Religious Belief in Ireland Today (Leaving Cert Religious Education): Revision Notes
Religious Belief in Ireland Today
What you need to know
The Leaving Certificate requires you to understand how religious belief has changed in modern Ireland. You'll need to:
- Identify current patterns of religious affiliation across the population
- Recognise how belief has shifted over time, especially since 2011
- Compare different age groups and regions to understand variation
- Distinguish between religious identity (what people call themselves) and religious practice (what they actually do)
- Use Census data and survey evidence to support your points
Ireland's religious landscape in 2022
The most recent Census data from 2022 reveals significant changes in how Irish people identify religiously. While Ireland remains predominantly Catholic, this majority is shrinking rapidly.
The Catholic decline of 9 percentage points since 2016 represents the steepest fall in modern census history. This dramatic shift marks a turning point in Irish religious identity.
Key Census 2022 findings:
- Roman Catholic: 69% of the population (3.5 million people) - down dramatically from 78% in 2016
- No religion: 14% (736,000 people) - up from 10%, making it the second-largest category
- Church of Ireland: 2.5% with slight growth
- Orthodox Christian: 2% - growth linked to Eastern European migration
- Islam: 1.6% - significant expansion due to immigration
- Hinduism: 0.7% - also growing through immigration
The "no religion" category has more than doubled since 2011, reflecting a broader move towards secularisation. Immigration has made Ireland more religiously diverse, with Orthodox Christianity, Islam, and Hinduism all experiencing notable growth.
Age differences in religious belief
Census data shows clear generational divides that reveal how religious transmission is changing across different age groups.
Age-Based Religious Identity Patterns:
Young adults (25-29 years):
- 53% identify as Catholic
- 26% report no religion
Children's religious identity:
- Ages 0-4: 65% Catholic, 16% no religion
- Ages 5-9: 72% Catholic, 13% no religion
This shows young adults are far less likely to maintain Catholic identity compared to older generations.
These patterns suggest religious identity is being passed on less strongly from parents to children, particularly in urban and younger families. Several factors contribute to this trend:
- Families increasingly adopt secular lifestyles where religion plays a smaller role in daily upbringing
- Children have greater exposure to diverse worldviews through media, education and social connections
- The Catholic Church's declining influence in schools and public life reduces religious socialisation
- Historical abuse scandals have damaged trust in religious institutions among many parents
Regional variations
Religious affiliation varies significantly across Ireland's counties and demonstrates a clear urban-rural divide.
Geographic Patterns of Religious Belief:
Highest Catholic areas:
- Mayo leads with 80% Catholic identification
- Rural counties generally maintain stronger Catholic affiliation
Lowest Catholic areas:
- Dublin City has only 53% Catholic identification
- Urban areas show greater religious diversity
"No religion" patterns:
- Highest in Dún Laoghaire-Rathdown (24%)
- Lowest in rural counties like Monaghan (7%)
Urban areas like Dublin demonstrate greater religious diversity and higher rates of non-religious identification. This reflects more secular lifestyles and the concentration of immigrants from various faith backgrounds. Rural counties maintain higher Catholic affiliation due to stronger community ties to parish life and less exposure to religious diversity in daily life.
The gap between identity and practice
An important distinction exists between religious identity (measured by the Census) and actual religious practice (measured by surveys). This concept is crucial for understanding modern Irish religiosity.
Many people still consider themselves religiously affiliated but engage less frequently in public worship. This gap indicates religion functions more as cultural heritage rather than active spiritual practice.
Research from the European Social Survey and Pew Research shows:
Religious attendance patterns:
- Around 33% of Irish adults attend religious services monthly - one of the highest rates in Western Europe
- Weekly attendance is much lower among younger adults, sometimes dropping below 10% in urban areas
- Private prayer remains common, especially among older people
This occurs because people may value religion as cultural heritage rather than active spiritual practice, or because they prefer private forms of devotion over organised church activities.
Long-term trends and changes
Several major trends characterise religious change in Ireland over recent decades:
Catholic decline: Long-term reduction in Catholic affiliation since the 1960s, with particularly rapid decline since 2011.
Secularisation growth: The "no religion" category has grown sharply, especially among under-40s.
Minority faith expansion: Eastern European Orthodox Christians, South Asian Hindus, and Muslim communities have increased due to migration patterns.
The decline in Catholic identification connects to broader secularisation, cultural change, and reduced social pressure to maintain religious identity. The growth in minority faiths reflects Ireland's transformation into a more multicultural society, particularly since the late 1990s.
Why these changes are happening
Multiple interconnected factors explain Ireland's changing religious landscape, creating a complex web of social transformation.
Key Factors Driving Religious Change:
Secularisation: Religion has become less central to law, politics, and education compared to previous decades. The state has reduced religious influence in public institutions.
Institutional scandals: Clerical abuse revelations and institutional mistreatment have severely damaged the moral authority of religious organisations, particularly the Catholic Church.
Social liberalisation: Legal changes including divorce legalisation, same-sex marriage (2015), and abortion access (2018) reflect increasingly liberal social values that often conflict with traditional religious teachings.
Additional contributing factors include:
Immigration: New communities have brought religious diversity while revitalising some smaller Christian denominations like Orthodox Christianity.
Education and media access: Greater exposure to alternative beliefs and lifestyles through education and media makes non-religious choices more socially acceptable.
Cultural individualisation: Modern Irish society emphasises personal choice and individual autonomy over traditional community and institutional authority.
Comparing local and national patterns
Students may conduct local surveys to compare their community with national trends. Understanding these comparisons helps analyse how broader social changes manifest at local levels.
When analysing local data, consider:
- How your school or community's religious affiliation compares with Census figures
- Whether urban or rural location affects local patterns
- How age profiles and cultural influences shape local religious identity
- What factors might explain differences from national averages
Such comparisons help understand how broader social trends manifest differently across Ireland's diverse communities.
Key Points to Remember:
- Ireland remains majority Catholic (69%) but this is declining rapidly - the steepest drop occurred between 2016-2022
- "No religion" is now the second-largest category nationally at 14% and growing fastest among young people
- Clear demographic divides exist - young people and urban residents are significantly less religious in both identity and practice than older and rural populations
- Immigration has increased religious diversity while secularisation, scandals, and social change have reduced traditional Catholic dominance
- Always support your points with specific Census figures and explain the reasons behind patterns rather than just describing the statistics
