Household types

  • 2.86 million households with on average 2.3 persons

    At the beginning of 2021, there were 2.86 million private households in the Flemish Region. On average, a private household consisted of 2.31 persons.

    Since 2000, the number of private households has increased faster than the number of inhabitants. Hence the average size of a private household has decreased. In 2000, a private household consisted of 2.45 persons on average.

  • Single-person households most common household type

    At the beginning of 2021, the 3 most common private household types were: single-person households (32%), married couples without children living at home (22%) and married couples with 1 or more children living at home (21%).

    Between 2000 and 2020, the percentage of households with married couples with 1 or more children living at home dropped from 34% to 21%. The percentage of households with unmarried couples with 1 or more children living at home increased in this period to 8%. The percentage of single-person households also increased, and since 2006 this has been the most common household type. The percentage of single-parent households hardly changed in recent years.

  • Slightly more unmarried couples with child(ren) than without children among younger households

    In the beginning of 2021, the younger households (with a reference person younger than 65 years) were largely composed of married couples with 1 or more children living at home (30%) and single-person households (27%).

    Married couples made up 4 out of 10 younger households; unmarried couples accounted for 2 out of 10 younger households.

    Among married and unmarried couples there were slightly more couples with children than without children living at home. More than 1 out of 10 households was a single-parent household.

    Among the older households (with a reference person of 60 years or older), married couples without children living at home (42%) and single-person households (40%) were most common in 2021.

    Half of the older households were married couples. 3% were unmarried couples and 4% were single-parent households.

  • Married couples and married parents remain most common household types

    In the beginning of 2021, in nearly 6 out of 10 private households partners were living together.

    Within the households with partners living together, 3 out of 4 couples were married. There were somewhat more married couples without children living at home than with children living at home. Among the unmarried couples, a small majority had children living at home.

    In almost 4 out of 10 private households there were children living at home. The parents (or parent and partner of the parent) were married in nearly 6 out of 10 families. Single-parent households were slightly more common than unmarried couples with child(ren).

  • More than 4 out of 10 families with 1 child living at home

    In the beginning of 2021, there were more than 4 out of 10 families with 1 child. This means that the family already had 1 child living at home or that only 1 child still lived with its parent(s). A family in 2021 had on average 1.79 children.

    6 out of 10 single-parent families had 1 child living at home. On average, 1.55 children lived with a single mother or father. Married and unmarried couples had just as often 2 children . Unmarried couples were slightly more likely to have 1 child, while married couples were slightly more likely to have more than 2 children. On average, married couples had 1.91 children and unmarried couples had 1.74 children.

  • More one-person households in coastal municipalities and university cities

    At the beginning of 2021, almost 1 in 3 private households in the Flemish Region was a single-person household.

    The percentage of private households with persons living alone varied per municipality between 21% and 47%. The highest percentages were found in the coastal municipalities and in the university cities. This variation is partly related to the age of the inhabitants.

  • More married couples in the Flemish Region than in other regions

    At the start of 2021, there were relatively more married couples without resident children in the Flemish Region than in the other regions. The Flemish Region also had the highest percentage of married couples with children living at home. Relatively speaking, the Flemish Region counted fewer single-person households than the other regions. The percentage of single-parent households was also lowest there.

    The Brussels-Capital Region had the highest percentage of single-person households.

    The Walloon Region showed a somewhat higher percentage of unmarried couples with children living at home.

  • Large European variation in single-person households

    In 2019, the percentage of single-person households in the Flemish Region was slightly below the EU average. The percentage in the Walloon Region was slightly above this average. The percentage in the Brussels-Capital Region, along with those in the Scandinavian countries and in Germany, belonged to the group with the highest percentages of single-person households.
