Question: How many people who started the great migration of the Slavs live in the country where most of our coffee comes from?

full_context: Document 1: Slavs: Around the 6th century, Slavs appeared on Byzantine borders in great numbers.[page needed] The Byzantine records note that grass would not regrow in places where the Slavs had marched through, so great were their numbers. After a military movement even the Peloponnese and Asia Minor were reported to have Slavic settlements. This southern movement has traditionally been seen as an invasive expansion. By the end of the 6th century, Slavs had settled the Eastern Alps regions.

Document 3: Germans: Persons who speak German as their first language, look German and whose families have lived in Germany for generations are considered "most German", followed by categories of diminishing Germanness such as Aussiedler (people of German ancestry whose families have lived in Eastern Europe but who have returned to Germany), Restdeutsche (people living in lands that have historically belonged to Germany but which is currently outside of Germany), Auswanderer (people whose families have emigrated from Germany and who still speak German), German speakers in German-speaking nations such as Austrians, and finally people of German emigrant background who no longer speak German.
Document 4: Slavs: The Gorals of southern Poland and northern Slovakia are partially descended from Romance-speaking Vlachs who migrated into the region from the 14th to 17th centuries and were absorbed into the local population. The population of Moravian Wallachia also descend of this population.
Document 5: Slavs: According to eastern homeland theory, prior to becoming known to the Roman world, Slavic-speaking tribes were part of the many multi-ethnic confederacies of Eurasia – such as the Sarmatian, Hun and Gothic empires. The Slavs emerged from obscurity when the westward movement of Germans in the 5th and 6th centuries CE (thought to be in conjunction with the movement of peoples from Siberia and Eastern Europe: Huns, and later Avars and Bulgars) started the great migration of the Slavs, who settled the lands abandoned by Germanic tribes fleeing the Huns and their allies: westward into the country between the Oder and the Elbe-Saale line; southward into Bohemia, Moravia, much of present-day Austria, the Pannonian plain and the Balkans; and northward along the upper Dnieper river. Perhaps some Slavs migrated with the movement of the Vandals to Iberia and north Africa.
Document 6: Coffee production in India: Coffee production in India is dominated in the hill tracts of South Indian states, with Karnataka accounting for 71%, followed by Kerala with 21% and Tamil Nadu (5% of overall production with 8,200 tonnes). Indian coffee is said to be the finest coffee grown in the shade rather than direct sunlight anywhere in the world. There are about 250,000 coffee growers in the country; 98% of them are small growers. As of 2009, Indian coffee made up just 4.5% of the global production. Almost 80% of Indian coffee is exported; 70% is bound for Germany, Russia, Spain, Belgium, Slovenia, United States, Japan, Greece, Netherlands and France. Italy accounts for 29% of the exports. Most of the export is shipped through the Suez Canal.
Document 7: Germans: People of German origin are found in various places around the globe. United States is home to approximately 50 million German Americans or one third of the German diaspora, making it the largest centre of German-descended people outside Germany. Brazil is the second largest with 5 million people claiming German ancestry. Other significant centres are Canada, Argentina, South Africa and France each accounting for at least 1 million. While the exact number of German-descended people is difficult to calculate, the available data makes it safe to claim the number is exceeding 100 million people.
Document 8: Coffee: Brazil remains the largest coffee exporting nation, however Vietnam tripled its exports between 1995 and 1999 and became a major producer of robusta seeds. Indonesia is the third - largest coffee exporter overall and the largest producer of washed arabica coffee. Organic Honduran coffee is a rapidly growing emerging commodity owing to the Honduran climate and rich soil.
Document 9: Germans: Of approximately 100 million native speakers of German in the world, roughly 80 million consider themselves Germans.[citation needed] There are an additional 80 million people of German ancestry mainly in the United States, Brazil (mainly in the South Region of the country), Argentina, Canada, South Africa, the post-Soviet states (mainly in Russia and Kazakhstan), and France, each accounting for at least 1 million.[note 2] Thus, the total number of Germans lies somewhere between 100 and more than 150 million, depending on the criteria applied (native speakers, single-ancestry ethnic Germans, partial German ancestry, etc.).

Document 11: German Americans: There is a ``German belt ''that extends all the way across the United States, from eastern Pennsylvania to the Oregon coast. Pennsylvania has the largest population of German - Americans in the U.S. and is home to one of the group's original settlements, Germantown (Philadelphia), founded in 1683 and the birthplace of the American antislavery movement in 1688, as well as the revolutionary Battle of Germantown. The state of Pennsylvania has 3.5 million people of German ancestry.

Document 13: Middle Ages: The invasions brought new ethnic groups to Europe, although some regions received a larger influx of new peoples than others. In Gaul for instance, the invaders settled much more extensively in the north-east than in the south-west. Slavic peoples settled in Central and Eastern Europe and the Balkan Peninsula. The settlement of peoples was accompanied by changes in languages. The Latin of the Western Roman Empire was gradually replaced by languages based on, but distinct from, Latin, collectively known as Romance languages. These changes from Latin to the new languages took many centuries. Greek remained the language of the Byzantine Empire, but the migrations of the Slavs added Slavonic languages to Eastern Europe.
Document 14: Coffee: Coffee is a brewed drink prepared from roasted coffee beans, which are the seeds of berries from the Coffea plant. The genus Coffea is native to tropical Africa (specifically having its origin in Ethiopia and Sudan) and Madagascar, the Comoros, Mauritius, and Réunion in the Indian Ocean. The plant was exported from Africa to countries around the world. Coffee plants are now cultivated in over 70 countries, primarily in the equatorial regions of the Americas, Southeast Asia, India, and Africa. The two most commonly grown are the highly regarded arabica, and the less sophisticated but stronger and hardier robusta. Once ripe, coffee berries are picked, processed, and dried. Dried coffee seeds (referred to as beans) are roasted to varying degrees, depending on the desired flavor. Roasted beans are ground and brewed with near - boiling water to produce coffee as a beverage.
Document 15: German Americans: None of the German states had American colonies. In the 1670s, the first significant groups of German immigrants arrived in the British colonies, settling primarily in Pennsylvania, New York, and Virginia. Immigration continued in very large numbers during the 19th century, with eight million arrivals from Germany. Between 1820 and 1870 over seven and a half million German immigrants came to the United States -- more than doubling the entire population of the country. By 2010, their population grew to 49.8 million immigrants, reflecting a jump of 6 million people since 2000.
