Query: What is the population of Austria in 2018?
Austria's population was estimated to be nearly 9 million (8.83) in 2018 by the Statistik Austria. The population of the capital, Vienna, exceeds 1.8 million (2.6 million, including the suburbs), representing about a quarter of the country's population. It is known for its cultural offerings and high standard of living.
In 2001, about 74% of Austria's population were registered as Roman Catholic, while about 5% considered themselves Protestants. Austrian Christians, both Catholic and Protestant, are obliged to pay a mandatory membership fee (calculated by income—about 1%) to their church; this payment is called "Kirchenbeitrag" ("Ecclesiastical/Church contribution"). Since the second half of the 20th century, the number of adherents and churchgoers has declined. Data for 2018 from the Austrian Roman Catholic Church list 5,050,000 members, or 56.9% of the total Austrian population. Sunday church attendance was 605,828 or 7% of the total Austrian population in 2015. The Lutheran church also recorded a loss of 74,421 adherents between 2001 and 2016.
Austrian immigrants who came to Argentina did during the two great migratory waves, i.e., about the First and Second World War. The main settlement sites were Buenos Aires, Córdoba and Misiones; in the south, cities like San Carlos de Bariloche and San Martin de los Andes were among the main destinations for Austrians. The amount has never exactly been relieved and there are mostly estimates. In the early thirties, there were approximately 240,000 German-speaking people of whom 45,000 resided in Buenos Aires, and since about 9,000 were of Austrian descent. These figures are similar to those recorded in the Austrian Embassy, approximately 7,000 people of Austrian descent in Buenos Aires, considering the probability of being greater. Since the mid-nineteenth century there had been established a German-speaking colony in the neighbourhood of Belgrano, Buenos Aires. The Austrian and Swiss residents in Buenos Aires were integrated into this colony by the language and cultural affinity in general. This neighbourhood was very attractive to new immigrants since it already had adequate infrastructure, as churches, cafes and bakeries in German families that had arisen due to the former colony. Argentina is, ethnographically, the Latin American country with the largest number of immigrants and descendants of Austrian immigrants (second ranks Brazil and Uruguay in the third) with Córdoba as home to the main Austrian community, which is the province with the largest immigrant population of both German and Austrian descent in the country.
Historically, Austrians were regarded as ethnic Germans and viewed themselves as such. Austria was part of the Holy Roman Empire and the German Confederation until the Austro-Prussian war in 1866 which resulted in Prussia expelling Austria from the Confederation. Thus, when Germany was founded as a nation-state in 1871, Austria was not a part of it. In 1867, Austria was reformed into the Austro-Hungarian Empire. After the collapse of the Austro-Hungarian Empire in 1918 at the end of World War I, Austria was reduced to a rump state and adopted and briefly used the name the Republic of German-Austria ("Republik Deutschösterreich") in an attempt for union with the Republic of Germany, but was forbidden due to the Treaty of Saint-Germain-en-Laye (1919). The First Austrian Republic was founded in 1919. The Third Reich annexed Austria with the "Anschluss" in 1938.
As of 2016, the total population of Afghanistan is around 33,332,025, which includes the 3 million Afghan nationals living in both Pakistan and Iran. Afghanistan's Central Statistics Organization (CSO) stated in 2011 that the total number of Afghans living inside Afghanistan was about 26 million and by 2017 it reached 29.2 million. Of this, 15 million are males and 14.2 million are females. About 22% of the population is urbanite and the remaining 78% live in rural areas.
Austria was dominated by the House of Habsburg and House of Habsburg-Lorraine ("Haus Österreich") from 1273 to 1918. In 1808, when Emperor Francis II of Austria dissolved the Holy Roman Empire, Austria became the Austrian Empire, and was also part of the German Confederation until the Austro-Prussian War of 1866. In 1867, Austria formed a dual monarchy with Hungary: the Austro-Hungarian Empire (1867–1918). When this empire collapsed after the end of World War I in 1918, Austria was reduced to the main, mostly German-speaking areas of the empire (its current frontiers), and adopted the name The Republic of German-Austria. However the union and name were forbidden by the Allies at the Treaty of Versailles. This led to the creation of the First Austrian Republic (1918-1933).
Since the territory understood by the term 'Austria' underwent drastic changes over time, dealing with a "History of Austria" raises a number of questions, eg., whether it is confined to the current or former Republic of Austria, or extends also to all lands formerly ruled by the rulers of Austria. Furthermore, should an Austrian history include the period 1938–1945, when it nominally did not exist? Of the lands now part of the second Republic of Austria, many were added over time – only two of the nine provinces or "Bundesländer" (Lower Austria and Upper Austria) are strictly 'Austria', while other parts of its former sovereign territory are now part of countries like e.g., Italy, Hungary or the Czech Republic. Accordingly, within Austria there are also regionally and temporally varying affinities to adjacent countries.
Meanwhile, on November 12, 1918, the Provisional National Assembly of German Austria declared the country a republic. On April 3, 1919 the Constitutional National Assembly elected in February passed the Hapsburg Law which stipulated members of the former ruling family could only live in Austria if they cancelled their membership to the Habsburg Dynasty with its monarchial aspirations and if they declared themselves loyal citizens of the republic. Maximilian obviously preferred to live outside of Austria, following the example of the last imperial couple.
Hinduism is a minority religion in Austria,constituting about 0.15% of the population of Austria. Hinduism is not one of the 16 recognised religion in Austria.The Austrian law allows religious groups not recognized as societies to seek official status 
as confessional communities with the Office for Religious Affairs.Hinduism is one of the eight confessional 
communities in Austria.However the Sahaja Yoga and the International Society for Krishna Consciousness are categorised as associations, not as a confessional community.
The population of Afghanistan was estimated in 2017 at 29.2 million. Of this, 15 million are males and 14.2 million females. About 22% of them are urbanite and the remaining 78% live in rural areas. An additional 3 million or so Afghans are temporarily housed in neighboring Pakistan and Iran, most of whom were born and raised in those two countries. This makes the total Afghan population at around 33,332,025, and its current growth rate is 2.34%.
The ADL (Anti-Defamation League) published on 2015 the "ADL Global 100", an international survey conducted in 2013-2014 to measure antisemitic opinions in 100 countries around the world. The survey revealed that 28% of the adult population in Austria harbor antisemitic opinions, as reflected through the DATA: More than 50% of the population expressed agreement with the phrase "Jews still talk too much about what happened to them in the Holocaust", and more than 40% of the population agreed with "Jews are more loyal to Israel than to this country" and "Jews have too much power in international financial markets".

The only city in Afghanistan with over 1 million population is its capital, Kabul. The rest are smaller cities and towns. According to the CIA, an estimated total number of people living inside Afghanistan was 31,822,848. Of this, around 6 million or so were reported to be living in urban areas and the rest in rural or countryside.
The Protestant Reformation spread from northern Germany to Austria. By the Council of Trent in 1545, almost half of the Austrian population had converted to Lutheranism, while a much smaller minority also endorsed Calvinism. Eastern Austria was more affected by this phenomenon than western Austria. After 1545, Austria was recatholicized in the Counter Reformation. The Habsburgs imposed a strict regime to restore the influence of the Catholic Church among Austrians and their campaign proved successful; the Habsburgs for a long time viewed themselves as the vanguard of Catholicism, while all the other Christian confessions and religions were repressed.
The status of South Tyrol was a lingering problem between Austria and Italy until it was officially settled by the 1980s with a great degree of autonomy being granted to it by the Italian national government. Between 1918 and 1919, Austria was known as the State of German Austria (). Not only did the Entente powers forbid German Austria to unite with Germany, but they also rejected the name German Austria in the peace treaty to be signed; it was, therefore, changed to Republic of Austria in late 1919.
Austria was greatly affected by the Protestant Reformation, to a point where a significant part of the population became Protestant. Lutheranism was the most successful Protestant confession; that was the case among other German-speaking populations across the Holy Roman Empire and Austria was indeed one of them. Calvinism did not receive that much support. The prominent position of the Habsburgs in the Counter-Reformation, however, saw Protestantism all but wiped out beginning in 1545, restoring Catholicism as the dominant religion once more.
Berlin (; ) is the capital and largest city of Germany by both area and population. Its 3,723,914 (2018) inhabitants make it the second most populous city proper of the European Union after London. The city is one of Germany's 16 federal states. It is surrounded by the state of Brandenburg, and contiguous with its capital, Potsdam. The two cities are at the center of the Berlin/Brandenburg Metropolitan Region, which is, with 6,004,857 (2015) inhabitants and an area of 30,370 square km, Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main regions.
The Treaty of Saint-Germain of 1919 (for Hungary the Treaty of Trianon of 1920) confirmed and consolidated the new order of Central Europe which to a great extent had been established in November 1918, creating new states and altering others. The German-speaking parts of Austria which had been part of Austria-Hungary were reduced to a rump state named The Republic of German-Austria (German: "Republik Deutschösterreich"). The desire for "Anschluss" (annexation of Austria to Germany) was a popular opinion shared by all social circles in both Austria and Germany. On 12 November, German-Austria was declared a republic, and named Social Democrat Karl Renner as provisional chancellor. On the same day it drafted a provisional constitution that stated that "German-Austria is a democratic republic" (Article 1) and "German-Austria is an integral part of the German reich" (Article 2). The Treaty of Saint Germain and the Treaty of Versailles explicitly forbid union between Austria and Germany. The treaties also forced German-Austria to rename itself as "Republic of Austria" which consequently led to the first Austrian Republic.
Finland's population is 5.52 million (2018), and the majority of the population is concentrated in the southern region. 88.7% of the population is Finnish and speaks Finnish, a Uralic language unrelated to the Scandinavian languages; next come the Finland-Swedes (5.3%). Finland is the eighth-largest country in Europe and the most sparsely populated country in the European Union. The sovereign state is a parliamentary republic with a central government based in the capital city of Helsinki, local governments in 311 municipalities, and one autonomous region, the Åland Islands. Over 1.4 million people live in the Greater Helsinki metropolitan area, which produces one third of the country's GDP.
330,000,000 people lived in Europe in 1916. In 1950 there were 549,000,000. The population of Europe in 2015 was estimated to be 741 million according to the United Nations, which was slightly less than 11% of the world population. The precise figure depends on the exact definition of the geographic extent of Europe. The population of the European Union (EU) was 509 million as of 2015. Non-EU countries situated in Europe in their entirety account for another 94 million. Five transcontinental countries have a total of 247 million people, of which about half reside in Europe proper.
Like in the rest of Afghanistan, no exact population numbers are available. The Afghan Ministry of Rural Rehabilitation & Development (MRRD) along with UNHCR and Central Statistics Office (CSO) of Afghanistan estimates the population of the district to be around 154,618. According to AIMS and UNHCR, Tajiks make up 50% of the population, followed by Hazaras and Pashtuns, 50%.
Austria is a federal republic with a parliamentary representative democracy comprising nine federated states. The capital and largest city, with a population exceeding 1.8 million, is Vienna. Other major urban areas of Austria include Graz, Linz, Salzburg and Innsbruck. Austria is consistently ranked as one of the richest countries in the world by per capita GDP terms. The country has developed a high standard of living and in 2018 was ranked 20th in the world for its Human Development Index. The republic declared its perpetual neutrality in foreign political affairs in 1955. Austria has been a member of the United Nations since 1955, joined the European Union in 1995, and is a founder of the OECD. Austria also signed the Schengen Agreement in 1995, and adopted the euro currency in 1999.
The majority of the land area in the states of Upper Austria, Lower Austria, Vienna, and Burgenland is situated in the Danube valley and thus consists almost completely of accessible and easily arable terrain. The other five states, in contrast, are located in the Alps and thus are comparatively unsuitable for agriculture. Their terrain is also relatively unfavourable to heavy industry and long-distance trade. Accordingly, the population of what now is the Republic of Austria has been concentrated in the former four states since prehistoric times. Austria's most densely populated state is the city-state of Vienna, the heart of what is Austria's only metropolitan area. Lower Austria ranks only fourth with regard to population density even though it contains Vienna's suburbs; this is due to large areas of land being predominantly agricultural. The alpine state of Tyrol, the less alpine but geographically more remote state of Carinthia, and the non-alpine but near-exclusively agricultural state of Burgenland are Austria's least densely populated states. The wealthy alpine state of Vorarlberg is something of an anomaly due to its small size, isolated location and distinct Alemannic culture.
