Age, Personality and Life Happiness in Sweden
A recent study examined the drivers of well‑being among 15,068 adults in Sweden using data from a 2023 national survey. Researchers divided the information into three key domains:
- Demographics – age, gender, income
- Psychological traits – the Big Five (neuroticism, extraversion, etc.)
- Social relationships – loneliness, partner love, friendships
Predictive Model
A machine‑learning model was built to estimate an overall happiness score that blends positive feelings (happiness, life balance) with negative ones (depression, anxiety). The model explained about 79 % of the variance in happiness scores—a strong performance for a social‑science study.
Key Findings
- Age emerged as the most influential demographic factor, with a moderate correlation of roughly 0.3 to happiness.
- Psychological indicators—especially neuroticism, loneliness, and relationship satisfaction—remain the strongest predictors.
- Longitudinal data from 2006‑2024 confirm that older Swedes are happier than younger ones, and this age gap has widened in the past five years.
Political Identity Maps
The paper introduces “political identity maps” that illustrate how different demographic groups perceive life. These visual tools could aid lawmakers and the public in targeting resources where they’re most needed.
Takeaway for Policymakers
While personality traits and relationship quality continue to explain the bulk of happiness differences, age is becoming an increasingly important cue. Targeted interventions to support younger Swedes could help narrow the well‑being gap and foster a healthier society.
