Question: How many people who started the great Slav migration live in the colonial holding governed by Portugal on the continent from which a significant amount of cargo enters MIA?

<P0-S0> Miami International Airport and PortMiami are among the nation's busiest ports of entry, especially for cargo from South America and the Caribbean. <P0-S1> The Port of Miami is the world's busiest cruise port, and MIA is the busiest airport in Florida, and the largest gateway between the United States and Latin America. <P0-S2> Additionally, the city has the largest concentration of international banks in the country, primarily along Brickell Avenue in Brickell, Miami's financial district. <P0-S3> Due to its strength in international business, finance and trade, many international banks have offices in Downtown such as Espírito Santo Financial Group, which has its U.S. headquarters in Miami. <P0-S4> Miami was also the host city of the 2003 Free Trade Area of the Americas negotiations, and is one of the leading candidates to become the trading bloc's headquarters. <SEP> <P1-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. <P1-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. <P1-S2> Perhaps some Slavs migrated with the movement of the Vandals to Iberia and north Africa. <SEP> <P2-S0> People of German origin are found in various places around the globe. <P2-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. <P2-S2> Brazil is the second largest with 5 million people claiming German ancestry. <P2-S3> Other significant centres are Canada, Argentina, South Africa and France each accounting for at least 1 million. <P2-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. <SEP> <P3-S0> Although the royal family returned to Portugal in 1821, the interlude led to a growing desire for independence amongst Brazilians. <P3-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. <P3-S2> Unlike the Spanish colonies of South America, Brazil's independence was achieved without significant bloodshed. <SEP> <P4-S0> at the time of the berlin conference, africa contained one-fifth of the world’s population living in one-quarter of the world’s land area. <P4-S1> however, from europe's perspective, they were dividing an unknown continent. <P4-S2> european countries established a few coastal colonies in africa by the mid-nineteenth century, which included cape colony (great britain), angola (portugal), and algeria (france), but until the late nineteenth century europe largely traded with free african states without feeling the need for territorial possession. <P4-S3> until the 1880s most of africa remained unchartered, with western maps from the period generally showing blank spaces for the continent’s interior. <SEP> <P5-S0> the population of paris today is lower than its historical peak of 2.9 million in 1921. the principal reasons were a significant decline in household size, and a dramatic migration of residents to the suburbs between 1962 and 1975. factors in the migration included de-industrialisation, high rent, the gentrification of many inner quarters, the transformation of living space into offices, and greater affluence among working families. <P5-S1> the city's population loss came to an end in the 21st century; the population estimate of july 2004 showed a population increase for the first time since 1954, and the population reached 2,234,000 by 2009.
