As of 2010, Christianity was the religion with the most followers worldwide, followed by Islam (Muslims) and Hinduism. In the forty years between 2010 and 2050, it is projected that the landscape of world religions will undergo some noticeable changes, with the number of Muslims almost catching up to Christians. The changes in population sizes of each religious group is largely dependent on demographic development, for example, the rise in the world's Christian population will largely be driven by population growth in Sub-Saharan Africa, while Muslim populations will rise across various regions of Africa and South Asia. As India's population is set to grow while China's goes into decline, this will be reflected in the fact that Hindus will outnumber the unaffiliated by 2050. In fact, India may be home to both the largest Hindu and Muslim populations in the world by the middle of this century.

From 2022 to 2060, the worldwide population of Muslims is expected to increase by **** percent. For the same period, the global population of Buddhists is expected to decrease by **** percent.

In 2020, Indonesia recorded the largest population of Muslims worldwide, with around 239 million. This was followed with around 226.88 million Muslims in Pakistan and 213 million Muslims in India.

This statistic shows the top 25 countries in the world with the largest number of Christian population in 2010. In 2010, the United States was leading the ranking with about 243 million Christians living in the country.

These were the highest percentages on the continent. However, also in many other African nations, the majority of the population was Muslim. In Egypt, for instance, Islam was the religion of 79 percent of the people. Islam and other religions in Africa Africa accounts for an important share of the world’s Muslim population. As of 2019, 16 percent of the Muslims worldwide lived in Sub-Saharan Africa, while 20 percent of them lived in the Middle East and North Africa (MENA) region. Together with Christianity, Islam is the most common religious affiliation in Africa, followed by several traditional African religions.

Sikhism is a religion that originated on the Indian subcontinent during the fifteenth century. Sikhs follow the teachings of 'gurus', who descend from the first guru Guru Naruk who established the faith. Followers of Sikhism are monotheists, believing in only one god, and other core beliefs include the need to meditate, the importance of community and communal living, and the need to serve humanity selflessly (or 'seva'). Sikhism and the British Empire In total, there are around 26 million Sikhs worldwide, and over 24 million of these live in India. Outside of India, the largest Sikh populations are mostly found in former territories of the British Empire - the UK and Canada both have Sikh populations of over half a million people. Migration from India to other parts of the British Empire was high in the 19th century, due to the labor demands of relatively newer colonies, as well as those where slavery had been abolished. These countries also remain popular destinations for Sikh migrants today, as many are highly trained and English-speaking. Other regions with significant Sikh populations Italy also has a sizeable Sikh population, as many migrated there after serving there in the British Army during WWI, and they are now heavily represented in Italy's dairy industry. The Sikh population of Saudi Arabia is also reflective of the fact that the largest Indian diaspora in the world can now be found in the Middle East - this is due to the labor demands of the fossil fuel industries and their associated secondary industries, although a large share of Indians in this part of the world are there on a temporary basis.

The purpose of the study: to explore the attitudes of Lithuanian population towards the development of European identity and citizenship in the context of EU change and enlargement. Major investigated questions: respondents were asked whether they support Lithuania's membership in the EU and how membership in this organisation brings benefits and disadvantages to Lithuania. They were asked whether they voted in the European Parliament elections and whether they often watch TV, listen to the radio or read daily newspapers to find out about political news. Next, they were asked to rate the influence of different people on important national issues (ordinary citizen; Member of the European Parliament - 11 choices in total). The survey went on to analyse whether it is more important to grow a competitive European economy within global markets or to ensure better social protection for all its citizens. They were asked to reveal the extent to which they associate themselves with their region, their country or Europe (EU). Given the block of questions, they were asked what it means to be Lithuanian (to be Christian; to follow Lithuanian cultural traditions - 8 choices in total). Given the list of threats, they were asked to rate the risk those threats pose to the EU (non-EU immigrants; EU expansion by including Turkey - 5 choices in total). Respondents had the opportunity to assess European unification and to indicate what it means to be European (being a Christian; following the European cultural traditions - 8 choices in total). Then, trust in the EU and in the ability of Lithuanian institutions to take the right decisions was assessed. The aim was to find out whether respondents felt that decision-makers at the EU level did not take Lithuania's interests into account sufficiently, and whether the interests of some EU Member States were given too much weight. The survey went on to analyse whether different policy areas should be dealt with at the national level or EU level (fight against unemployment; immigration policy [from non-EU countries] - 8 choices in total). Given the next set of questions, respondents were asked what the EU will look like in 10 years (unified EU tax system; mutual social security system - 4 choices in total). Next, they were asked how satisfied they are with the way democracy works in the EU and Lithuania. The survey went on to analyse whether the European Commission should be politically accountable to the European Parliament. Given another block of statements, respondents were asked whether or not different EU policies pose a risk to Lithuania (5 choices in total). Next, the survey went on to assess whether the redistribution of resources between EU Member States to protect the single currency is fair. Respondents were asked whether there should be a mutual EU army or whether each EU Member State should have its national army, and which institution is best suited to take care of Europe's security. Respondents were asked whether they were personally content with the introduction of the euro in Lithuania in 2015 and to describe their political views on a left-right scale. While having the future of the EU in mind, respondents were asked what the EU economy, the economic disparities between EU member states, the social disparities between EU citizens, the importance of the EU as a geopolitical power in the world and what the EU politically will be like in 10 years. The survey was concluded by asking whether or not Lithuania has benefited from EU membership.

The two countries with the greatest shares of the world's Jewish population are the United States and Israel. The United States had been a hub of Jewish immigration since the nineteenth century, as Jewish people sought to escape persecution in Europe by emigrating across the Atlantic. The Jewish population in the U.S. is largely congregated in major urban areas, such as New York, Los Angeles, and Chicago, with the New York metropolitan area being the city with the second largest Jewish population worldwide, after Tel Aviv, Israel. Israel is the world's only officially Jewish state, having been founded in 1948 following the first Arab-Israeli War. While Jews had been emigrating to the holy lands since the nineteenth century, when they were controlled by the Ottoman Empire, immigration increased rapidly following the establishment of the state of Israel. Jewish communities in Eastern Europe who had survived the Holocaust saw Israel as a haven from persecution, while the state encouraged immigration from Jewish communities in other regions, notably the Middle East & North Africa. Smaller Jewish communities remain in Europe in countries such as France, the UK, and Germany, and in other countries which were hotspots for Jewish migration in the twentieth century, such as Canada and Argentina.

In 2021, 53.3 percent of the total population in Canada were Christian, 4.9 percent were Muslim, but almost more than a third are not religious at all – with the rest stating they adhere to Hinduism, Sikhism, Buddhism, the Jewish faith, and other Christian denominations. Canada’s religious pluralismCanada is not a very religious country in general. Canadians adhere to a wide variety of beliefs and faiths, with the majority following Christianity, followed by those who do not believe in any deity or religion at all. As with many Western countries, the younger generations are less inclined to identify with faith, and Christianity in particular is not as popular as it is among the older generations. Alternative worship for the younger generations?Canadian teenagers are no less enthusiastic about religion than their parents, and they are just as grounded in their faith as the older generations. They are, however, also just as indecisive when it comes to whether they would call themselves religious or not. Interestingly, they seem much more interested in traditional aboriginal spirituality than in the Judeo-Christian model. They also seem quite interested in another alternative to Christianity: Buddhism is quite popular among the younger generations. Whether this signifies a general trend away from Christianity and towards religious alternatives remains to be seen.

It was estimated that by 2050, India's Muslim population would grow by ** percent compared to 2010. For followers of the Hindu faith, this change stood at ** percent.
