Single parent

Among all households in OECD countries in 2011, the proportion of single-parent households was in 3-11% the range, with an average of 7.5%. It was highest in Australia (10%), Canada (10%), Mexico (10%), United States (10%), Lithuania (10%), Costa Rica (11%), Latvia (11%) and New Zealand (11%), while it was lowest in Japan (3%), Greece (4%), Switzerland (4%), Bulgaria (5), Croatia (5%), Germany (5%), Italy (5%) and Cyprus (5%). The proportion was 9% in both Ireland and the United Kingdom.[8]

Among households with children in 2005/09, the proportion of single-parent households was 10% in Japan, 16% in the Netherlands, 19% in Sweden, 20% in France, 22% in Denmark, 22% in Germany, 23% in Ireland, 25% in Canada, 25% in the United Kingdom, and 30% in the United States. The U.S. proportion increased from 20% in 1980 to 30% in 2008.[9]

In all OECD countries, most single-parent households were headed by a mother. The proportion headed by a father varied between 9% and 25%. It was lowest in Estonia (9%), Costa Rica (10%), Cyprus (10%), Japan (10%), Ireland (10%) and the United Kingdom (12%), while it was highest in Norway (22%), Spain (23%), Sweden (24%), Romania (25%) and the United States (25%). These numbers were not provided for Canada, Australia or New Zealand.[8]

In 2016/17, the proportion of children living in a single-parent household varied between 6% and 28% in the different OECD countries, with an OECD country average of 17%. It was lowest in Turkey (2015, 6%), Greece (8%), Croatia (8%) and Poland (10%), while it was highest in France (23%), United Kingdom (23%), Belgium (25%), Lithuania (25%), United States (27%) and Latvia (28%). It was 19% in Ireland and Canada.[10]

Among children living in a single-parent household, most live primarily with their mother, others primarily with their father, while other children have a shared parenting arrangement where they spend an approximately equal amount of time with their two parents. Among those living primarily with one single parent, most live with their mother. In 2016 (or latest year available), the proportion of 6-12 year olds living primarily with their single father ranged between 5% and 36% among the different OECD countries. It was highest in Belgium (17%), Iceland (19%), Slovenia (20%), France (22%), Norway (23%) and Sweden (36%), while it was lowest in Lithuania (4%), Ireland (5%), Poland (5%), Estonia (7%), Austria (7%) and the United Kingdom (8%). It was 15% in the United States.[11]

In 2005/06, the proportion of 11- to 15-year-old children living in a shared parenting arrangement versus with only one of their parents varied between 1% and 17%, being the highest in Sweden. It was 5% in Ireland and the United States, and 7% in Canada and the United Kingdom.[12] By 2016/17, the percentage in Sweden had increased to 28%.[13]

Over 9.5 million American families are run by one woman. Single mothers are likely to have mental health issues, financial hardships, live in a low income area, and receive low levels of social support. All of these factors are taken into consideration when evaluating the mental health of single mothers. The occurrence of moderate to severe mental disability was more pronounced among single mothers at 28.7% compared to partnered mothers at 15.7%.[14] These mental disabilities include but are not limited to anxiety and depression. Financial hardships also affect the mental health of single mothers. Women, ages 15–24, were more likely to live in a low socio-economic area, have one child, and not to have completed their senior year of high school. These women reported to be in the two lowest income areas, and their mental health was much poorer than those in higher income areas.[14]

A similar study on the mental health of single mothers attempted to answer the question, "Are there differences in the prevalence of psychiatric disorders, between married, never-married, and separated/divorced mothers?" Statistically, never married, and separated/divorced mothers had the highest regularities of drug abuse, personality disorder and PTSD.[15] The family structure can become a trigger for mental health issues in single mothers. They are especially at risk for having higher levels of depressive symptoms.[16]

Studies from the 1970s showed that single mothers who are not financially stable are more likely to experience depression.[17] In a more current study it was proven that financial strain was directly correlated with sky rocket levels of depression.[17] Among low-income, single mothers, depressive symptoms may be as high as 60%.[18]

Inadequate access to mental health care services is prevalent amongst impoverished women. Low-income women are less likely to receive mental health care for numerous reasons. Mental health services remain inequitable for low-income, more so, low-income single women are more likely to suffer from depression, anxiety, and other poor mental health outcomes. Researchers Copeland and Snyder (2011) addressed the barriers low-income single mothers have on receiving mental health care, "Visible barriers often include the lack of community resources, transportation, child care, convenient hours, and financial resources." Meanwhile, low-income single mothers are more likely to bring their children in for mental health treatment than themselves. Researchers Copeland and Snyder analyzed sixty-four African American mothers who brought their children in for mental health treatment. These mothers were then screened for mild, moderate, and severe depression and/or anxiety. After three months the researchers used an ethnographic interview to address whether or not the participants used mental health services that were referred to them. Results indicated that the majority of the participants did not use the referred mental health care services for reasons that included: fear of losing their children, being hospitalized and/or stigmatized by their community counterparts.[19]

Historically, death of a partner was a common cause of single parenting. Diseases and maternal death not infrequently resulted in a widower or widow responsible for children. At certain times wars might also deprive significant numbers of families of a parent. Improvements in sanitation and maternal care have decreased mortality for those of reproductive age, making death a less common cause of single parenting.

In 2009, the overall divorce rate was around 9/1000 in the United States. It was also found that more influence came from the south, with the rates there being about 10.5/1000, as opposed to the north where it was around 7/1000.[37] This resulted in about 1.5% (around 1 million) children living in the house of a recently divorced parent in the same year.[38] Along with this, it has been shown that for the past 10 years or so, first marriages have a 40% chance of ending in divorce. And, for other marriages after a first divorce, the chance of another divorce increases. In 2003, a study showed that about 69% of children in American living in a household that was a different structure than the typical nuclear family. This was broken down into about 30% living with a stepparent, 23% living with a biological mother, 6% with grandparents as caregivers, 4% with a biological father, 4% with someone who was not a direct relative, and a small 1% living with a foster family.[39]

Around the mid-1990s, there was a significant amount of single parents raising children, with 1.3 million single fathers and 7.6 million single mothers in the United States alone. However, many parents desire, or attempt, to get sole custody, which would make them a single parent, but are unsuccessful in the court process. There are many parents who may single parent, but do so without official custody, further biasing statistics.

Child custody in reference to divorce refers to which parent is allowed to make important decisions about the children involved. Physical custody refers to which parent the child lives with. Among divorced parents, "parallel parenting" refers to parenting after divorce in which each parent does so independently; this is most common. In comparison, cooperative parenting occurs when the parents involved in the child's life work together around all involved parties' schedules and activities, and this is far less common. After a certain "crisis period," most children resume normal development; however, their future relationships are often affected, as they lack a model upon which to base a healthy long-term relationship. Nonetheless, as adults children of divorcees cope better with change.[40][41][42]

Children are affected by divorce in many different ways, varying by the circumstances and age of the child. Young children ages two to six are generally the most fearful of parental separation, and often feel abandoned or confused. Both boys and girls have the same amount of trouble coping, but often show this in different ways. Nonetheless this age group adapts best to their situations, as they are often too young to remember their non-custodial parent vividly. Children ages seven to twelve are much better at expressing emotions and accepting parentage breakage, but often distrust their parents, rely on outside help and support for encouragement, and may manifest social and academic problems. Adolescents cope the worst with divorce; they often struggle most with the change, and may even turn away from their family entirely, dealing with their situation on their own. They often have problems expressing feelings, similar to far younger children, and may have adjustment issues with long-term relationships due to these feelings.[43] Keeping in touch with both parents and having a healthy relationship with both mother and father appears to have the most effect on a child's behavior; which leads to an easier time coping with the divorce as well as development through the child's life.[44] Children will do better with their parents divorce if they have a smooth adjustment period. One way to make this adjustment easier on children is to let them "remain in the same neighborhoods and schools following divorce."[45]

Some out-of-wedlock births are intended, but many are unintentional. Out-of-wedlock births are frequently not acceptable to society, and they often result in single parenting. A partner may also leave as he or she may want to shirk responsibility of bringing up the child. This also may harm the child.[46] Where they are not acceptable, they sometimes result in forced marriage, however such marriages fail more often than others.

In the United States, the rate of unintended pregnancy is higher among unmarried couples than among married ones. In 1990, 73% of births to unmarried women were unintended at the time of conception, compared to about 44% of births overall.[47]

Mothers with unintended pregnancies, and their children, are subject to numerous adverse health effects, including increased risk of violence and death, and the children are less likely to succeed in school and are more likely to live in poverty and be involved in crime.

"Fragile Families" are usually caused by an unintended pregnancy out of wedlock. Usually in this situation the father is not completely in the picture and the relationship between the mother, father, and child is consistently unstable. As well as instability "fragile families" are often limited in resources such as human capital and financial resources, the kids that come from these families are more likely to be hindered within school and don't succeed as well as kids who have strictly single parents or two parent homes.[48] Usually within these families the father plans to stick around and help raise the child but once the child is born the fathers do not stay for much longer and only one third stay after five years of the child's birth.[49] Most of these fragile families come from low economic status to begin with and the cycle appears to continue; once the child grows up they are just as likely to still be poor and live in poverty as well.[50] Most fragile families end with the mother becoming a single parent, leaving it even more difficult to come out of the poverty cycle. The gender of the baby seems to have no effect if the father is not living with the mother at the time of the birth, meaning they are still likely to leave after one year of the child's birth. Yet there is some evidence that suggests that if the father is living with the mother at the time of the birth he is more likely to stay after one year if the child is a son rather than a daughter.[51]

Some individuals choose to become pregnant and parent on their own. Others choose to adopt. Typically referred to in the West as "Single Mothers by Choice" or "Choice Moms" though, fathers also (less commonly) may choose to become single parents through adoption or surrogacy. Many turn to single parenthood by choice after not finding the right person to raise children with, and for women, it often comes out of a desire to have biological children before it is too late to do so.

Single parent adoptions have existed since the mid 19th century. Men were rarely considered as adoptive parents, and were considered far less desired. Often, children adopted by a single person were raised in pairs rather than alone, and many adoptions by lesbians and gay men were arranged as single parent adoptions. During the mid 19th century many state welfare officials made it difficult if not impossible for single persons to adopt, as agencies searched for "normal" families with married men and women. In 1965, the Los Angeles Bureau of Adoptions sought single African-Americans for African-American orphans for whom married families could not be found. In 1968, the Child Welfare League of America stated that married couples were preferred, but there were "exceptional circumstances" where single parent adoptions were permissible.[52]

Not much has changed with the adoption process since the 1960s. However, today, many countries only allow women to adopt as a single parent, and many others only allow men to adopt boys.[53]

Single parent adoptions are controversial. They are, however, still preferred over divorcees, as divorced parents are considered an unnecessary stress on the child.[54] In one study, the interviewers asked children questions about their new lifestyle in a single-parent home. The interviewer found that when asked about fears, a high proportion of children feared illness or injury to the parent. When asked about happiness, half of the children talked about outings with their single adoptive parent.[55] A single person wanting to adopt a child has to be mindful of the challenges they may face, and there are certain agencies that will not work with single adoptive parents at all. Single parents will typically only have their own income to live off of, and thus might not have a backup plan for potential children in case something happens to them.[56] Traveling is also made more complex, as the child must either be left in someone else's care, or taken along.[57]

In 2003, 14% of all Australian households were single-parent families.[58] In Australia 2011, out of all families 15.9% were single parent families. Out of these families 17.6% of the single parents were males, whilst 82.4% were females.[59]

Single people are eligible to apply for adoption in all states of Australia, except for Queensland and South Australia. They are able to apply for adoption both to Australian born and international born children, although not many other countries allow single parent adoptions.[60]

Single parents in Australia are eligible for support payments from the government, but only if they are caring for at least one child under the age of eight.[61]

At the 2013 census, 17.8% of New Zealand families were single-parent, of which five-sixths were headed by a female. Single-parent families in New Zealand have fewer children than two-parent families; 56% of single-parent families have only one child and 29% have two children, compared to 38% and 40% respectively for two-parent families.[62]

In the United Kingdom, about 1 out of 4 families with dependent children are single-parent families, 8 to 11 percent of which have a male single-parent.[63][64][65] UK poverty figures show that 52% of single parent families are below the Government-defined poverty line (after housing costs).[66] Single parents in the UK are almost twice as likely to be in low-paid jobs as other workers (39% of working single parents compared with 21% of working people nationally). This is highlighted in a report published by Gingerbread, funded by Trust for London and Barrow Cadbury Trust.[67]

In the United States, since the 1960s, there has been a marked increase in the number of children living with a single parent. The jump was caused by an increase in births to unmarried women and by the increasing prevalence of divorces among couples. In 2010, 40.7% of births in the US were to unmarried women.[68] In 2000, 11% of children were living with parents who had never been married, 15.6% of children lived with a divorced parent, and 1.2% lived with a parent who was widowed.[69][70] The results of the 2010 United States Census showed that 27% of children live with one parent, consistent with the emerging trend noted in 2000.[71] The most recent data of December 2011 shows approximately 13.7 million single parents in the U.S.[72] Mississippi leads the nation with the highest percent of births to unmarried mothers with 54% in 2014, followed by Louisiana, New Mexico, Florida and South Carolina [73]

In 2006, 12.9 million families in the US were headed by a single parent, 80% of which were headed by a female.[74][75]

The newest census bureau reports that between 1960 and 2016, the percentage of children living in families with two parents decreased from 88 to 69. Of those 50.7 million children living in families with two parents, 47.7 million live with two married parents and 3.0 million live with two unmarried parents.[76]

The percentage of children living with single parents increased substantially in the United States during the second half of the 20th century. According to a 2013 Child Trends study, only 9% of children lived with single parents in the 1960s—a figure that increased to 28% in 2012.[77] The main cause of single parent families are high rates of divorce and non-marital childbearing.
