVID-19 health crisis has demanded an unprecedented response from national and international research, the aim being to obtain new knowledge that can be used in designing public policies for controlling disease spread and accompanying populations during the crisis. As a public research institution dedicated to population studies, INED has been drawing on its wide range of disciplines—demography, economics, history, sociology, anthropology, statistics, biology, and epidemiology—and resources to contribute answers to the many questions that have arisen about the impact of the pandemic on populations, French society, and societies across the world.

No effort has been spared in coordinating and facilitating this research, from setting up an internet platform that tracks daily COVID-19-related deaths to conducting surveys, taking part in a number of innovative research projects, and diffusing scientific publications. INED’s multidisciplinary approach is an invaluable means of acquiring precise, cross-sectional knowledge of the new problematics emerging in this unprecedented situation.

Projet Covid-HOSP : « Impact de la pandémie de COVID-19 sur la prise en charge médicale : Analyse des données médico-administratives »

L'épidémie de Covid-19 a profondément ébranlé le système de santé français dans un contexte déjà tendu.

L’objectif général de ce projet est d’évaluer, à partir des données du Système National des Données de Santé (SNDS), les conséquences directes et indirectes de l’épidémie (et/ou du confinement) sur la santé de la population.

Il s’agira de constituer des cohortes de patients atteints de certaines pathologies chroniques facilement repérables dans le SNDS (telles que les cancers solides, l’infection à VIH, la drépanocytose, la mucoviscidose, les dialyses rénales, le diabète, les pathologies psychiatriques, …) et, pour chacune de ces cohortes,

  • d’évaluer le recours et la consommation de soin, la morbidité et la mortalité (avant, pendant et après le 1er confinement) ;
  • de déterminer la fréquence des formes graves de Covid-19: admission en réanimation, mortalité intra-hospitalière et jusqu’à 60 jours post-admission ;
  • de mettre en évidence l’hétérogénéité de la population en identifiant les facteurs associés à la mortalité : sexe, âge, co-morbidités, catégories sociales (indice de défavorisation sociale de l’Insee), type de résidence (institution vs. ménage ordinaire), type d’emploi, lieu de naissance et zones géographiques.


Le projet est financé par le Ministère des Solidarités et de la Santé, dans le cadre du Programme de Recherche sur la Performance du Système de soins (PREPS).  

Les partenaires sont : le centre hospitalier d’Annecy-Genevois (Tristan Delory) ; l’Ined (Sophie Le Cœur, Myriam Khlat, Gil Bellis, Émilie Counil, Service Méthodes Statistiques); et l’Inserm UMR-S 1136 (Nathanaël Lapidus, Pierre-Yves Boëlle, Gilles Hejblum)

Demography of COVID-19 deaths

By creating a bilingual French-English internet platform providing international data on the demographics of deaths linked to the COVID-19 pandemic, INED has shown its excellence in making standardized data available to the scientific community and citizens at large. International comparisons are a key, integral component of INED-led research. A substantial labor of rationally organized, continuous data accumulation is what made it possible as early as April 2020 to begin studying mortality variations across a considerable number of countries in connection with respective national policies for combatting COVID-19; to assess the French situation from an international perspective; and to document death data collection methodologies in the countries involved.

Many countries took drastic, unprecedented measures to counter the COVID-19 pandemic. Within Europe, the first country to be hit, Italy, was also the first to respond by deciding to quarantine the main epidemic “hot spots,” decreeing a country-wide lockdown, and choosing to suspend all non-essential activities. The other European countries, with the exception of Sweden, instated a general lockdown with varyingly tight restrictions at some point between the March 5 and 23.

At the international level, policy measures have been both multiple and diverse (prohibition of large gatherings, closing of schools and public venues, border closings, population lockdowns, tracking people’s movements via their cell phones, and others); those policies have had repercussions on COVID-19 mortality dynamics. By taking into account demographics-based disparities in mortality, researchers have been able to develop the tools needed for rigorous assessment of the quality and comparability of all available data on deaths due to the virus. This preliminary work is crucial to precise analysis of trends and well-founded projections.

Currently, the platform provides mortality data on Austria, Belgium, Germany, Italy, the Netherlands, Norway, Portugal, South Korea, Spain, Sweden, Ukraine, the United Kingdom, and the United States. Data on other countries will be available soon.

Health, practices, relations, and social inequalities in France’s general population during the COVID-19 crisis - SAPRIS

The SAPRIS project is a longitudinal general population survey designed to identify the epidemiological and social issues of the coronavirus public health crisis in France. It draws on the following five existing national general population cohorts, comprising a total of over 200,000 persons: Constances;  Étude Familiale E3N-E4N;  ELFE (French Longitudinal Study from Birth);   Epipage2;  and NutriNet Santé. Participants will be questioned on the problems and issues implicated in the epidemic and the lock-down (confinement) measures in France. Research focuses include the incidence of COVID-19 symptoms and other health problems; whether or not people seek medical care; risk perception; the effects of infection prevention measures on daily life, social relations, and work; and trust in public and scientific recommendations. The impact of lock-down on children will also be studied, in terms of its effects on parent-child relations and leisure activities, particularly screen use; as well as home schooling conditions and children’s overall wellbeing in a situation of confinement. Study of childhood-related problematics will focus in particular on ELFE/Epipage cohort respondents.

This national survey will be conducted by a multidisciplinary group of researchers from INSERM (Institut National de la Santé et de la Recherche Médicale); INED; the CNRS; the Universities of Paris-Saclay, the Sorbonne, Sorbonne Paris-Nord and Paris Dauphine-PSL; the Caisse Nationale de Assurance Maladie (CNAM: the national health insurance fund), and INRAe (Institut National de Recherche pour l’Agriculture, l’Alimentation et l’Environnement).

[COVID-19 in skilled nursing care homes in France] (Qualitative, prospective, and multicenter study of COVID-19-related death and end-of-life in skilled nursing homes in France - COVIDEHPAD

The number of people who may be expected to end their lives in nursing care facilities during lockdown for sudden public health crises is likely to be particularly high and the experience particularly traumatizing. The Higher Education, Research and Innovation Ministry has requested the plateforme nationale pour la recherche sur la fin de vie (PNRFV) [national platform for end-of-life research] to develop a multicenter qualitative study that will describe, analyze, and help understand this lived experience and the practices of persons confronted with end-of-life situations and death in nursing homes during the COVID-19 epidemic in France, specifically during the period of lockdown (confinement) and transition to de-confinement.

Humanities and social science research professionals are conducting telephone interviews with nursing home professionals and, wherever possible, family members and residents.

The aim of the project is to use the findings to formulate recommendations and arrangements for improving end-of-life accompaniment in nursing homes during a public health crisis. It is also to improve our knowledge of end of life, the accompaniment of dying persons, and grieving processes under extraordinary temporal conditions.

Emmanuelle Cambois, Senior Researcher at INED, Sophie Pennec, Senior Researcher at INED and Jean-Marie Robine, Senior Researcher at INSERM and advisor to INED management in charge of ageing issues participate in the scientific council of this project.

Characterization of risk of serious covid19 infections and over-mortality in skilled nursing home in France - COVID-EHPAD

Summary of research: During the SARS-COV2 2020 pandemic, the lethality rate has been highest among subjects aged 80 or over, particularly those with underlying co-morbidities. Elderly subjects living in France’s EHPADs (Établissements pour Personnes Agées Dépendantes: skilled nursing care facilities) are therefore particularly vulnerable due to their individual and contextual characteristics (age, co-morbidities, collective living situation, access to treatment). Approximately 600,000 old and oldest-old subjects live in these facilities in France. The aims of the COVID-EHPAD research project are

  1. to determine over-mortality among subjects living in EHPADs during and after the epidemic;
  2. to determine the causes of death (the share related to COVID-19 and share not related);
  3. to determine the risk of serious SARS-COV-2 infection;
  4. to evaluate treatment during the epidemic of subjects living in EHPADS in the areas of i) care for COVID-19 and ii) care for other pathologies in the context of lockdown and hospital saturation.

The consortium of researchers involved is under development. Jean-Marie Robine will participate in this project.

Lockdown, living conditions, and inequalities - COCOVI

Housing situation has once again become a crucial dimension of our living conditions since much of our social activities are currently taking place in our living spaces.

The COCOVI project (Confinement, Conditions de vie et Inégalités) will analyze housing conditions and household life in France during the COVID-19 pandemic, measuring disparities before and during lockdown (confinement) between households of different social milieus, located in different geographical environments (rural, peri-urban, city center, single-family suburban, dense housing projects, etc.). Situational disparities may be due to changes in household composition and arrangements and/or temporary or definitive changes in residence and housing. 

The project will be run by researchers of INED’s “Housing, Spatial inequalities and Trajectories” research unit and will draw on three complementary types of data:

  • in-depth interviews with households confined in different types of areas that are also sites of former ethnographic field studies;
  • secondary processing of public statistics general population surveys (notably the “Logement” [Housing] survey);
  • an ad hoc questionnaire to be taken by approximately 1000 persons constituting a representative sample of France’s adult population. The questionnaire survey will be conducted jointly with a group of researchers from COCONEL (Coronavirus et confinement: Enquête Longitudinal), INSERM (Institut National de la Santé et de la Recherche Médicale), IRD (Institut de Recherche sur le Développement), the ANR (Agence Nationale de la Recherche) and the IFOP opinion poll institute: Patrick Peretti-Watel (scientific coordinator), Valérie Seror, Sébastien Cortaredona, Odile Launay, Jocelyn Raude, Pierre Verger (research consortium), François Beck, Stéphane Legleye, Olivier L’Haridon, Jeremy Ward (Steering Committee).

First Results

This project includes a survey questionnaire (the COCONEL-1 “Housing and living conditions” survey) of the adult French population designed for the purpose of a first overall assessment of the effects of lockdown in France (confinement). The survey inquired into living spaces and places, income, work and working at home, children and family relations, social contacts and the feeling of isolation, young people’s experience, and family solidarity during the pandemic. The first findings have revealed major changes in daily living conditions and housing uses and inhabiting modes. The survey has also shown how confinement widened existing social gaps in French society, to the detriment of women, young people, and people of relatively modest material and financial means. Interruption or loss of paid work, fall in income, fear for the future, feeling of isolation—all these indicators worsened cumulatively, deepening a range of existing inequalities.

Knowing the population’s immune status to guide public decision-making - EpiCOV

One aim of the EpiCOV project is to produce a precise map of the French population’s immune status, health, and living conditions along with the social inequalities characterizing these three parameters; the other is to follow the dynamic of the epidemic in France over the short, medium, and long term. A large-scale epidemic surveillance cohort, statistically representative at the département level, has been set up in record time and will be particularly useful in modeling the epidemic.

INED is a partner in this project, to be run by INSERM, the Health and Solidarity Ministry’s DREES department (Direction de la Recherché, des Études, de l’Évaluation et des Statistiques), together with other partners (INSEE, Santé Publique France, the CNRS, and the Université Paris-Saclay).

The project is based on a major national survey of a representative sample of over 200,000 persons aged 15 or over residing across France (metropolitan France, Martinique, Guadeloupe and Reunion) and randomly selected by INSEE. Respondents have been asked to fill out a 20 to 30-minute questionnaire (either on line or by telephone); in parallel, and subject to individuals’ consent, biological samples from 100,000 of the same respondents will be tested to determine if they have been in contact with the virus. Responses were treated confidentially by the research teams, in compliance with the regulations currently in effect (Statistics confidentiality, CNIL [national data protection commission] data protection regulations).

This project is carried for Ined by Elise de la Rochebrochard, Senior Researcher.

Projet TELEGENRE - Les effets différenciés du télétravail selon le genre

Le télétravail a connu un essor sans précédent durant la crise liée à la pandémie COVID-19. Il a eu un effet protecteur pour la santé et a permis aux personnes concernées de maintenir leur emploi, mais le contexte spécifique de sa mise en place a pu exacerber les effets potentiellement négatifs du télétravail sur le bien-être identifiés dans la littérature, notamment pour les femmes du fait de l’inégale répartition des responsabilités domestiques et parentales. Notre hypothèse est que cette forme d’organisation du travail, a priori neutre du point de vue du genre, a des effets différenciés chez les hommes et les femmes. Nous postulons également une hétérogénéité des effets selon la situation familiale et le mode d’exercice du télétravail. L’objectif de ce projet est de comprendre l’effet du télétravail sur les inégalités de genre dans l’exercice du travail, les organisations familiales, le bien-être et la santé mentale. Il repose sur l’analyse de deux grandes enquêtes représentatives en population générale, « Épidémiologie et conditions de vie » (EpiCoV) et « enquête sur le vécu du travail et du chômage pendant la crise sanitaire » (Tracov).

Health and environmental crises: Humanities, social sciences, public health (HS3P-CriSE).

The COVID-19 crisis has shaken up societies and raised new research questions. To avoid research redundancies or overlap and ensure that the most important questions are handled, it is crucial to coordinate research activities. It is for this purpose that INED has joined forces with the CNRS and INSERM’s HS3P-CriSE working group, whose aim is to develop research structuring initiatives in the social and human sciences and public health in connection with COVID-19, infectious diseases generally, and today’s major health and environmental crises. The group is designed to play a complementary role for existing, currently hatching, or projected research actions and initiatives, particularly calls for projects, by proposing scientific research programming plans. The focus will be on the situation in France; also and more widely on other countries, with particular emphasis on global South countries.
