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

Shared custody is now common but far from universal: it rose from 13% of US divorces before 1985 to 34% in 2010–2014, while 78.2% of the 13.9 million US custodial parents in 2022 were still mothers. Internationally the spread is wide — roughly 45% of Swedish children with separated parents alternate between two homes, Spain awarded shared custody in 49.7% of 2024 divorces, and Germany sits at about 8%. Where the research is clearest is on outcomes: a 2018 review of 60 studies found children in joint physical custody did better than sole-custody peers in 34 studies and worse in only 6.

Every figure on this page is linked to its primary source — the US Census Bureau, Eurostat, national statistics offices and peer-reviewed journals — alongside original data from SplitDay's own 2026 custody-setup study of 804 families.

Key facts: custody statistics for 2026

Each figure below is the latest available release from its named source. Page compiled 7 July 2026, sources last re-checked 25 August 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%. We line these national figures up against court records and our own calendar data in a fuller look at which countries choose 50/50 most.

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.

Fresh usage insights (updated August 2026)

Three of those measures have since been re-run on a longer window — 27 April to 23 August 2026 — using the identical method. Both values and both sample sizes are shown, because the refresh supplements the published study rather than replacing it. The headline equal-time figure remains 42% (n=804) and is deliberately not refreshed: the longer window shows a movement we have not yet explained, and the confirmed number is the one worth citing.

• Equal time is largely a national variable. 63% of separated parents setting up a calendar in Spain choose 50/50, against 31% in Germany and 29% in Brazil — a 34-point spread measured the same way, with the same country ranking as the published study on a sample 1.5–2× larger (n=32–204 per country). These gaps track national legal defaults and cultural norms around shared residence, not parental commitment.
• Most families still do not use a standard schedule. 43.4% built a fully custom weekly pattern rather than any named template (n=1,158 pattern selections, April–August 2026), against the published 46% (n=665).
• Keeping track of the schedule remains the hardest part by a factor of two. 74.7% of parents name it, against 35.6% for communication with the other parent (n=1,425 parents, April–August 2026), against the published 77% and 40% (n=655). The rank order of all seven challenges is unchanged.

Method: anonymized, aggregated counts of pre-defined in-app events from parents who consented to analytics; one family counted once, final choice kept; no names, messages, calendar contents or free text are accessed; groups under 30 families are suppressed. First-party product data, not a probability sample — it records what parents set up, which is not always identical to a court order. Full method and the downloadable dataset are on the study page.
