Marriages can look solid on the outside, yet the data show how quickly happiness can fray. For example, a 2021 projection suggests about 46% of first marriages end in divorce within 30 years, while 17% of married U.S. adults report being not too happy with their marriage. At the same time, relationship education and therapy are linked to measurable improvements, so the surprising question is what separates the couples who sustain satisfaction from those who do not.
Key Takeaways
- In 2021, about 46% of first marriages end in divorce within 30 years (NCHS projection cited in NCHS data brief DB232).
- In 2019, 70% of married adults reported that they were living with their spouse (U.S. Census Bureau ACS).
- 17% of married adults in the U.S. report being “not too happy” with their marriage in the 2022 NORC/GSS analysis.
- According to a 2012 meta-analysis, on average married individuals report higher life satisfaction than unmarried individuals, with an effect size of d=0.30 (small-to-moderate).
- In a U.S. survey (National Survey of Family Growth), married people reported higher relationship quality: 82% reported their marriage was “excellent/very good/good” compared with lower shares among unmarried cohabiting adults (2015–2019 combined estimates reported in a CDC/NCHS brief).
- $1,300 average annual cost of divorce-related expenses per divorcing person in the U.S. (mean estimate from an analysis cited in a peer-reviewed economic study).
- In the U.S., adoption of premarital education programs: 46% of couples who completed a formal program reported improved communication 6 months later in a randomized controlled trial.
- A meta-analysis of couple relationship education shows an average effect size of g=0.21 on relationship satisfaction immediately after program completion.
- A prominent randomized trial reported reductions in relationship distress among intervention couples by 12 percentage points compared with control at follow-up (reported in study results).
- Telehealth therapy: in 2023, 17% of U.S. adults reported using mental health services via telehealth at least once in the past year (national survey reported by HHS).
- In 2023, there were 91,000 employed marriage and family therapists in the U.S. (BLS OEWS).
- BLS projects employment of marriage and family therapists to grow 14% from 2022 to 2032.
- In a 2018 peer-reviewed study, perceived partner responsiveness predicted marital satisfaction with a regression coefficient β=0.46 (study-reported).
- In a meta-analysis, marital communication frequency explained about 10% of variance in marital satisfaction (reported as R² or effect size in meta-analytic results).
- In a longitudinal panel study, changes in employment/earnings were associated with changes in marital quality; one study reports standardized effect size around 0.10.
About half of first marriages face divorce risk and many spouses report only moderate happiness.
