Family is a major driver of migration. Family migration is the term used to categorize the migration of people who migrate due to new or established family ties, and it encompasses several sub-categories: reunification with a family member who migrated earlier (a person with subsidiary protection is also entitled to (re)unite with family members); family accompanying a principal migrant; marriage between an immigrant and a citizen; marriage between an immigrant and a foreigner living abroad; and international adoptions.
In general, data on family migration are sparse and family (re)unification programmes are the predominant means to collect such data. These programmes were developed to ensure the right to a family enshrined in Article 16 of the Universal Declaration on Human Rights. Data on family migration are based on visas and residence permits issued to family members, as well as population registers.

Family migration as a general concept covers family reunification, family formation, accompanying family members of workers, and the migration of a family unit as a whole. The following are key terms and concepts.
Family reunification/reunion “is a process whereby family members separated through forced or voluntary migration regroup in a country other than the one of their origin” (IOM, 2011).
Family formation refers to the situation in which “a resident, national or foreigner, marries a foreigner and sponsors that individual for admission or for status change” (OECD, 2017).
Accompanying family “means family members [who] are admitted together with the principal migrant” (OECD, 2017).
International adoption is where a “resident, national or foreigner, adopts a child of foreign nationality resident abroad” (OECD, 2017).
Principal/primary/main applicant “is the person who applies for refugee or other immigration status. General international practice is that dependents (usually a spouse and any minor children) are considered derivative applicants and receive the same status afforded to the principal applicant” (IOM, 2011).
Dependent, in general use, “is one who relies on another for support. In the migration context, a spouse and minor children are generally considered ‘dependents’, even if the spouse is not financially dependent” (IOM, 2011).
Members of the family are “persons married to migrant workers or having with them a relationship that, according to applicable law, produces effects equivalent to marriage, as well as their dependent children and other dependent persons who are recognized as members of the family by applicable legislation or applicable bilateral or multilateral agreements between the States concerned” (IOM, 2011).
The scope of family reunification depends on national law. For example, some countries may include same-sex partners (registered or married) or unmarried partners, whereas others may not (European Migration Network, 2017). Thus, the definition of whom family members can comprise varies across countries.
Transnational families “are families who live apart, but who create and retain a ‘sense of collective welfare and unity, in short “familyhood,” even across national borders’” (Bryceson and Vuorela, 2002 in ACP, 2012).
Data on family migration in developing countries are either sparse or scattered, due to a lack of capacity or political will to collect data (see Data strengths and limitations below). However, family migration data is available for countries in the Organization for Economic Co-operation and Development (OECD) area, where, in 2017, family migration comprised 40 per cent - around 2 million migrants - of the total permanent migration in these countries (OECD, 2019). The number of family migrants remained stable in relative terms, but it increased in absolute numbers, more specifically from 1.8 million in 2016 to 2 million in 2017 (ibid.).
In 2017, the number of people migrating for family reasons, for family reunification or formation, increased by 11 percent to reach 2 million (OECD, 2019). The number of accompanying family members comprised 253,000 in 2017 (ibid).
The United States accounted for 43 per cent (748,000) of total family migration in OECD countries, which represents a 6 per cent drop in comparison to 2016 (OECD, 2019). In 2017, the flow of family migration has increased in such OECD countries as Italy, Germany, Spain, the United Kingdom and Portugal. Sweden recorded the strongest increase in family migration which amounted to 23 per cent. A strong fall in migration for family reasons was observed in New Zealand, besides the United States.
From 2014 until 2017, family migration was increasing in the majority of countries in the OECD area (OECD, 2017). However, family migration flows declined due to the shrinking of family reunification programmes in some OECD countries (OECD, 2019). Nonetheless, no country has established outright restrictions on family migration, although there have been recent deliberations in the United States regarding the possible ending of family-based migration (MPI, 2017).
Despite the existing legal instruments and programmes that ensure the right to a family life?, in 2012, the proportion of non-EU nationals in the European Union not living with their spouses or partners reached 5-7 per cent of those who live together, a much higher level of "living apart together" than for EU nationals (MIPEX, 2014).
Both flow and stock data on family migration are predominantly based on national administrative records. Family migration flow data are derived from entry clearance visas (ECV), first residence permits or population registers for family reasons. Stock data on family migration are based on stock of permits or stock of long-term residents. Some countries combine administrative and specific survey data on family migration, e.g. the international passenger survey (IPS), to augment the quality of data. Data on family migration are also collected via such sample surveys as annual population surveys, labour force surveys or income and living conditions surveys. Data collected via individual surveys or ethnographic studies enable collection of granular data to better understand the transnational family arrangements across borders.
The following are databases that consolidate flow or stock data on family migration:
Organization for Economic Co-operation and Development (OECD) consolidates inflow data on family, work and humanitarian migration. The OECD dataset on permanent immigrant inflows is derived from Eurostat (see below) and non-EU countries. The dataset is updated on a biannual basis.
OECD also produces statistics on permanent migration inflows in the OECD area, based on the aforementioned dataset, which are presented in the OECD’s International Migration Outlook. The report also presents estimates on family migration for OECD countries and is updated annually.
Eurostat, the Statistical Office of the European Union compiles data on asylum and managed migration primarily based on administrative sources provided by EU Member States’ national statistical offices, interior ministries or related immigration agencies, as well as by Iceland, Norway, Liechtenstein and Switzerland. The database on asylum and managed migration presents the following datasets:
- First permits issued for family reunification with a beneficiary of protection status
- First permits issued for family reasons, by reason, length of validity and citizenship
- Change of immigration status permits, by reason and citizenship
- Admitted family members of EU Blue Card holders, by type of decision and citizenship
- EU Blue Card holders and family members, by member state of previous residence
- Permits valid at the end of the year for family reunification with a beneficiary of protection status
The aforementioned datasets are disaggregated by sex and age. Data are predominantly updated on an annual basis.
The Migrant Integration Policy Index (MIPEX) measures migrant integration policies, including those who come for family reasons. There are currently 8 policy indicators that measure policies. In 2011/2, MIPEX conducted a survey to measure how easily immigrants can reunite with their family members. Data on family reunion are available for Australia, Canada, Iceland, Japan, New Zealand, Norway, South Korea, Switzerland, the USA, the EU Member States and Turkey. Data on family reunion for 2011/2 were last updated in 2014.Back to top
Data strengths & limitations
In light of the current political climate, in which family-based migration in some countries is discussed in connection to irregular migration or in the context of it being a burden to the social system of a host country, granular data on family migration are of special importance to deconstruct these particular myths with data-driven deliberations.
The existing data sources on family migration are valuable baselines, but further enhancement in data collection and harmonization methodologies is essential. In pursuit of these improvements there are limitations that hinder the process, including the following:
There is no global comparable database on family migration, which covers all countries and areas of the world. This is due to a lack of data from most developing countries. Data are missing due to a lack of capacity to collect, process and disseminate data on family migration in these countries. Even when data are available, it is often challenging to integrate and harmonize datasets of diverse origins because of inconsistent methodological frameworks.
There is still little known about the recent dynamics of family migration and about the impact of migration policies in shaping it (OECD, 2017). This is despite the availability of family migration data in some regions of the world. Moreover, the evidence-base regarding the socio-economic demographic characteristics of family migration in some countries has not been updated. For example, in the United States, the most recent surveys on socio-demographic characteristics of family migrants date from the 2000s (ibid.).
Statistics derived from administrative records do not portray the complete picture of the flow of family migrants (GMG 2017). This is because, although administrative data sources enable the production of estimates on family migration, statistics derived from population registers and issuance of residence permits refer to administrative records rather than people (ibid.). For example, if the permit granted to the head of a family covers her or his dependents, the number of issued residence permits over a year will not be equivalent to the number of family migrants. Some countries are undertaking initiatives to tackle this issue. They tend to combine different data types, namely survey data and administrative records, to improve the quality of migration data.
Data on transnational familyhood are scarce. Despite the growing importance of this type of family arrangement in recent years, there is still limited knowledge on the scale and dynamics of this type of family arrangement in a migration context. Evidence-based policy is needed to ensure the migration of a family member does not need to lead to those left behind suffering.
Data on family emigration are currently incomplete because of the most countries’ limited capacity or lack of political will to collect data on family emigration. Thus, policy makers lack a sufficient evidence base to facilitate family emigration processes.
