Co-Parenting & Custody Statistics 2026: Shared Custody, Child Support & Outcomes

How common is 50/50 custody? Who actually gets the kids, and does shared parenting help children? This page collects the custody and co-parenting numbers that answer those questions — every figure verified against and linked to its primary source (US Census Bureau, Eurostat, national statistics offices, peer-reviewed journals), plus original data from SplitDay's own 2026 custody-setup study. Last updated July 7, 2026.

Key custody statistics for 2026

• 78.2% of US custodial parents are mothers; 21.8% are fathers (US Census Bureau, 2022).
• Shared physical custody after US divorce more than doubled — from 13% before 1985 to 34% in 2010–2014 (Demographic Research, 2022).
• 22.2 million US children — 27.1% of all children under 21 in families — have a parent living outside their household (US Census Bureau, 2022).
• Spain now awards custodia compartida in 49.7% of divorces involving children — more than sole maternal custody (INE, 2024).
• Sweden leads the world: roughly 45% of children whose parents live apart alternate between both homes (Statistics Sweden, 2022/23).
• Children in joint physical custody did better than sole-custody peers in 34 of 60 studies — and worse in only 6 (Journal of Child Custody review, 2018).
• Only 37.3% of US custodial parents have a legal child support agreement, down from 55.1% in 2003 (US Census Bureau, 2022).
• 42% of separating parents choose a 50/50 split when they first set up a custody calendar (SplitDay data study, 2026, n=804).

How common is shared custody in the US?

The likelihood of shared physical custody after a US divorce more than doubled from 13% before 1985 to 34% in 2010–2014, according to a 2022 study in Demographic Research using Census child-support data.

Court records tell the same story. In Wisconsin — one of the few states with decades of consistent records — mother-sole custody fell from 80% of divorce cases in 1986 to 42% in 2008, while equal shared custody rose from 5% to 27% (Cancian et al., Demography, 2014).

Averaged across all 50 states, a father is still likely to receive about 35% of child custody time, per Custody X Change's 50-state study.

Custodial mothers and fathers

The US had 13.9 million custodial parents in 2022: 78.2% mothers, 21.8% fathers. In the same year, 22.2 million children — 27.1% of all US children under 21 living in families — had one parent living outside their household (US Census Bureau, P60-285).

Internationally, 23% of US children under 18 live with a single parent and no other adults — more than three times the worldwide share of 7% and the highest rate among 130 countries studied (Pew Research Center, 2019).

Child support: what's owed vs. what arrives

• US custodial parents with support agreements were due an average of $6,390 per year (about $533/month) in 2022; the median was $4,816.
• Of the $29.9 billion in child support owed in 2022, only $19.2 billion was actually received.
• Just 37.3% of custodial parents had a legal child support agreement in 2022 — down from 55.1% in 2003 — and about three in four parents owed support received at least one payment.

Divorce and children

• The US recorded 672,502 divorces in 2023 — 2.4 per 1,000 population (CDC/NCHS).
• The EU recorded an estimated 0.7 million divorces in 2024 — 1.6 per 1,000 persons, against 3.9 marriages (Eurostat).
• In Germany, about 129,300 couples divorced in 2024 and roughly 111,000 minor children were affected; 50.8% of divorcing couples had children under 18 (Destatis).

Does shared custody help children?

A 2018 review of 60 studies in the Journal of Child Custody found children in joint physical custody had better outcomes than sole-custody children on all measures in 34 studies, and equal-to-better outcomes in another 14 — independent of family income and parental conflict. In only 6 studies did they do worse on any single measure.

The largest single study is Swedish: among 147,839 twelve- and fifteen-year-olds, children in joint physical custody reported fewer psychosomatic problems than children living mostly or only with one parent (Bergström et al., Journal of Epidemiology & Community Health, 2015).

Parents themselves agree: more than 90% of German separated parents who share care report good or very good experiences with their arrangement (Bundestag research service, 2025).

Custody around the world

Across Europe, the share of children of separated parents in symmetric alternating residence roughly doubled from about 6% to about 12% in under 20 years, per EU-SILC-based research summarized by the German Bundestag research service. Country by country:

Note the measures differ — some countries count court awards in a single year, others count all children currently in an arrangement — so treat cross-country gaps as directional. A survey-based EU-SILC estimate puts Sweden even higher, at 53%.

For France historically: among couples who divorced in 2009, one year later 76% of children lived mainly with their mother, 9% with their father and 15% alternated (Insee Première n°1536).

Most custody cases never reach trial

In a 2021 survey of 1,000 US adults who finalized a divorce involving custody, 79% reached a custody settlement rather than going to trial, and 93% tried at least one alternative dispute-resolution method — over half used mediation (Custody X Change, 2021).

What parents actually set up: SplitDay's own data

Our own 2026 custody split study of 804 families in 30+ countries setting up a custody calendar found: 42% choose a 50/50 split (the single most common choice), fathers pick equal time more often than mothers (53% vs 38%), 46% of families need a fully custom weekly schedule rather than any standard template, and "keeping track of the schedule" is the #1 reported co-parenting challenge (77%). If you're building your own arrangement, start with the custody schedule maker guide or the 50/50 schedule overview.
