There is some debate among experts as to what the important component of the family structure is, particularly in the US, centering on whether or not a complete family or the love and affection of the children's parents is more important.
Along with this, the areas where there are an extremely high number of children living in single parent homes include Africa, Europe, Latin America, North America, and Oceania.
It has also been shown that children living in areas of South Africa are the very most likely to live with a single parent.
This is highlighted in a report published by Gingerbread, funded by Trust for London and Barrow Cadbury Trust.
A single parent is a parent that parents alone without the other parent's support, meaning this particular parent is the only parent to the child, responsible for all financial, material, and emotional needs.
It means there is an absence of the other parent as opposed to a co-parent, meaning that the parent is not the only parent regardless of whether or not they are a couple. There is no true definition of what "single parent" means and is more based on opinions.
The 1980 United States Census reported that 19.5% were single parent households.
From 1980 to 2009, the percentage of single-parent households jumped to 29.5%.
