In 2023, 40-59-year-olds made up the largest age group in Germany, at almost 23 million people. The most recent figures confirm that the next-largest age group was 65 years and older, at 18.89 million. Aging population With the number of people belonging to older age groups visibly outstripping younger ones, in recent years it has become clear that Germany’s population is aging. In fact, figures on age structure in Germany depict a constant trend of a slowly increasing population share aged over 65 since 2012. Meanwhile, the share of population members aged 0 to 14 years has been falling, which was also reflected in the fluctuating national birth rate in recent years. A look at the future Germany’s current total population stands at 84.7 million. While this number is predicted to increase, the same goes for the age group of 65 years and older. This means that the national population will continue to age.

In 2023, the population share with a migrant background in the wider sense was almost 30 percent. According to the source, a person is considered to have a migrant background when they or at least one parent do not have German citizenship by law. This definition includes the following:1. Immigrated and non-immigrated foreigners.2. Immigrated and non-immigrated naturalized citizens.3. Late emigrants.4. Descendants born with German citizenship within the three groups named above.

Census data reveals that population density varies noticeably from area to area. Small area census data do a better job depicting where the crowded neighborhoods are. In this map, the yellow areas of highest density range from 30,000 to 150,000 persons per square kilometer. In those areas, if the people were spread out evenly across the area, there would be just 4 to 9 meters between them. Very high density areas exceed 7,000 persons per square kilometer. High density areas exceed 5,200 persons per square kilometer. The last categories break at 3,330 persons per square kilometer, and 1,500 persons per square kilometer.This dataset is comprised of multiple sources.

ALLBUS (GGSS - the German General Social Survey) is a biennial trend survey based on random samples of the German population. Established in 1980, its mission is to monitor attitudes, behavior, and social change in Germany. Each ALLBUS cross-sectional survey consists of one or two main question modules covering changing topics, a range of supplementary questions and a core module providing detailed demographic information. Additionally, data on the interview and the interviewers are provided as well. Key topics generally follow a 10-year replication cycle, many individual indicators and item batteries are replicated at shorter intervals.

Since the mid-1980ies ALLBUS also regularly hosts one or two modules of the ISSP (International Social Survey Programme).

The main topic of ALLBUS/GGSS 1996 is attitudes towards different ethnic groups in Germany (with questions on the perception of ethnic groups, social distance, prejudicial attitudes, and potential determinants of such attitudes). Other topics include attitudes toward family, marriage and partnership, national pride, trust (in fellow citizens and politicians), and attitudes towards abortion. Additionally included is the ISSP module "Role of Government III."

Contained within the 1st Edition (1906) of the Atlas of Canada is a plate that shows two maps. The first map that shows origins of the people in Maritime provinces and Eastern Quebec, circa 1901. The second map that shows origins of the people in Quebec and Ontario, circa 1901.A varying number of ethnic groups are shown, but mainly: English, Scotch [Scottish], Irish, French and German. People of British origin predominate all provinces, except Quebec, where the French predominated. The French also predominate in adjacent portions of Quebec, such as portions of eastern Ontario, northern New Brunswick, southwestern Nova Scotia, and in the southern portion of Cape Breton. In two small areas near Halifax, N.S., the map indicates descendants of deported persons from Jamaica. The Germans were principally descendants of United Empire Loyalists predominating portions of southern Nova Scotia, Waterlook, Lincoln and Welland counties. Communities with a population greater than 5000 people are shown as proportional dots on the map. In addition, major railway systems displayed.

The largest number of immigrants in Germany were from Ukraine, as of 2023. The top three origin countries were rounded up by Romania and Turkey. Immigrants are defined as having left a country, which may be their home country, to permanently reside in another. Upon arriving, immigrants do not hold the citizenship of the country they move to. Immigration in the EU All three aforementioned countries are members of the European Union, which means their citizens have freedom of movement between EU member states. In practice, this means that citizens of any EU member country may relocate between them to live and work there. Unrestricted by visas or residence permits, the search for university courses, jobs, retirement options, and places to live seems to be defined by an enormous amount of choice. However, even in this freedom of movement scheme, immigration may be hampered by bureaucratic hurdles or financial challenges. Prosperity with a question mark While Germany continues to be an attractive destination for foreigners both in and outside the European Union, as well as asylum applicants, it remains to be seen how current events might influence these patterns, whether the number of immigrants arriving from certain countries will shift. Europe’s largest economy is suffering. Climbing inflation levels in the last few months, as well as remaining difficulties from the ongoing coronavirus (COVID-19) pandemic are affecting global economic development. Ultimately, future immigrants may face the fact of moving from one struggling economy to another.

Parameter estimates of the 2-class choice model for 2015.

From 1273 until 1918, Austria was the seat of power of the House of Habsburg; one of Europe's most powerful and influential royal families of the past millennium. During this time and in the subsequent century since the Austro-Hungarian Empire's dissolution, the borders and demography of the Austrian state have changed dramatically, with the population growing from approximately three million people in 1800 to just over nine million in 2020. The area of modern Austria's population rose gradually throughout the nineteenth century, until the early 1900s, where it then dropped and fluctuated during the World Wars, before rising again until recent years.

End of an empire

The assassination of the heir to the Austrian throne, Archduke Franz Ferdinand, in Sarajevo on June 28, 1914, caused Austria to declare war on Serbia, which marked the outbreak of the First World War. The war (and subsequent Spanish Flu pandemic) would see the deaths of more than 1.2 million people from the Austro-Hungarian Empire, and the area of modern Austria's population dropped by almost 400,000 people between 1916 and 1920. In the years preceding the First World War, Slavic nationalism and tensions between various ethnicities in the empire had escalated to a new level; following the dissolution of Austria-Hungary in 1918, new states such as Poland, Czechoslovakia and Yugoslavia were created for corresponding ethnic groups, while Austrian and Hungarian states were created for ethnic Germans and Magyars respectively (Austria still uses this border today). The Treaty of Versailles had forbidden Austria from joining Germany, however in 1938, German Chancellor Adolf Hitler (who was born in Austria) united the two nations as part of the German Third Reich, with overwhelming support by the people of Austria. In the next few years, Austria's population decreased slightly, as a result of the forced relocation of Jews and the outbreak of the Second World War. Due to the Austria-German union, separate records were not kept for Austrian and German deaths during the war, however most estimates put Austria's total at over 350,000 fatalities.

Post-war Austria

Following Germany's defeat, Austria was split into four separately administered sections, and then the Second Austrian Republic was established in 1955, declaring its permanent neutrality in foreign affairs. In the period after this Austria has enjoyed a period of continued prosperity with a high standard of living and reasonable economic growth. Population growth stagnated in the 80's with the legalization of abortion and improved access to contraception, but has grown steadily in the past three decades. Austria is consistently ranked among the top 20 richest countries in the world in terms of GDP per capita, and in 2018 it was ranked 20th in the world by the Human Development Index.

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...

In 2023, there were around 12 million employed people with a migration background living in Germany. According to the source, a person is considered as having a migration background when they or at least one parent do not have German citizenship by law. This definition includes the following:1. Immigrated and non-immigrated foreigners.2. Immigrated and non-immigrated naturalized citizens.3. Late emigrants.4. Descendants born with German citizenship within the three groups named above.

In the past four centuries, the population of the United States has grown from a recorded 350 people around the Jamestown colony of Virginia in 1610, to an estimated 331 million people in 2020. The pre-colonization populations of the indigenous peoples of the Americas have proven difficult for historians to estimate, as their numbers decreased rapidly following the introduction of European diseases (namely smallpox, plague and influenza). Native Americans were also omitted from most censuses conducted before the twentieth century, therefore the actual population of what we now know as the United States would have been much higher than the official census data from before 1800, but it is unclear by how much. Population growth in the colonies throughout the eighteenth century has primarily been attributed to migration from the British Isles and the Transatlantic slave trade; however it is also difficult to assert the ethnic-makeup of the population in these years as accurate migration records were not kept until after the 1820s, at which point the importation of slaves had also been illegalized. Nineteenth century In the year 1800, it is estimated that the population across the present-day United States was around six million people, with the population in the 16 admitted states numbering at 5.3 million. Migration to the United States began to happen on a large scale in the mid-nineteenth century, with the first major waves coming from Ireland, Britain and Germany. In some aspects, this wave of mass migration balanced out the demographic impacts of the American Civil War, which was the deadliest war in U.S. history with approximately 620 thousand fatalities between 1861 and 1865. The civil war also resulted in the emancipation of around four million slaves across the south; many of whose ancestors would take part in the Great Northern Migration in the early 1900s, which saw around six million black Americans migrate away from the south in one of the largest demographic shifts in U.S. history. By the end of the nineteenth century, improvements in transport technology and increasing economic opportunities saw migration to the United States increase further, particularly from southern and Eastern Europe, and in the first decade of the 1900s the number of migrants to the U.S. exceeded one million people in some years. Twentieth and twenty-first century The U.S. population has grown steadily throughout the past 120 years, reaching one hundred million in the 1910s, two hundred million in the 1960s, and three hundred million in 2007. In the past century, the U.S. established itself as a global superpower, with the world's largest economy (by nominal GDP) and most powerful military. Involvement in foreign wars has resulted in over 620,000 further U.S. fatalities since the Civil War, and migration fell drastically during the World Wars and Great Depression; however the population continuously grew in these years as the total fertility rate remained above two births per woman, and life expectancy increased (except during the Spanish Flu pandemic of 1918).

Since the Second World War, Latin America has replaced Europe as the most common point of origin for migrants, with Hispanic populations growing rapidly across the south and border states. Because of this, the proportion of non-Hispanic whites, which has been the most dominant ethnicity in the U.S. since records began, has dropped more rapidly in recent decades. Ethnic minorities also have a much higher birth rate than non-Hispanic whites, further contributing to this decline, and the share of non-Hispanic whites is expected to fall below fifty percent of the U.S. population by the mid-2000s. In 2020, the United States has the third-largest population in the world (after China and India), and the population is expected to reach four hundred million in the 2050s.

The Holocaust was the systematic extermination of Europe's Jewish population in the Second World War, during which time, up to six million Jews were murdered as part of Nazi Germany's "Final Solution to the Jewish Question". In the context of the Second World War, the term "Holocaust" is traditionally used to reference the genocide of Europe's Jews, although this coincided with the Nazi regime's genocide and ethnic cleansing of an additional eleven million people deemed "undesirable" due to their ethnicity, beliefs, disability or sexuality (among others). During the Holocaust, Poland's Jewish population suffered the largest number of fatalities, with approximately three million deaths. Additionally, at least one million Jews were murdered in the Soviet Union, while Hungary, Latvia, Lithuania, the Netherlands and Yugoslavia also lost the majority of their respective pre-war Jewish populations. The Holocaust in Poland In the interwar period, Europe's Jewish population was concentrated in the east, with roughly one third living in Poland; this can be traced back to the Middle Ages, when thousands of Jews flocked to Eastern Europe to escape persecution. At the outbreak of the Second World War, it is estimated that there were 3.4 million Jews living in Poland, which was approximately ten percent of the total population. Following the German invasion of Poland, Nazi authorities then segregated Jews in ghettos across most large towns and cities, and expanded their network of concentration camps throughout the country. In the ghettos, civilians were deprived of food, and hundreds of thousands died due to disease and starvation; while prison labor was implemented under extreme conditions in concentration camps to fuel the German war effort. In Poland, six extermination camps were also operational between December 1941 and January 1945, which saw the mass extermination of approximately 2.7 million people over the next three years (including many non-Poles, imported from other regions of Europe). While concentration camps housed prisoners of all backgrounds, extermination camps were purpose-built for the elimination of the Jewish race, and over 90% of their victims were Jewish. The majority of the victims in these extermination camps were executed by poison gas, although disease, starvation and overworking were also common causes of death. In addition to the camps and ghettos, SS death squads (Einsatzgruppen) and local collaborators also committed widespread atrocities across Eastern Europe. While the majority of these atrocities took place in the Balkan, Baltic and Soviet regions, they were still prevalent in Poland (particularly during the liquidation of the ghettos), and the Einsatzgruppen alone are estimated to have killed up to 1.3 million Jews throughout the Holocaust. By early 1945, Soviet forces had largely expelled the German armies from Poland and liberated the concentration and extermination camps; by this time, Poland had lost roughly ninety percent of its pre-war Jewish population, and suffered approximately three million further civilian and military deaths. By 1991, Poland's Jewish population was estimated to be just 15 thousand people, while there were fewer than two thousand Jews recorded as living in Poland in 2018.

This graph shows the distribution of nationalities among documented immigrants who arrived in the United States between 1820 and 1870. As we can see, over seven million people arrived in the US in this 50 year period, with the majority coming from Ireland, Germany and Britain. The largest groups, by far, were Irish and German, who together made up roughly two thirds of all immigrants to the US during this time. The reasons for this were because of the Irish Potato famine from 1845 to 1849, which resulted in the death or emigration of twenty to twenty five percent of the total Irish population, and a number of internal factors in Germany such as economic migration for farmers affected by industrialization, political/religious asylum, and in order to avoid conscription. One noteworthy exclusion from the information is of those transported to US as slaves, whose information was not recorded in this statistic (although the slave trade was abolished in 1808, the practice continued in the decades that followed).

Since the beginning of the 20th century, the total number of independent nation states in Europe has almost doubled, from 24 countries in 1900 to 45 today. At the beginning of this period, much of Central and Eastern Europe was split between the empires of Austria-Hungary, Germany, the Ottomans, and Russia. The dissolution of these empires in the aftermath of the First World War resulted in the restoration or creation of several independent states, such as Czechoslovakia, Poland, and Yugoslavia. During the interwar period, there were generally 33 countries in Europe, before the Second World War saw Germany and the Soviet Union annex most of the territories between them, and control of these regions swapped between the two during the remainder of the war. Germany also invaded several Western European countries, and there were fewer than 20 independent countries in Europe at the peak of the war. Post-war Europe The post-war period then saw some major restructuring of Europe's borders, and most of the defeated Axis governments fell under Allied influence. However, there was then a split between the leading Allied Powers, and the continent was divided between the east and west. The communist, eastern countries, known as the Eastern Bloc, mostly fell under the influence of the Soviet Union; whereas the West remained largely democratic and was under American influence (but to a lesser extent). Both sides of Europe prospered throughout the post-war period, but the Eastern Bloc economies eventually collapsed or stagnated, and independence movements gained more momentum. Communist regimes across Europe began collapsing in 1989, before the Soviet Union's dissolution in late 1991. Soviet dissolution resulted in the formation of 15 separate countries, seven of which were in Europe, while Yugoslavia's eventually resulted in seven new states. Post-communist separation While the borders of Western Europe remained fairly stable throughout the entire period, Eastern Europe's changed greatly. A large part of this can be attributed to cultural and historical differences between different ethnic groups in the region, who were often forced to share their lands under various empires or world powers; the fall of communism provided an opportunity for these groups to separate, but it was not always a peaceful process. This was most notable in the Yugoslav Wars in the 1990s, where some states achieved independence through violence, while others descended into it thereafter. Communism's collapse also resulted in the expansion of European integration, and many eastern countries joined the European Union in the early-2000s; this resulted in a mass exodus of economic migrants from the former-Eastern Bloc, which has had a significant demographic and economic impact on both sides of the continent. Generally, political relations across the east have improved greatly in recent years, and prosperity is growing. However, there has been a noticeable rise in authoritarian leadership across Eastern Europe, and Russian interference in foreign politics is growing; it remains to be seen what impact this will have on the stability of the region.
