Acquisition of citizenship statistics

Data extracted in May 2015. Most recent data: Further Eurostat information, Main tables and Database. Planned article update: May 2016.

This article presents recent statistics on the acquisition of citizenship in the European Union (EU).

In 2013, 984 800 people obtained citizenship of an EU-28 Member State, an increase of 20 % compared with 2012; More people had acquired the citizenship of an EU Member State than in any other year during the period from 2002 to 2012. The main contribution to the increase at EU level came from Spain (+131 700), followed by Italy (+35 300), the United Kingdom (+13 600) and Greece (+9 200). The increase in Spain, however, is a consequence of a change in the source of information, concept and time reference.

Most new citizenships in 2013 were granted by Spain (225 800 or 23 %), the United Kingdom (207 500 or 21 %), Germany (115 100 or 12 %), Italy (100 700 or 10 %) and France (97 300 or 10 %).

Of those acquiring citizenship of an EU-28 Member State, 89 % had previously been citizens of non-EU countries. Of these, citizens of Morocco made up the highest numbers, followed by citizens of India, Turkey, Colombia, Albania and Ecuador.

Main statistical findings

EU-28 Member States granted citizenship to around 984 800 persons in 2013

In 2013, 984 800 people obtained citizenship of an EU-28 Member State, an increase of 20 % compared with 2012. This was mainly caused by the increases in absolute terms in Spain (131 700 more persons were granted Spanish citizenship compared with 2012), followed by Italy (35 300), the United Kingdom (13 600) and Greece (9 200). By contrast, the largest decreases in absolute terms were observed in Hungary (9 200 less persons were granted Hungarian citizenship compared with 2012) and Netherlands (5 000 less).

The top five citizenship-granting countries accounted for 76 % of new citizenships granted in the EU in 2013: Spain (225 800 or 23 %), followed by the United Kingdom (207 500 or 21 %), Germany (115 100 or 12 %), Italy (100  700 or 10 %) and France (97 300 or 10 %).

The highest relative increases were seen in Spain (up by 140 %), Italy (up by 54 %) and Greece (up by 45 %). By contrast, the highest relative decreases of more than 50 % were recorded in Hungary (down by 50 %), Denmark (down by 51 %) and Bulgaria (down by 54 %).

In relation to the population, the highest number of citizenships were granted by Ireland (5.3 per thousand persons) followed by Sweden (5.2), Spain (4.8) and Luxembourg (4.7).

An indicator commonly used to measure the effect of national policies on citizenship is the "naturalisation rate" or ratio of the total number of citizenships granted over the stock of non-national population in a country at the beginning of the year. It is important to note that changes in naturalisation rates can also be attributed to changes in the non-national population and in the way the non-national population is measured (see Data sources and availability.

In 2013, in the EU-28 as a whole, 2.9 per hundred non-national citizens were granted citizenship. The country with the highest naturalisation rate was Sweden (7.6 per hundred), followed by Hungary (6.5) and Portugal (5.9). The lowest naturalisation rates were found in Slovakia (0.3). Other countries with naturalisation rates under 1.0 were Denmark (0.5), the Czech Republic (0.5), Estonia (0.7), Austria (0.7), Lithuania (0.8), Cyprus (0.9) and Latvia (1.0).

Of the five EU-28 countries that granted the most citizenships, the rate was above the EU-28 average in Spain (4.5) and the United Kingdom (4.2). The rates were below the EU-28 average in France (2.4), Italy (2.3) and Germany (1.5).

A third of new EU citizens were Moroccans, Indians, Turks, Colombians, Albanians and Ecuadorians

About 89 % of those who acquired citizenship of an EU-28 Member State in 2013 were previously citizens of a non-EU country. This means that 871 300 non-EU-28 citizens residing in the EU-28 acquired an EU citizenship in 2013, a 21 % increase with respect to 2012. These new EU-28 citizens were mainly from Africa (26 % of the total number of citizenships acquired), Asia (23 %), North and South America (22 %) and Europe (outside of the EU-28, 17 %). Citizens of EU-28 Member States who acquired citizenship of another EU-28 Member State amounted to 98 500 persons, thus accounting for 10 % of the total.

Only in Luxembourg and Hungary were the majority of new citizenships granted to citizens of another EU Member State. In Hungary, citizenship was granted mostly to Romanians; in Luxembourg to citizens of Portugal, Italy, France, Belgium and Germany.

Viewed in terms of original citizenship, as in previous years, the largest groups were Moroccans (86 500, or 8.8 %), followed by Indians (48 300, or 4.9 %), Turks (46 500, or 4.7 %), Colombians (42 000, or 4.3 %), Albanians (41 700, or 4.2 %) and Ecuadorians (40 400, or 4.1 %). The majority of Moroccans acquired citizenship of Spain (35 %), Italy (29 %) and France (19 %), while a large majority of Indians (75 %) received British citizenship and more than half of the Turks received German citizenship (60 %). The overwhelming majority of Colombians (93 %) and Ecuadorians (95 %) were granted citizenship in Spain and more than half of the Albanians received Greek citizenship (62 %).

Romanians were the ninth largest citizenship of origin in 2013, decreasing by 8.7 % (from 25 200 in 2012 to 23 000 in 2013). Grants of citizenship declined for one of the highest six citizenships of origin: for Turks by 17 % and increased for five of the highest six citizenships of origin: for Moroccans by 42 %, for Indians by 31 %, for Colombians by 117 %, for Albanians by 64 % and for Ecuadorians by 39 %.

In addition to Romania, among the thirty main countries of previous citizenship there is another EU-28 country whose citizens acquired citizenship of another EU country: Poland. In absolute terms, most Romanians acquiring citizenship became citizens of Hungary (7 000 persons) and Italy (4 400 persons), more than half of the acquisitions of citizenship by Poles were in the United Kingdom (6 100 persons) and Germany (5 500).

Half of those changing citizenship were aged 32 or less

The distribution by gender shows a slight predominance of women (52 % against 48 % men). Acquisitions of citizenship by women outnumbered acquisitions by men in all but four of Member States (Greece, Hungary, Romania and Slovenia). The highest proportions of citizenship acquisitions by women were recorded in the Lithuania (59 %), Slovakia (57 %) and the Czech Republic (56 %). The country with the highest share of acquisitions by men was Romania (57 %).

Observed by age, there are two distinct peaks in terms of the predominance of acquisitions by women: one in the age group 20-34 and another slight peak among those aged 50-64.

In 2013, the median age of persons acquiring citizenship in the whole of the EU was 32. The Member State with the lowest median age was Estonia; half of its new citizens were younger than 24. The highest median age (41) was in Lithuania. Age distribution varied from one Member State to another due to differences in citizenship legislation and age structure of the non-national population (see Data sources and availability). However, the common feature uniting all Member States was that most new citizenships were acquired by younger people, and that the numbers declined with age.

In 2013, more than a third of persons granted citizenship of an EU-28 country were younger than 25 years and nearly half aged 25 to 44, while those aged 55 or over accounted for less than 6 %.

The proportion of citizenship acquisitions by children was highest in France (33 %), Estonia and Denmark ( both 31 %) and lowest in Bulgaria (4.7 %). In Lithuania and Luxembourg, no children were granted citizenship.

Lithuania accounted for the highest share of grants of citizenship to persons aged 65 or older (13 %), followed by Greece (9.1 %). The lowest shares of elderly new citizens were recorded in Ireland (0.5 %), Austria and Estonia (both 0.6 %), Italy and Portugal(both 0.8 %), and Romania 0.9 %).

Data sources and availability

Data on acquisitions of citizenship are collected by Eurostat under the provisions of Article 3.1.(d) of Regulation 862/2007 on migration statistics, stating that: "Member States shall supply to the Commission (Eurostat) statistics on the numbers of (…) persons having their usual residence in the territory of the Member State and having acquired during the reference year the citizenship of the Member State and having formerly held the citizenship of another Member State or a third country or having formerly been stateless, disaggregated by age and sex, and by the former citizenship of the persons concerned and by whether the person was formerly stateless."

The collection of data on acquisition of citizenship is defined by Regulation 862/2007 and breakdowns and composition of the EU, EFTA and candidate countries groups are given in the implementing Regulation 351/2010.

The EU-28 aggregates for 2012, 2011 and 2010 include Romanian data for 2009.

Citizenship: the particular legal bond between an individual and his or her State, acquired by birth or naturalisation, whether by declaration, choice, marriage or other means according to the national legislation. International law does not provide detailed rules, but it recognises the competence of every state in cases like: spouses of citizens, minors adopted by citizens, descendants of citizens born abroad returning to the country of origin of their ancestors, etc. Countries differ considerably in terms of the conditions to be fulfilled to acquire citizenship: in general a period of legally registered residence is required, combined with other factors such as evidence of social and economic integration and knowledge of national languages. Different conditions may apply for persons who were born in the country concerned (jus soli), or who have parents or other relatives with that country's citizenship (jus sanguinis).

Detailed information on the different modes of acquisition of citizenship in force in different countries can be found at the EUDO Citizenship website.

The category recognised non-citizen is particularly relevant in the Baltic States.

Countries revising the population series after the 2011 Census round were expected to send revised post-census results by age, sex and citizenship or country of birth to Eurostat for the whole intercensal period or shorter by the end of 2013. Eurostat has been informed of difficulties from the following countries to meet the deadline of 31 December 2013 for post-2011 census data transmission together with the following planned deadlines:

1) announcements: Germany (first half 2015);

These revisions of data will have an impact on the naturalisation rates.


Within the European Commission, the Directorate-General for Home Affairs is responsible for immigration policy. In 2005, the European Commission relaunched the debate on the need for a common set of rules for the admission of economic migrants with a Green paper on an EU approach to managing economic migration (COM(2004) 811 final) which led to the adoption of a policy plan on legal migration (COM(2005) 669 final) at the end of 2005. In July 2006, the European Commission adopted a Communication on policy priorities in the fight against illegal immigration of third-country nationals (COM(2006) 402 final), which aims to strike a balance between security and an individuals’ basic rights during all stages of the illegal immigration process. In September 2007, the European Commission presented its third annual report on migration and integration (COM(2007) 512 final). A European Commission Communication adopted in October 2008 emphasised the importance of strengthening the global approach to migration: increasing coordination, coherence and synergies (COM(2008) 611 final) as an aspect of external and development policy. The Stockholm programme, adopted by EU heads of state and government in December 2009, sets a framework and series of principles for the ongoing development of European policies on justice and home affairs for the period 2010 to 2014; migration-related issues are a central part of this programme. In order to bring about the changes agreed upon, the European Commission enacted an action plan implementing the Stockholm programme – delivering an area of freedom, security and justice for Europe’s citizens (COM(2010) 171 final) in 2010.

In May 2013, the European Commission published the 'EU Citizenship Report 2013'. The Report notes that 'EU citizenship brings citizens new rights and opportunities. Moving and living freely within the EU is the right they associate most closely with EU citizenship. Given modern technology and the fact that it is now easier to travel, freedom of movement allows Europeans to expand their horizons beyond national borders, to leave their country for shorter or longer periods, to come and go between EU countries to work, study and train, to travel for business or for leisure, or to shop across borders. Free movement increases social and cultural interactions within the EU and creates closer bonds between Europeans. In addition, it generates mutual economic benefits for businesses and citizens, including those who remain at home, as the EU steadily removes internal obstacles.
