Devout Catholics: A Shrinking Number?

how many devout catholics are there

Catholicism is the second-largest religious body in the world ,with around 1.3 billion believers globally. The number of devout Catholics is difficult to ascertain, as it is a matter of personal interpretation and practice. However, according to various sources, countries like Poland, France, Brazil, and Malta are often mentioned as having a significant number of devout Catholics or a high level of devotion among their Catholic populations. The Catholic Church has experienced growth in certain regions, such as Africa and Asia, while seeing a decline in Europe.

Devout Catholics in the United States

Catholicism is one of the largest religious groups in the United States. It is the largest religious body in 36 states, and about 20% of American adults identify as Catholics. This equates to around 52-53 million Catholic adults out of 262-267 million adults in the U.S. in 2024. This percentage has been stable for the past decade, although it is slightly lower than in 2007, when 24% of U.S. adults identified as Catholic.

The Catholic population in the U.S. is growing, with a rise of about 2 million people in the past 10 years. This growth is concentrated in the South, which now has more Catholics than any other region. In the past, the Northeast and Midwest had the highest number of Catholics, but today, the South and West are experiencing the fastest growth, while the Midwest and Northeast are in decline.

Catholicism was introduced to the United States during the period of European colonization. In the early 19th century, there was a major Catholic revival, known as Ultramontanism, which swept across Europe, North America, and South America. This revival emphasised piety, miracles, saints, and new devotions such as compulsory Sunday attendance, regular confession and communion, praying the rosary, devotion to the Blessed Virgin, and meatless Fridays. It also fostered a deeper respect for bishops and the Pope, with more direct control by the Vatican over bishop selection.

The racial and ethnic makeup of the Catholic population in the U.S. varies by region. Overall, the Catholic population is approximately 54-57% White, 33-36% Hispanic, 4% Asian, and 2% Black, with 2-3% identifying with another race. In the Midwest, 78-80% of Catholics are White and 15-17% are Hispanic, while in the Northeast, 72% are White and 19-20% are Hispanic. The South has the most diverse Catholic population, with 44-49% White, 40-45% Hispanic, and 2% Black. The West has the largest population of Hispanic and Asian Catholics, with 55-58% of Catholics being Hispanic, 27-30% White, and 10% Asian.

Hispanic Catholics tend to be younger than White Catholics, with 70% of White Catholics aged 50 and older, compared to 44-58% of Hispanic Catholics. Asian Catholics also tend to be younger, with only 14% aged 65 and older, versus 39% of White Catholics. More than four-in-ten U.S. Catholics are immigrants (29%) or the children of immigrants (14%).

Mass attendance among Catholics in the U.S. is reported to be around 28%, with larger shares of Catholics praying daily (52%) and considering religion very important in their lives (46%).

France and its devout Catholics

France has a long history of Catholicism, with the religion holding the role of the state religion under the monarchy for over a millennium. The country was known as the "eldest daughter of the Church", indicative of its close ties to the Roman papacy. Despite a shift towards secularism in the 20th century, including the 1905 law on the separation of Church and State, France remains a stronghold for devout Catholics.

Catholicism is the dominant religion in France, with estimates of the proportion of Catholics in the country ranging from 25% to 47% of the population. The higher estimates include lapsed Catholics and "Catholic atheists". Notably, only 8% of Catholics in France regularly attend a place of worship, which may be indicative of a broader cultural identification with Catholicism rather than strict religious observance.

The Catholic Church in France is organised into 98 dioceses, served by around 7,000 priests in 2012. Approximately 45,000 Catholic churches and chapels are spread across the country, although many are no longer regularly used for Mass. The country is also home to several notable Catholic sites, including Notre Dame de Paris, Chartres Cathedral, and the national shrine of Lourdes, which attracts 5 million pilgrims annually.

In recent decades, France has emerged as a hub for the Traditionalist Catholic movement, alongside countries like the United States and England. The Society of Saint Pius X, a canonically irregular priestly society founded by French Archbishop Marcel Lefebvre, has a significant presence in the country. Additionally, the influence of traditionalist priestly societies in full communion with Rome, such as the Priestly Fraternity of St. Peter and the Institute of Christ the King Sovereign Priest, underscores the devotion of France's Catholic population.

While France has a strong secular tradition, with freedom of religion and conscience protected by law, the country's Catholic heritage remains influential. The impact of Catholicism can be seen in various aspects of French culture, from its architecture and art to its social and political history. Despite the decline in religious observance, France continues to be associated with a vibrant and dedicated community of devout Catholics.

Catholicism in Asia

Catholicism has played a significant role in shaping the cultural and religious landscape of Asia, with a history that dates back to the early days of Christianity. While it is often viewed as a minority religion in the region, its impact on local communities and nation-building cannot be overlooked.

One of the earliest instances of Catholicism in Asia can be traced back to the 1st century AD when, according to tradition, the apostle Thomas introduced Christianity to India and the Parthian Empire (Iran). The first nations to adopt Christianity as a state religion were Armenia in 301 and Georgia in 327. By the 4th century, Christianity had become the dominant religion in all Asian provinces of the Eastern Roman Empire.

Over the centuries, the spread of Catholicism in Asia was influenced by various factors, including the expansion of the Roman Empire, the development of Islam, and the missionary efforts of Catholics. During the 7th century, nomadic Turks of Central Asia started to convert to Nestorian Christianity, with mass conversions also occurring among the Turks and Mongols in 781–782 and later in 1007.

In the 16th century, the Portuguese invasion of Ceylon (present-day Sri Lanka) introduced Catholicism to the region. During the same period, hundreds of thousands of Japanese people converted to Catholicism, shaping the self-conception of the diverse societies in the archipelago.

Today, the Philippines has long been considered the most Catholic country in Asia, with 83% of its population identifying as Catholic. However, in recent decades, Timor-Leste has overtaken the Philippines, with 97% of its population practising Catholicism. This recent shift in religious affiliation challenges the notion that religion, particularly Catholicism, is fixed and conservative.

While Catholicism may constitute a small percentage of the overall population in many Asian countries, its impact is significant at the local scale. For instance, regions like Flores in Indonesia and parts of Papua are predominantly Catholic. Similarly, countries like India, Sri Lanka, Vietnam, and Myanmar have regions and cities with a strong Catholic presence, influencing the religious and cultural landscape of these nations.

Catholic demographics in Latin America

Latin America has historically been predominantly Catholic, with the religion influencing the region's laws and politics. However, the number of people identifying as Catholic has been declining, while the number of those identifying as evangelical has been growing.

According to the 2014 Pew Research Center survey, the 46 countries and territories of Latin America and the Caribbean comprised the world's second-largest Christian population (24%). A 2024 survey by M&R Consultadores found that 36.2% of Latin Americans identified as Catholic, 31% as non-denominational believers, and 27.7% as Protestant. The Pew survey also found that 69% of the Latin American population is Catholic, 19% is Protestant, rising to 22% in Brazil and over 40% in much of Central America.

The Latinobarómetro survey found that the percentage of people who identify as Catholic dropped from 70% in 2010 to 57% in 2020, while the number of Latin Americans who said they don't have a religion jumped by six percentage points in the same period. The survey also found that in Brazil, the number of respondents who identified as evangelical rose from 3% in 2000 to 22% in 2020.

The decline in Catholicism in Latin America has been accompanied by a decrease in trust in the Catholic Church, most notably in Argentina and Uruguay, where the Church has been accused of turning a blind eye to past dictatorships' human rights abuses. In Chile, the Church has been embroiled in clergy sex abuse scandals.

Despite the decline, Catholicism remains socially ingrained in Latin American culture, with many still celebrating Catholic traditions like Día de los Reyes Magos (Three Kings Day). Additionally, Latino immigrants to the US are more likely to be Catholic (19% vs. 12% evangelical), and Catholicism remains the largest faith among US Latinos, although it is also declining.

The Vatican's influence

One of the most significant ways the Vatican exerts its influence is through its diplomatic status. The Holy See, as the governing body of the Catholic Church, has diplomatic relations with numerous countries, allowing it to access an extensive international network of charities and humanitarian initiatives. This includes managing 5,000 hospitals, 10,000 orphanages, 95,000 elementary schools, and 47,000 secondary schools worldwide. The Vatican's diplomatic status grants it a unique position in global affairs and enables it to advocate for its interests and those of its followers.

The Vatican also wields considerable soft power through its cultural and spiritual influence. The Catholic Church has a rich history and cultural heritage that shapes the lives of its adherents. Traditions, rituals, and religious holidays are celebrated by Catholics worldwide, fostering a sense of community and shared identity. The Vatican's spiritual teachings and doctrines guide the moral and ethical frameworks of devout Catholics, influencing their values, beliefs, and behaviours. This influence is particularly notable in countries with a strong Catholic presence, such as Poland, Lithuania, Croatia, and Latin American nations, where Catholic culture is deeply woven into the social fabric.

Additionally, the Vatican exerts influence through its leadership and organisational structure. The Pope, as the Bishop of Rome and the head of the Catholic Church, is a highly respected figure with a global following. The Church's hierarchical structure, including cardinals, bishops, priests, and deacons, facilitates the dissemination of teachings and the administration of local parishes. This structure contributes to the Vatican's ability to maintain cohesion and exert influence over its followers.

In conclusion, the Vatican's influence is profound and multifaceted, shaped by the number of devout Catholics worldwide. Its diplomatic status, cultural and spiritual influence, organisational structure, and leadership all contribute to its impact on global affairs and the lives of its followers. While the influence may vary across regions, the Vatican remains a significant force in the lives of Catholics and, by extension, in international relations and cultural dynamics.
