Household composition statistics

Data extracted in August 2017. Most recent data: Further Eurostat information, Main tables and Database. Planned article update: September 2018.

This article presents data on household size and household types in the European Union (EU). The Labour Force Survey (LFS), a large household survey in the EU-28, is used to provide the estimates.

Main statistical findings

Household size

In 2016, the average household size in the EU-28 was 2.3 members (Figure 1). The largest average household size was recorded in Croatia (2.8 members), while the smallest were observed in Sweden (1.9 members), Germany and Denmark (both 2.0 members). The biggest decrease since 2006 was observed in Lithuania, with an average household size going from 2.8 members in 2006 to 2.1 members in 2016. Croatia is the only EU Member State where the average household size increased from 2006 to 2016 (from 2.7 to 2.8 members).

Looking at the number of persons by household, almost two thirds of all households in the EU-28 were composed of one or two persons in 2016. The most common type of household was that composed of a single person (Figure 2), with one third (33.1 %) of the total number of households. This group also recorded the highest increase from 2006 to 2016 (3.4 percentage points). Households composed of two persons corresponded to 31.7 % of the total number of households in 2016 (0.8 pp increase since 2006). Larger households were less common and their share decreased with the increase in number of persons: 15.9 % were composed of three persons, 13.4 % by four persons, while households with five persons or more accounted for 5.8 % of the total number of households in 2016. Over the last decade, the relative importance of the larger households fell, with the biggest reduction recorded among those households composed of four persons (a fall of 1.6 pp.).

With the average size of private households decreasing and the total population of the EU-28 continuing to grow (albeit at a relatively slow pace), there was an increase in the overall number of households. The total number of private households within the EU-28 rose from 199 million in 2006 to 220 million in 2016 (Table 1). This corresponds to an average growth of 1.05 % per year. Luxembourg and Cyprus were the only EU Member States with an expansion in the number of households of at least 2 % per year, followed by Slovenia with an increase of 1.8 % per year. The only EU Member States with a decrease in the number of households from 2006 to 2016 were Croatia (0.57 % per year) and Bulgaria (0.44 % per year).

Household types

In 2016 in the EU-28, 29.8 % of the population living in private households lived in households which had children (Figure 3). Across the EU Member States, the highest percentages were observed in Ireland (40.7 %), Cyprus (38.4 %) and Poland (38 %), the lowest in Germany (22.1 %) and Finland (22.2 %). The share of the population living in private households with children was particularly high in Turkey (52.5 %) and the former Yugoslav Republic of Macedonia (50.1 %), by far exceeding the average of the EU Member States.

The most common household type in the EU-28 in 2016 was a single person living alone (33.1 %). Among households with more than one adult, the most common household type consisted of 'couple without children', accounting for 24.9 % of all private households (Table 1 and Figure 3). The next most common household type was composed of 'couple with children', of which there were 44.1 million in 2016 (20.1 % of all private households).

Looking at developments since 2006, the share of EU-28 households with children decreased by more than 2 percentage points (from 32.2 % in 2006 to 29.8 % in 2016), couples with children becoming relatively less frequent (from 21.3 % in 2006 to 20.1 % in 2016). The share of single adults with children, however, increased (from 4.0 % in 2006 to 4.4 % in 2016). Over the same period, the proportion of couples without children and the proportion of single adults without children rose from 23.9 % to 24.9 % and from 29.3 % to 33.1 % respectively.

Figure 3 extends the analysis of household composition: Ireland recorded the highest share of couples with children (27.9 %), followed by Cyprus (25.7 %) and Luxembourg (24.1 %). Ireland, moreover, registered a high proportion of single-parent households (6.0 %), making it the only EU Member State to have more than 40 % of its households with children (40.7 %). Only six EU Member States, namely Denmark (8.8 %), Lithuania (7.8 %), the United Kingdom (6.7 %), Sweden (6.4 %), Estonia (6.2 %) and France (6.2 %), recorded a higher proportion of households composed of single adults with children.

By contrast, the share of households with children was at its lowest level in Finland and Germany (both with 22.1 %). Lithuania was the EU Member State with the smallest proportion of couples with children (14.2 %). The lowest share of single adults with children was, however, recorded in Croatia (1.8 %), the only EU Member State where households composed of single adults with children accounted for less than 2 % of the total number of households.

Data sources and availability

The European Union (EU) Labour Force Survey (LFS) measures the labour status and other characteristics of the population in an average week in each quarter. It covers all citizens living in private households and excludes those in collective households.

Under the specific topic 'Households statistics', the EU-LFS currently covers statistics on household composition and number and size of households. Only annual data are available.


A child is defined as a household member aged less than 25 years and in full social and economic dependence from other household member/-s (parents/ adults).


In addition to the Labour Force Survey (LFS), the EU-Statistics on Income and Living Conditions (EU-SILC) is also a source of household statistics. The EU-SILC is a multi-purpose instrument which focuses mainly on income. However, information on housing conditions, social exclusion, labour and education is also collected.
