5. Sixty-three per cent of children live in a family of married couples

Families with children can also be examined by taking the child as the statistical unit instead of the family. Then the results are slightly different. For example, 58 per cent of the families with underage children are those of married couples, but 63 per cent of all children live in families of married couples, because these families have a higher average number of children than families of cohabiting couples or one-parent families. When the children of cohabiting couples and those of registered couples are included in the calculation, 81 per cent of underage children live in families with two parents.

5.1 Twenty-three per cent of children have no siblings

Although 43 per cent of families with children had only one child at the end of 2017, only 23 per cent of the children in these families had no siblings. The status of an only child is temporary for many of these children, as the majority of them will have a sibling later on. Some of these children may also have had an older sibling who has already turned 18 or moved away from home.

At the end of 2017, altogether 42 per cent of all children lived with one sibling and 35 per cent of all children had at least two siblings living at home. In 1985, only 27 per cent of all children had at least two siblings at home.

The cross-sectional nature of family statistics is clearly illustrated in Figure 9, which shows the children of families by age and number of children in the family. Here all children living at home and aged under 18 are taken into account when determining the status of an only child. Of children aged under one year, 41 per cent are without siblings, i.e. they are firstborns in their families. The proportion of children without siblings, 13 per cent, is the lowest for children aged 7 to 8.

A second child has most likely been born to a family when the firstborn is aged around nine. On the other hand, the older sibling has only on rare occasions reached the age of 18. Since it can be assumed that some of the children aged 7 to 8 will still have a sibling and some of them already have one who has left home, it can be concluded that some ten per cent of children will remain permanently without siblings. The same results are attained when looking at the number of children according to the number of children born to women in the whole country.

Figure 9 indicates that a child’s family is at its largest when he/she is nine years old. Around 43 per cent of children of that age live in families with at least three underage children.

5.2 Number of siblings varies much between areas

There are also differences in the numbers of siblings by area. In areas where families are bigger, the proportion of children living with several siblings is naturally larger than in areas of small families. In North Ostrobothnia, 29 per cent of children have three or more siblings aged under 18 living at home. In contrast, nearly every tenth child in South Karelia, Uusimaa and Varsinais-Suomi is living with at least three siblings. In Åland, only seven per cent of children live with this many siblings.

North, Central and South Ostrobothnia also have the lowest proportions of children living without siblings − under 20 per cent. More than every fourth child in Åland, South Karelia and Uusimaa has no siblings living at home.

5.3 Seven per cent of children have obtained a new social parent

In all, 107,769 children (10 per cent of all children) aged under 18 are raised in reconstituted families. The number of children raised in reconstituted families declined slightly from the previous year and the relative share remained nearly unchanged. Of them, 32,855 are the spouses' common children, that is, born to a family that previously had the mother’s and/or the father’s children only. Altogether, 44 per cent of reconstituted families have had common children born to the family as well. There are 74,914 actual children of reconstituted families (7% of all children), that is, children who have obtained a new social parent. Of these children, 63,798 were brought into the family by their mother and 11,116 by their father.

5.4 No change in the proportion of children with foreign background in the second generation

During 2012, Statistics Finland adopted a new origin classification. Persons whose at least one parent who was born in Finland are considered to be of Finnish background. Also, persons whose parents' data are unknown but whose native language is Finnish, Swedish or Sami are considered to be of Finnish background. Persons whose both parents or the only known parent were born abroad are considered to be of foreign background. Persons who were born abroad and whose both parents' data are unknown are also considered to be of foreign background. Using the origin classification, it is easy to distinguish between first (born abroad) and second (born in Finland) generation Finns with a foreign background. The following looks at all children belonging to the population of Finland.

Based on what is stated above, 86,000 or eight per cent of all underage children were of foreign background at the end of 2017. During the year, the number of underage children with foreign background has grown by over five thousand. In 1990, there were 3,500 underage children with foreign background in Finland.

Until 2003, there were more children with foreign background in the first generation than in the second generation, but in the following year there were slightly more children with foreign background in the second generation, 51 per cent. At the end of 2017, the share of children with foreign background in the second generation among all children with foreign background was 61 per cent. In recent years, the ratio has remained unchanged.
