Question: What country sent the most legal immigrants to Gotham's filming location from the middle leg of the journey from England to the continent of Bamako to the Americas?

Bamako is the nation's administrative centre. The city proper is a cercle in its own right. Bamako's river port is located in nearby Koulikoro, along with a major regional trade and conference center. Locally manufactured goods include textiles, processed meat, and metal goods. Commercial fishing occurs on the Niger River. Bamako is the seventh-largest West African urban center after Lagos, Abidjan, Kano, Ibadan, Dakar, and Accra. <SEP> Ecuador, Colombia, Guyana, Peru, and Brazil were the top source countries from South America for legal immigrants to the New York City region in 2013; the Dominican Republic, Jamaica, Haiti, and Trinidad and Tobago in the Caribbean; Egypt, Ghana, and Nigeria from Africa; and El Salvador, Honduras, and Guatemala in Central America. Amidst a resurgence of Puerto Rican migration to New York City, this population had increased to approximately 1.3 million in the metropolitan area as of 2013. <SEP> mali (; ), officially the republic of mali (), is a landlocked country in west africa. mali is the eighth-largest country in africa, with an area of just over . the population of mali is /1e6 round 1 million. 67% of its population was estimated to be under the age of 25 in 2017. its capital is bamako. the sovereign state of mali consists of eight regions and its borders on the north reach deep into the middle of the sahara desert, while the country's southern part, where the majority of inhabitants live, features the niger and senegal rivers. the country's economy centers on agriculture and mining. some of mali's prominent natural resources include gold, being the third largest producer of gold in the african continent, and salt. <SEP> argentina: the torch relay leg in buenos aires, argentina, held on april 11, began with an artistic show at the lola mora amphitheatre in costanera sur. in the end of the show the mayor of buenos aires mauricio macri gave the torch to the first torchbearer, carlos espínola. the leg finished at the buenos aires riding club in the palermo district, the last torchbearer being gabriela sabatini. the 13.8 km route included landmarks like the obelisk and plaza de mayo. the day was marked by several pro-tibet protests, which included a giant banner reading "free tibet", and an alternative "human rights torch" that was lit by protesters and paraded along the route the flame was to take. most of these protests were peaceful in nature, and the torch was not impeded. chinese immigrants also turned out in support of the games, but only minor scuffles were reported between both groups. runners surrounded by rows of security carried the olympic flame past thousands of jubilant argentines in the most trouble-free torch relay in nearly a week. people showered the parade route with confetti as banks, government offices and businesses took an impromptu half-day holiday for the only latin american stop on the flame's five-continent journey. <SEP> Historically the particular routes were also shaped by the powerful influence of winds and currents during the age of sail. Returning from North America, it is easiest to follow the Gulf Stream in a northeasterly direction using the westerlies. For example, from the main trading nations of Western Europe it was much easier to sail westwards after first going south of 30 N latitude and reaching the so - called ``trade winds ''; thus arriving in the Caribbean rather than going straight west to the North American mainland. A similar triangle to this, called the volta do mar was already being used by the Portuguese, before Christopher Columbus' voyage, to sail to the Canary Islands and the Azores. Columbus simply expanded the triangle outwards, and his route became the main way for Europeans to reach, and return from, the Americas. <SEP> Filming for the first season finished on March 24, 2015.
