3. Families with children constitute 39 per cent of the population
At the end of 2016, there were 569,700 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 1,794 from the previous year. The drop was around 300 lower than in the year before. The number of families with children under the age of seven decreased by 3,000 families from the year before.

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.
3.1 One-fifth 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-nine 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 numbers of all other types of families with children grew over the year. At the end of 2016, there were 111,300 families of cohabiting couples with underage children in Finland, which equals 20 per cent of all families with underage children. Compared with 2015, the number of families of cohabiting couples increased by 416.
Nowadays 58 per cent of firstborn children are born outside marriage. The share has slowly increased, by eight percentage points since 1997, when one-half of firstborn children were born outside marriage. Forty-five per cent of all children born in 2016 were born outside marriage.
The number of families formed by a mother and children has grown by 1,700 compared with 2015. At the end of 2016, families formed by a mother and children numbered around 106,000. 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 a father and children are still quite rare. There are only 17,200 such families. Families composed of a registered couple and children under the age of 18 are even rarer, numbering around 651. The relative growth in the number of these families was eight per cent compared with the previous year.

3.2 Of parents of reconstituted families, 48 per cent were married
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.
There are 51,600 reconstituted families representing nine per cent of all families with underage children. The number of reconstituted families has grown slowly since 1990 when the first statistics concerning them were made, but in the past ten years, their number has more or less stayed on the same level, and even fallen slightly in some years. From 2015, the number of reconstituted families diminished by 615.
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 928.

3.3 Number of families with two children has grown slightly
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 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 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. In contrast, the decrease in the number of families with two children has halted, their number has even grown slightly. The number of families with at least four children remained at the same level in 2016 as in the year before. At the end of 2016, there were 449 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 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.
