In 2020, around 28.8 percent of the global population were identified as Christian. Around 25.6 percent of the global population identify as Muslims, followed by 14.9 percent of global populations as Hindu. The number of Muslims increased by 347 million, when compared to 2010 data, more than all other religions combined.

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.

The World Religion Project (WRP) aims to provide detailed information about religious adherence worldwide since 1945. It contains data about the number of adherents by religion in each of the states in the international system. These numbers are given for every half-decade period (1945, 1950, etc., through 2010). Percentages of the states' populations that practice a given religion are also provided. (Note: These percentages are expressed as decimals, ranging from 0 to 1, where 0 indicates that 0 percent of the population practices a given religion and 1 indicates that 100 percent of the population practices that religion.) Some of the religions (as detailed below) are divided into religious families. To the extent data are available, the breakdown of adherents within a given religion into religious families is also provided.

The project was developed in three stages. The first stage consisted of the formation of a religion tree. A religion tree is a systematic classification of major religions and of religious families within those major religions. To develop the religion tree we prepared a comprehensive literature review, the aim of which was (i) to define a religion, (ii) to find tangible indicators of a given religion of religious families within a major religion, and (iii) to identify existing efforts at classifying world religions. (Please see the original survey instrument to view the structure of the religion tree.) The second stage consisted of the identification of major data sources of religious adherence and the collection of data from these sources according to the religion tree classification. This created a dataset that included multiple records for some states for a given point in time. It also contained multiple missing data for specific states, specific time periods and specific religions. The third stage consisted of cleaning the data, reconciling discrepancies of information from different sources and imputing data for the missing cases.

The Global Religion Dataset: This dataset uses a religion-by-five-year unit. It aggregates the number of adherents of a given religion and religious group globally by five-year periods.

As of 2020, Christianity was the largest religion in the world, with around 2.5 billion believers. In the second place was Islam, with around 1.9 billion adherents.

In 2022, ** percent of Hindus and Buddhists worldwide lived in Asia-Pacific. In comparison, ** percent of Jews lived in North America, and **** percent lived in the Middle East and North Africa. Christians were more evenly divided around the continents.

Among the people surveyed in 26 countries around the world, a slight majority of the baby boomer generation were Christians. By comparison, only 42 percent of Generation Z stated that they were Christians. Millennials was the generation with the highest share of people stating that they had a religious belief other than Islam and Christianity.

Christianity was the largest religion in a high number of the countries included in the survey. Of the countries, Peru, South Africa, and Poland had the highest share of Christians at around 75 percent. Moreover, around 90 percent in India and Thailand stated that they believed in another religion, with Hinduism and Buddhism being the major religion in the two countries respectively. Sweden and South Korea were the only two countries where 50 percent or more of the respondents stated that they did not have any religious beliefs.

Religious adherence varies widely between countries and regions across the globe. While in some countries, such as Bangladesh (majority-Muslim), Thailand (majority-Buddhist), and Nigeria (over 50 percent Muslim and 45 percent Christian), almost all people indicate that religion is important in their daily lives, in others such as Japan, Sweden, and Estonia, over three quarters of people do not believe that religion is important to them. Among countries with higher levels of religious adherence, there are some interesting cases. Predominantly Islamic countries, such as Bangladesh, Indonesia, and Saudi Arabia, tend to show high levels of religious adherence. Italy, the historical center of the Catholic Church, records much higher levels of religiosity than other Western European countries, such as France, Germany, or the UK. The United States has almost double the number of people saying they believe religion is important in their daily life than not important. While religious adherence has declined over the past half century in the U.S., waves of immigration from predominantly Catholic countries, as well as the cultural impact of Evangelical Protestantism in some areas has meant that it is still one of the most religious Western countries. Israel, in spite of being an officially Jewish state, records roughly half of respondents being religious. Another notable trend is the tendency of some post-communist countries to show lower levels of religiosity, likely a result of the policy of state atheism under communism - Russia, Belarus, and Estonia all come towards the least religious end of the list for this reason, although Poland, or former-Soviet states in the Caucuses and Central Asia show much higher levels of religious adherence.

From 2022 to 2060, the worldwide population of Muslims is expected to increase by 45.7 percent. For the same period, the global population of Buddhists is expected to decrease by 12.2 percent.

The Religious Food market, a unique segment within the broader food industry, focuses on food products that adhere to specific religious guidelines and dietary laws. This market encompasses a variety of foods that cater to the dietary restrictions observed by followers of major world religions, including but not lim

In Brazil, 70 percent of the respondents believed in God as described in the holy scriptures, and another 19 percent believed in a higher power or spirit. In South Africa, the figures were 73 and 16 percent respectively. By contrast, less than one in five in Japan and only one in three in South Korea believed in God or some form of spirit or higher power.

Christianity is the major religion in numerous African countries. As of 2024, around 96 percent of the population of Zambia was Christian, representing the highest percentage on the continent. Seychelles and Rwanda followed with roughly 95 percent and 94 percent of the population being Christian, respectively. While these countries present the highest percentages, Christianity was also prevalent in many other African nations. For instance, in South Africa, Christianity was the religion of nearly 85 percent of the people, while the share corresponded to 71 percent in Ghana. Religious variations across Africa Christianity and Islam are the most practiced religions in Africa. Christian adherents are prevalent below the Sahara, while North Africa is predominantly Muslim. In 2020, Christians accounted for around 60 percent of the Sub-Saharan African population, followed by Muslims with a share of roughly 30 percent. In absolute terms, there were approximately 650 million Christians in the region, a number forecast to increase to over one billion by 2050. In contrast, Islam is most prevalent in North Africa, being the religion of over 90 percent of the population in Algeria, Morocco, Tunisia, and Libya. Christianity in the world As opposed to other religions, Christianity is widely spread across continents worldwide. In fact, Sub-Saharan Africa, Latin America and the Caribbean, and Europe each account for around 25 percent of the global Christian population. By comparison, Asia-Pacific and North America make up 13 percent and 12 percent of Christians worldwide, respectively. In several regions, Christians also suffer persecution on religious grounds. Somalia and Libya presented the most critical situation in Africa in 2021, reporting the strongest suppression of Christians worldwide just after North Korea and Afghanistan.

Null Hypotheses (H-not/H0) :- Are religious people more happy, and does it contribute to a better experience of life? ----------------------AND in the same vein ---------------------------------------------------------------------- Is the increasing trend of Atheism directly related to increasing reported levels of ADHD, depression and suicide rates around the world?

The research :- A slew of research suggests that religious people are happier, are better at keeping family ties, contribute to society more by being involved in the community, report better life experience and are better able to cope with life's setbacks like Divorce. Is this true? Below is a random list of research I found from googling :-

What the Quran says :- Having graduated from the London School of Economics (2004, Bsc Hons) and having been greatly influenced by Richard Dawkins, books like "The God Delusion" etc. for about 7 years and seeking extensively through the various religious/self development traditions including Judaism, Christianity, Buddhism, Hinduism, The Landmark Forum and Tai Chi, I converted to Islam 4 years ago. I can personally attest to having a much greater experience of life and feeling peace and tranquility and calmness in my heart. In the Sufi tradition, the heart is the kernel of connecting to God (Allah), and the seat of God consciousness :- https://www.youtube.com/watch?v=nqNPVP6GerM&index=1&list=PLwFLXkJiBtuza1uSJHsB8MJCfQ9l7h8jf

Allah says in the Quran :- "And whoever turns away from My remembrance - indeed, he will have a depressed life,...." [Quran 20:124]

And Allah also says in the Quran :- "Those who have believed and whose hearts are assured by the remembrance of Allah. Unquestionably, by the remembrance of Allah hearts are assured." [Quran 13:28]

Dataset :- The data set regarding population is the gross population by country taken from the World Bank Data Site, link here :- https://data.worldbank.org/indicator/SP.POP.TOTL?locations=US&view=chart

Can you :- Look at populations around the world using the dataset, and look at suicide levels, depression levels, reported ADHD levels, and anxiety levels and find a correlation between the increasing trend of atheism in the world and these reported markers.
