Question: How many of the people who started the great Slav migration live in the formerly Portuguese-governed country on the continent that has most of the world's lithium?

<P0-S0> today the most of american wolners come from the norwegian name wølner. <P0-S1> the most wolners now live in the u.s. and canada, and most of them have ancestors from norway after some of the norwegian wolners migrated to north america around the start of the 20th century. <SEP> <P1-S0> As of 2015, most of the world's lithium production is in South America, where lithium - containing brine is extracted from underground pools and concentrated by solar evaporation. <P1-S1> The standard extraction technique is to evaporate water from brine. <P1-S2> Each batch takes from 18 to 24 months. <SEP> <P2-S0> 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. <P2-S1> 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. <P2-S2> Perhaps some Slavs migrated with the movement of the Vandals to Iberia and north Africa. <SEP> <P3-S0> for the next ten years, there was a steady exodus of puritans from england, with about 20,000 people emigrating to massachusetts and the neighboring colonies during the great migration. <P3-S1> many ministers reacted to the repressive religious policies of england, making the trip with their congregations, among whom were john cotton, roger williams, thomas hooker, and others. <P3-S2> religious divisions and the need for additional land prompted a number of new settlements that resulted in connecticut colony (by hooker) and the colony of rhode island and providence plantations (by williams and others). <P3-S3> minister john wheelwright was banished in the wake of the antinomian controversy (like anne hutchinson), and he moved north to found exeter, new hampshire. <SEP> <P4-S0> Although the royal family returned to Portugal in 1821, the interlude led to a growing desire for independence amongst Brazilians. <P4-S1> In 1822, the son of Dom João VI, then prince - regent Dom Pedro I, proclaimed the independence of Brazil on September 7, 1822, and was crowned Emperor of the new Empire of Brazil. <P4-S2> Unlike the Spanish colonies of South America, Brazil's independence was achieved without significant bloodshed. <SEP> <P5-S0> People of German origin are found in various places around the globe. <P5-S1> 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. <P5-S2> Brazil is the second largest with 5 million people claiming German ancestry. <P5-S3> Other significant centres are Canada, Argentina, South Africa and France each accounting for at least 1 million. <P5-S4> 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.
