  • About INED

    The French Institute for Demographic Studies or INED, is a public research institute specialized in population studies that works in partnership with the academic and research communities at national and international levels.

    • Who we are

      INED was founded in 1945, and in 1986 it acquired the status of an Etablissement Public à Caractère Scientifique et Technologique (EPST), meaning that it is under joint administrative supervision of the ministries of research and social affairs. The Institute’s missions are to study the populations of France and other countries, to ensure wide dissemination of the knowledge thereby acquired, and to provide training in research through research. INED’s approach to demography is resolutely open and interdisciplinary, implicating a wide range of disciplines including economics, history, geography, sociology, anthropology, biology and epidemiology. With its research units, the Institute promotes communication and exchange within the scientific community and between researchers and the general public while conducting numerous European and international research projects.

      • Our history
      • Our remit

        In 1986, INED became one of France’s eight public scientific and technical institutions (EPST), alongside CNRS, INSERM, INRA and the IRD (Institut de Recherche pour le Développement). The Institute’s overall missions are to study all aspects of population, to provide training in and through research, to keep the government, public authorities and general public informed about demographic questions and to disseminate French demographic research internationally.

        • Missions and activities
        • Research Evaluation
      • INED organization

        Nearly 250 people, including 50 tenured, or permanent, researchers and more than 40 doctoral students, work at INED; there are also 40 associate researchers. The Institute has 10 research units, a mixed research unit and 5 research support services, including the Statistical Methods and Surveys departments

      With its strong interdisciplinarity and its status as a reference in demography, INED is an active contributor to the development of French research.
      The Institute is one of the driving forces of major current research projects, such as the Campus Condorcet, which is transforming the landscape of the humanities and social sciences in the Paris region. And with its leading role in the iPOPs research programme (Individuals, Population, Societies), awarded the status of Laboratory of Excellence (Labex) by the state, the Institute has been able to put population questions at the centre of France’s “Investments for the Future” national research funding programme.
      As a member of the new scientific cooperation networks, INED is consolidating its long-standing ties iwith universities, grandes écoles and other research institutes.

      • Other research Institutes
    • International Policy

      One distinguishing characteristic of INED is its ability to conduct research studies that cover not just France but a large part of the world. The international scope of the Institute may be seen in its many partnerships with institutions abroad and its active role in the world scientific community.

      • International cooperation

        INED researchers have a long tradition of collaboration with their counterparts throughout the world. To facilitate scientific cooperation, the Institute has established numerous partnerships and is involved in all the international population research networks; it also supports the mobility of its doctoral students and researchers.

  • Research

    Research at INED is organized around multidisciplinary and topic-focused teams made up of its own permanent researchers and associated researchers. Institute research units host doctoral students and post-docs for training in and through research. Over 70 multi-annual projects are under way. For some, INED designs and carries out its own surveys—one of its specificities. Collected data are then made available to the scientific community.

    • Surveys

      INED designs and carries out its own surveys. The data thus collected are accessible to the entire scientific community. The Institute has its own survey office, which defines sampling methods, assists in designing questionnaires and drawing up data collection protocols, and adjusts statistical samples. It is also in charge of making anonymized data available to others. INED’s survey catalogue and a description of the projects in progress may be consulted on line.

  • Resources, Methods

    INED makes a vast body of resources on population available to website users, including the INED library, open to all and accessible on line; and presentations of statistical analysis and survey methods.

    • Statistical Methodology

      Research relies on a wide range of statistical analysis methods to process survey data and to describe and model demographic events and phenomena on the basis of that data. Alongside classic methods such as data analysis and logistic regression, several other methods have come to the fore in the last 30 years.

    • Survey Methodology

      Each survey is specific but all surveys include a number of requisite steps and phases. Important factors to be taken into account from the outset include survey protocol, sampling frame, budget, regulations, questionnaire testing, data file compilation, and quality assessment. INED’s Surveys Department handles most of the data collection procedures involved in INED research projects. It may assist with data production throughout the process or provide help on particular survey phases only.

      • Procedures
      • Methodological choices

        Every INED survey is designed to investigate a particular research question or set of questions. INED surveys are “custom-made” and in many cases highly innovative. Methodological choices are therefore a key phase of the research. The time required to prepare the survey, design questions, conduct and assess pilot surveys and, later, to evaluate the quality of the data collected must not be underestimated.

  • Publications

    INED Publications has been in existence since the Institute’s founding in 1945, consistent with one of its fundamental missions: to disseminate scientific knowledge. INED Publications reflects and enacts the Institute’s commitment to multi-disciplinarity in demographic research by diffusing and promoting scientific production and survey results and findings to a diverse audience, thereby making solid scientific expertise and knowledge available for public debate on major social issues. Recently, the Open Archive has widened diffusion of free-access published materials while ensuring the continued preservation of INED researchers’ studies.

    • Data

      All about population in Figures: tables on the French and world population and access to several online databases.

      • France

        The latest data on the population of metropolitan France (structure and trends) are given in a series of tables. They are based on data published regularly by INSEE and on INED estimates and projections. More complete datasets dating back to earlier years can also be downloaded in CSV format.

        • Evolution of population

          The tables for “All of France” bring together data for metropolitan France and the four overseas départements (DOMs). These figures do not include Mayotte, which became the fifth DOM on 31 March 2011, or the overseas territories and collectivities (New Caledonia, French Polynesia, Saint Barthélémy, Saint Martin, Saint Pierre and Miquelon, Wallis and Futuna). INSEE includes the DOMs in its annual demographic overview and in most of the tables in its detailed annual study of the demographic situation in France.

          • Total population
          • Demography of overseas départements
          • Projections
        • Population structure

          The population of France by sex and age is estimated by INSEE each year. A provisional estimate is first issued and final figures are published at a later date. Censuses are conducted in certain years to enumerate the population. The population estimates are adjusted on the basis of census data, for the whole of France and for the different départements and regions.

          • Population Pyramid
          • Population by sex and age on January 1st
          • Population by age
          • Centenarians
          • Population by region and department
          • Municipalities
        • Population change

          The population changes from one year to the next. Natural change is the difference between births and deaths, and can be determined precisely from vital records. Net migration is the difference between the number of immigrants and the number of emigrants. It is estimated on the basis of available statistics. Adjustments are sometimes made to establish overall consistency between census population figures and inter-census estimates of population change. To estimate its relative scale, population change is often expressed in relation to the mean population of a given year. Rates of birth, death, natural increase and total variation are obtained in this way.

          • Births, deaths, migrations
          • Fertility rates, mortality rates, natural increase
        • Births, fertility

          Registered births are recorded in statistical bulletins which provide a rich source of information. Births are counted on the basis of many different characteristics: parents’ marital status and nationality, sex of the child, twin births, etc. Information on the mother’s age is used to calculate annual fertility indicators, such as the total fertility rate expressed as a total number of children per woman. Completed cohort fertility is also calculated every year. For example, women born in 1970 were 34 years old in 2004. We know how many children they have had before age 34 and we can estimate how many children they will have during their reproductive life.

          • Total births by sex
          • Births outside marriage
          • Births by parents’ place of birth
          • Multiple births
          • Changes in fertility
          • Mean age at maternity
          • Cohort fertility
        • Abortion, contraception

          Fertility can be controlled by means of contraception and induced abortion. Information on contraceptive practice in France is obtained through surveys conducted regularly by INED since 1978 among the entire female population. The number of induced abortions is estimated on the basis of abortion notifications and hospital statistics. INED is responsible for publication of abortion statistics.

          • Abortions
          • Contraception
        • Marriages, divorces, Civil Unions (Pacs)

          Marriage registers provide a rich source of information on marriage practices: number of marriages, previous marital status and nationality of spouses, etc. Statistics on divorces and civil unions (PACS) are supplied by the Ministry of Justice.

          • Marriage and nuptiality
          • First Marriages and Remarriages
          • Cohort nuptiality
          • Mixed marriages
          • Divorces
          • Civil unions (PACS)
        • Couples, households, families

          The first task in a population census is to enumerate dwellings. Persons living in the same dwelling form a household, so each household comprises all the persons living in a single dwelling. According to the census definitions, a household may comprise one or more families. A family is a group of persons comprising a couple with no children, a couple with children, or one adult and his/her children.

          • Couples
          • Household size
          • Household structure
          • Structure of families with child(ren)
          • Number of child(ren) in the family
          • Children of families
        • Deaths, causes of mortality

          Death registers provide a means to measure variations in mortality. Deaths by sex and age are used to construct life tables which give life expectancy at birth, i.e. the number of years a newborn infant would live if prevailing patterns of mortality at the time of its birth were to stay the same throughout its life. The mortality of children under the age of one year is also specifically calculated. When a person dies, a doctor records the cause of death on a death certificate which is sent to INSERM where all causes of death are coded.

        • Immigration flows

          On this page INED presents an overview of the annual number of entries of foreign citizens who immigrate legally and permanently to France. Our calculations are based on data from the central database of residence permits (AGDREF) of the Ministry of the Interior. These immigration flow statistics consider only foreign nationals who are required to obtain a residence permit, and thus exclude citizens of the European Union. In line with international recommendations, only permits valid for more than one year are taken into account.

          • Immigration flows by sex and age in 2017
          • Immigration flows by continent of origin
          • Immigration flows by reasons for admission
        • Immigrants and immigrant descendants

          Population censuses provide an opportunity to count the number of inhabitants who were born outside France. Among foreign-born inhabitants, a distinction is generally made between persons born with French nationality and immigrants, who are born with a different nationality. Inhabitants are distinguished by their nationality, i.e. French or foreign and, among French citizens, those who were born French and those who have been naturalized. The census provides information on current nationality and nationality at birth. Foreigners and immigrants form two different categories. Immigrants "born abroad as a foreign national" may still be foreigners at the time of the census or may have become French. Foreigners, for their part, may have been born abroad (in which case they are immigrants) or in France (in which case they are not immigrants).

      • European and developed countries

        This section provides data tables on populations, births and deaths in Europe and in developed countries. It also includes indicators of population change (birth and death rates) and the two main demographic indicators: the total fertility rate and life expectancy at birth.
