This statistic shows the evolution of affiliation to different religiouns in Russia between 2010 and 2050. In 2010, over 70 percent of the Russian population identified themselves as Christians. However, this amount is expected to shrink gradually in the coming years. Muslims were the second largest group of believers after Christians and their number is expected to grow steadily. Christianity is still forecast to be the strongly dominant religion of the country.

The Finnish Constitution guarantees freedom of religion and freedom of conscience. More than 65 percent of the inhabitants in Finland were part of the Christian community in 2023. The largest Christian community in Finland is the Evangelical Lutheran Church, followed by the Orthodox Church. However, around 1.88 million people were not members of any religious community. People from other religious groups amounted to roughly 20,500, followed by 24,057 from the Muslim community.

Immigration to Finland

While the number of immigrants to Finland remained below 35 thousand in the past decade, this number has started to increase noticeably since 2021. As of 2022, almost 50 thousand people immigrated to Finland, almost 73 percent more compared to the previous year. The significant increase in immigrants was caused by the Russian invasion of Ukraine which started on February 24, 2022. That year, over six thousand people immigrated to Finland from Russia, over twice as many as in the previous year.

The Finnish population is aging

While the number of individuals belonging to the younger age groups in Finland declined from 2018 to 2023, the age group of 60 years and older continued to increase. By the end of 2023, its size was over 1.6 million. The growing number of individuals aged 60 or older reflects the change towards an older population structure of the country. In total, the population of Finland amounted to roughly 5.6 million as of 2023. The largest age groups were 20- to 39-year-olds, and 40- to 59-year-olds, which together made up over half of the population.

The world's Jewish population has had a complex and tumultuous history over the past millennia, regularly dealing with persecution, pogroms, and even genocide. The legacy of expulsion and persecution of Jews, including bans on land ownership, meant that Jewish communities disproportionately lived in urban areas, working as artisans or traders, and often lived in their own settlements separate to the rest of the urban population. This separation contributed to the impression that events such as pandemics, famines, or economic shocks did not affect Jews as much as other populations, and such factors came to form the basis of the mistrust and stereotypes of wealth (characterized as greed) that have made up anti-Semitic rhetoric for centuries. Development since the Middle Ages The concentration of Jewish populations across the world has shifted across different centuries. In the Middle Ages, the largest Jewish populations were found in Palestine and the wider Levant region, with other sizeable populations in present-day France, Italy, and Spain. Later, however, the Jewish disapora became increasingly concentrated in Eastern Europe after waves of pogroms in the west saw Jewish communities move eastward. Poland in particular was often considered a refuge for Jews from the late-Middle Ages until the 18th century, when it was then partitioned between Austria, Prussia, and Russia, and persecution increased. Push factors such as major pogroms in the Russian Empire in the 19th century and growing oppression in the west during the interwar period then saw many Jews migrate to the United States in search of opportunity.

The article discusses the general patterns of development of physical culture, sports and their impact on the spiritual and moral education of the population in Russia. Particular attention is paid to the stages of spiritual and moral education. Each stage is fundamentally invariant, the mechanisms and structures of transitions from one level to another are also identical. The process of such transition is the result of the motivation of human social activity; the formation of the dispositional structure of the personality or the transformation of its interests into a specific goal. The historical process of formation of the educational system takes as a basis the harmonious development of the individual.

The article analyzes ecological problems associated with religion and faith, which is especially noticeable among the inhabitants of megacities. It is shown that in order to preserve nature, it is necessary to include environmental education in the priority tasks of universal education. Particular attention is drawn to different approaches to environmental problems.

During the eighteenth century, it is estimated that France's population grew by roughly fifty percent, from 19.7 million in 1700, to 29 million by 1800. In France itself, the 1700s are remembered for the end of King Louis XIV's reign in 1715, the Age of Enlightenment, and the French Revolution. During this century, the scientific and ideological advances made in France and across Europe challenged the leadership structures of the time, and questioned the relationship between monarchial, religious and political institutions and their subjects. France was arguably the most powerful nation in the world in these early years, with the second largest population in Europe (after Russia); however, this century was defined by a number of costly, large-scale conflicts across Europe and in the new North American theater, which saw the loss of most overseas territories (particularly in North America) and almost bankrupted the French crown. A combination of regressive taxation, food shortages and enlightenment ideologies ultimately culminated in the French Revolution in 1789, which brought an end to the Ancien Régime, and set in motion a period of self-actualization.

War and peace

After a volatile and tumultuous decade, in which tens of thousands were executed by the state (most infamously: guillotined), relative stability was restored within France as Napoleon Bonaparte seized power in 1799, and the policies of the revolution became enforced. Beyond France's borders, the country was involved in a series of large scale wars for two almost decades, and the First French Empire eventually covered half of Europe by 1812. In 1815, Napoleon was defeated outright, the empire was dissolved, and the monarchy was restored to France; nonetheless, a large number of revolutionary and Napoleonic reforms remained in effect afterwards, and the ideas had a long-term impact across the globe. France experienced a century of comparative peace in the aftermath of the Napoleonic Wars; there were some notable uprisings and conflicts, and the monarchy was abolished yet again, but nothing on the scale of what had preceded or what was to follow. A new overseas colonial empire was also established in the late 1800s, particularly across Africa and Southeast Asia. Through most of the eighteenth and nineteenth century, France had the second largest population in Europe (after Russia), however political instability and the economic prioritization of Paris meant that the entire country did not urbanize or industrialize at the same rate as the other European powers. Because of this, Germany and Britain entered the twentieth century with larger populations, and other regions, such as Austria or Belgium, had overtaken France in terms of industrialization; the German annexation of Alsace-Lorraine in the Franco-Prussian War was also a major contributor to this.

World Wars and contemporary France

Coming into the 1900s, France had a population of approximately forty million people (officially 38 million* due to to territorial changes), and there was relatively little growth in the first half of the century. France was comparatively unprepared for a large scale war, however it became one of the most active theaters of the First World War when Germany invaded via Belgium in 1914, with the ability to mobilize over eight million men. By the war's end in 1918, France had lost almost 1.4 million in the conflict, and approximately 300,000 in the Spanish Flu pandemic that followed. Germany invaded France again during the Second World War, and occupied the country from 1940, until the Allied counter-invasion liberated the country during the summer of 1944. France lost around 600,000 people in the course of the war, over half of which were civilians. Following the war's end, the country experienced a baby boom, and the population grew by approximately twenty million people in the next fifty years (compared to just one million in the previous fifty years). Since the 1950s, France's economy quickly grew to be one of the strongest in the world, despite losing the vast majority of its overseas colonial empire by the 1970s. A wave of migration, especially from these former colonies, has greatly contributed to the growth and diversity of France's population today, which stands at over 65 million people in 2020.

In 1800, the population of the modern-day territory of Iran was approximately 6.3 million. This figure would see modest growth throughout the 19th century, as several wars and a mass famine in 1870-1871 (modern estimates put its death toll at around 1.5 million people) were largely balanced out by a surge in migration to Iran; this migration came as the Russian Empire expanded into the Caucuses, and caused a wave of refugees to flee southwards to avoid forced expulsion and ethnic cleansing in the North Caucasus region, particularly from 1864 onwards. As a result, the population of Iran reached ten million by the turn of the 20th century.

Twentieth century growth Iran’s population would begin to grow rapidly in the 20th century, as the discovery of oil in the country in 1908 led to an economic boom, and the socio-economic reforms implemented under Reza Shah would see a number of medical and healthcare advancements across the country. Although unpopular with religious fundamentalists, Reza Shah's reforms had long-term influence on the demographic development of Iran, even after his abdication in 1941. Following the Second World War, Iran became increasingly westernized and developed relatively strong relations with the U.S.; however, western influence, economic imbalances and the oppression of the Mohammed Reza Shah's regime became the driving forces behind the Iranian Revolution, which was one of the most significant moments in the history of the region.

Growth after the Revolution The 1979 Iranian Revolution saw the removal of the Shah and an end to Iran's so called westernization; the monarchy was replaced by an Islamic, theocratic regime led by the Supreme Leader, Ayatollah Ruhollah Khomeini. During Khomeini's decade in charge he oversaw Iran's transition into an Islamic Republic, which implemented radical political and cultural changes in the country, and this coincided with an increased population growth rate in the 1980s. This growth was promoted by the Iranian government, who encouraged a baby boom during the Iran–Iraq War between 1980 and 1988, as part of an effort to increase future Iranian military manpower. As a result of this strategy, the population of Iran would grow from approximately 38.6 million in 1980 to over 56 million just a decade later. Following the implementation of a UN-brokered ceasefire in 1988, population growth in Iran would slow, as economic sanctions and government implementation of family planning policies would lead to a drop in fertility. Population growth has continued steadily into the 21st century, however, and in 2020, Iran is estimated to have a population of 84 million.

Throughout the 19th century, what we know today as Poland was not a united, independent country; apart from a brief period during the Napoleonic Wars, Polish land was split between the Austro-Hungarian, Prussian (later German) and Russian empires. During the 1800s, the population of Poland grew steadily, from approximately nine million people in 1800 to almost 25 million in 1900; throughout this time, the Polish people and their culture were oppressed by their respective rulers, and cultural suppression intensified following a number of uprisings in the various territories. Following the outbreak of the First World War, it is estimated that almost 3.4 million men from Poland served in the Austro-Hungarian, German and Russian armies, with a further 300,000 drafted for forced labor by the German authorities. Several hundred thousand were forcibly resettled in the region during the course of the war, as Poland was one of the most active areas of the conflict. For these reasons, among others, it is difficult to assess the extent of Poland's military and civilian fatalities during the war, with most reliable estimates somewhere between 640,000 and 1.1 million deaths. In the context of present-day Poland, it is estimated that the population fell by two million people in the 1910s, although some of this was also due to the Spanish Flu pandemic that followed in the wake of the war.

Poland 1918-1945

After more than a century of foreign rule, an independent Polish state was established by the Allied Powers in 1918, although it's borders were considerably different to today's, and were extended by a number of additional conflicts. The most significant of these border conflicts was the Polish-Soviet War in 1919-1920, which saw well over 100,000 deaths, and victory helped Poland to emerge as the Soviet Union's largest political and military rival in Eastern Europe during the inter-war period. Economically, Poland struggled to compete with Europe's other powers during this time, due to its lack of industrialization and infrastructure, and the global Great Depression of the 1930s exacerbated this further. Political corruption and instability was also rife in these two decades, and Poland's leadership failed to prepare the nation for the Second World War. Poland had prioritized its eastern defenses, and some had assumed that Germany's Nazi regime would see Poland as an ally due to their shared rivalry with the Soviet Union, but this was not the case. Germany invaded Poland on September 1, 1939, in the first act of the War, and the Soviet Union launched a counter invasion on September 17; Germany and the Soviet Union had secretly agreed to do this with the Molotov-Ribbentrop Pact in August, and had succeeded in taking the country by September's end. When Germany launched its invasion of the Soviet Union in 1941 it took complete control of Poland, which continued to be the staging ground for much of the fighting between these nations. It has proven difficult to calculate the total number of Polish fatalities during the war, for a variety of reasons, however most historians have come to believe that the figure is around six million fatalities, which equated to almost one fifth of the entire pre-war population; the total population dropped by four million throughout the 1940s. The majority of these deaths took place during the Holocaust, which saw the Nazi regime commit an ethnic genocide of up to three million Polish Jews, and as many as 2.8 million non-Jewish Poles; these figures do not include the large number of victims from other countries who died after being forcefully relocated to concentration camps in Poland.

Post-war Poland

The immediate aftermath of the war was also extremely unorganized and chaotic, as millions were forcefully relocated from or to the region, in an attempt to create an ethnically homogenized state, and thousands were executed during this process. A communist government was quickly established by the Soviet Union, and socialist social and economic policies were gradually implemented over the next decade, as well as the rebuilding, modernization and education of the country. In the next few decades, particularly in the 1980s, the Catholic Church, student groups and trade unions (as part of the Solidarity movement) gradually began to challenge the government, weakening the communist party's control over the nation (although it did impose martial law and imprison political opponent throughout the early-1980s). Increasing civil unrest and the weakening of Soviet influence saw communism in Poland come to an end in the elections of 1989. Throughout the 1990s, Poland's population growth stagnated at around 38.5 million people, before gradually decreasing since the turn of the millennium, to 37.8 million people in 2020. This decline was mostly due to a negative migration rate, as Polish workers could now travel more freely to Western European countries in search of work, facilitated by Pola...

From 1800 until the late twentieth century, there was a steady increase in Afghanistan's population. Throughout the nineteenth century, Afghanistan became a battleground for the British Empire, who tried to control the area in order to prevent Russian expansion towards the British Raj. Despite resisting the British invasion in the first Anglo-Afghan War, (where the British Army was almost completely wiped out), the Second Anglo-Afghan War in 1880 saw Britain seize control of the region. In contrast to the neighboring colonies on the Indian subcontinent, Britain did not colonize Afghanistan for economic purposes, therefore they did not invest in agriculture or infrastructure, nor introduce medicine in the same way they did in the Raj, and focused only on Afghanistan's international affairs. Independence and progress The Third Anglo-Afghan War, where Afghan forces invaded British India in 1919, resulted in Afghanistan's independence finally being declared after two months of conflict. The next decade saw some major reforms that attempted to modernize Afghan society, (notable progress was made for women's rights and education) however this alienated many conservative and religious tribes, and a civil war broke out in 1928. After the war (and brief usurpation) the new King of Afghanistan, Nadir Khan, consolidated power, and also moved to modernize the country, but more gradually than his predecessors in order to avoid further alienation and conflict. Khan's approach remained in place until the 1970s, when a bloodless coup established a republic. The republic never achieved political stability, and the Sauri Revolution of 1978 resulted in the formation of the communist Democratic Republic of Afghanistan. Continuous war Despite some progressive reforms, such as banning forced marriages and opening a space for women in politics, the determination to promote state atheism combined with the country's economic dependence on the Soviet Union led to serious opposition from Afghan people, particularly in rural areas. On December 24, 1979, the Soviet Union (backed by the Afghan government) invaded the country, and the ensuing decade-long guerilla war resulted in as many as two million fatalities and three million wounded, as well as two million internally displaced persons and five million refugees abroad. Soviet withdrawal was seen as a western victory, as they had supported the Taliban in their fight against the Soviets, however a decade later the Taliban refused to hand over Osama Bin Laden and other al-Qaeda suspects to the US, following the 9/11 attacks in 2001. This led to US and British forces launching Operation Enduring Freedom in October 2001, and an intensive bombing campaign followed, destroying many major cities in the country. The Taliban government was toppled in December 2001, and in 2002 a western-led rebuilding of the country began. Over the past two decades, many displaced Afghans have returned home, leading to some economic growth, however guerilla fighting continues and there is a strong military presence in the country (including many Taliban controlled areas). In 2020, Afghanistan remains one of the poorest and most politically unstable countries in the world, however the rapid population growth experienced in recent decades is expected to continue well into the future, as improvements in medical care and humanitarian aid become more widespread across the country.
