3. Thirty-nine per cent of families are families with children

At the end of 2017, there were 566,242 families with underage children in Finland. A family with underage children has at least one child under the age of 18 living at home. Families with underage children make up 39 per cent of all families. The percentage has been falling at a steady rate for the past few years. In all, 39 per cent of the population live in families with underage children, older siblings included.

The number of families with underage children fell by 3,434 from the previous year. The drop is 1,640 larger than in the year before. The number of families with children under the age of seven has decreased by 5,028 families from the year before.

1) The breakdown of the census by type of family has been revised on the basis of interview surveys. (Aromaa, Cantell & Jaakkola: Avoliitto (Consensual Union), Research Institute of Legal Policy 49, Helsinki 1981).
2) The breakdown of the census by type of family has been revised on the basis of the 1981 register-based material on families and cohabiting couples.
3) Families of the type “same-sex married couple with children” numbered 388.

3.1 Fifty-eight per cent of families with underage children are families of cohabiting couples

The most common family with children is still that consisting of a married couple and children. Fifty-eight per cent of the families with children were families of married couples. This is the form of family with children which has seen a steady decline, both in absolute and relative terms, but other family forms with children are still far from its numbers. The number of families with a cohabiting couple and children also diminished. In contrast, the numbers of other types of families with children grew over the year. At the end of 2017, there were almost 111,100 families of cohabiting couples with underage children in Finland, which equals to 20 per cent of all families with underage children. Compared with 2016, the number of families of cohabiting couples decreased by 242.

Nowadays 57 per cent of firstborn children are born outside the marriage. Forty-five per cent of all children born in 2017 were born outside the marriage.

The number of families formed by a mother and children has grown by 1,200 families compared with 2016. At the end of 2017, families formed by mothers and children numbered 106,939. Over one-fifth (22%) of all families with children are one-parent families (mother and children or father and children). Families with children whose regular composition is father and children are still quite rare. There are only 17,641 such families.

At the beginning of March 2017, an amendment to the Marriage Act entered into force, as a result of which part of registered partners changed their partnership into marriage and new registered partners can no longer be formed. The number of families formed by a registered couple and children aged under 18 has declined by around 300 from the previous year. Now there are only 345 families formed by a registered couple and children. At the end of 2017, there were 388 families of same-sex married couples with children.

3.2 Number of reconstituted families fell, but the share remained unchanged

A reconstituted family refers to a family that has a non-common child under the age of 18, i.e. the child has, in a sense, received a new social parent. The concept is more broadly interpreted in everyday talk: the weekend families born in consequence of diverse family splits are referred to as reconstituted families. However, statistics on families must be compiled according to the child’s permanent place of residence. A child cannot be included in two families in the statistics. Divorced fathers and mothers with whom children only stay during weekends and holidays are not included in family statistics unless they have formed a new family. Families of same-sex couples are not taken into consideration in the examination of reconstituted families.

There are 51,300 reconstituted families representing nine per cent of all families with underage children. The number of reconstituted families grew slowly since 1990 when the first statistics concerning them were made. In the past ten years, their number has more or less stayed on the same level, but it seems to have turned to a decline in the last few years. From 2016, the number of reconstituted families diminished by 321.

Usually, the child of a reconstituted family is the mother’s and has obtained a new social father. Altogether, 48 per cent of the parents of reconstituted families are married to one another and 52 per cent cohabit. If a common child is born to a reconstituted family, the parents usually marry, but otherwise they mostly cohabit. Families with “your children, my children and our children” living in the same household are still relatively rare, numbering 944.

3.3 Number of families with two children has again decreased

When examining the number of children in families, allowance must be made for the family’s stage of life. For example, families which have only had their firstborn are processed as one-child families in the statistics, as are also families with only their last-born living at home. Family statistics thus represent a cross-section of the situation at a given moment, i.e. the sizes of families in the country at a given point in time, and not the eventual numbers of children in families. Hence, it is difficult to compare the statistics relating to different points in time because of the uneven age structure of the population.

The clearest long-term change in the number of children in families is the fall in the number and relative proportion of families with at least four children since the 1960s (Table 7). After the mid-1980s, the number of families with at least four children started to grow, although over the 2000s, the growth has been slow. The number of families with one child has been falling steadily. After two exceptional years, the number of families with two children has also continued falling. From 2016, the number of these families diminished by 685. In 2017, the number of families with three children remained at the same level and that of families with at least four children almost on level with the previous year. At the end of 2017, there were 438 families with at least ten underage children.

The average number of children in a family with underage children is not directly comparable at different points in time, because the sizes of the age groups at various stages of family life vary. This does not give exactly unambiguous information either, since the childbearing age has continuously risen. In the 2000s, the average number of children in a family with children has remained nearly unchanged.

The recent trend can be seen in Figure 6, which shows the average number of underage children living at home according to the mother's age. The fact that women giving birth have become older is visible in that mothers aged over 40 have approximately the same number of children in each age group as in the previous year and clearly more than in 1995. In turn, mothers aged under 35 have the same number or slightly fewer children than in the mid-1990s.
