Italy's Religious Landscape: Catholic Dominance, Rising Diversity
Italy remains overwhelmingly Catholic in identity, though practice and belief are diversifying rapidly.
By the Numbers (Estimates)
| Affiliation | Share | Source/Notes |
|---|
| Catholic (identify) | 74–83% | Istat 2021 / CESNUR / Pew 2017 |
| Catholic (weekly Mass) | ~18–22% | Istat / CEI — steep decline from 60% (1990) |
| Non-religious / Atheist / Agnostic | 15–25% | Rising fast; highest among under-35 |
| Other Christians | ~4–6% | Orthodox (Romanian, Ukrainian), Protestant (Waldensian, Baptist, Pentecostal), JW, LDS |
| Islam | ~3–5% | ~2.5M; mostly immigrants (Morocco, Albania, Bangladesh, Pakistan) + converts |
| Judaism | ~0.05% | ~28,000; Rome, Milan, Turin, Trieste; continuous since 2nd c. BCE |
| Buddhism / Hinduism / Sikhism / Bahá'í | ~1–2% | Immigrant communities + converts |
Structural Factors
- Vatican City — Sovereign enclave in Rome; Pope = Bishop of Rome; global Catholic governance
- Concordat (1929/1984) — Church-state treaty: religious education (optional), 8×1000 tax allocation, canonical marriage recognition
- Cultural Catholicism: Baptism, first communion, marriage, funeral rites remain near-universal social markers
Regional Variation
- South/Islands: Higher Catholic identity, practice
- North/Central: Lower practice, higher "nones"
- Urban vs. rural: Cities more secular
Trends
- Secularization: Baptisms, marriages, vocations declining 2–3%/yr
- Pluralization: Mosques (500+), Buddhist centers, Hindu temples, Sikh gurdwaras
- Legal: Civil unions (2016), advance directives, end-of-life debates challenge Church influence
Italy: Catholic by heritage, plural by trajectory.
