The world economy | The Magic of Diasporas; Immigrant networks are a rare bright spark in the world economy. Rich countries should welcome them. Economist, Nov 19, 2011.

Quote:

"There are now 215m first-generation migrants around the world: that’s 3% of the world’s population. If they were a nation, it would be a little larger than Brazil. There are more Chinese people living outside China than there are French people in France. Some 22m Indians are scattered all over the globe. Small concentrations of ethnic and linguistic groups have always been found in surprising places—Lebanese in west Africa, Japanese in Brazil and Welsh in Patagonia, for instance—but they have been joined by newer ones, such as west Africans in southern China.

"A Harvard Business School study shows that American companies that employ lots of ethnic Chinese people find it much easier to set up in China without a joint venture with a local firm.

My comment:
(a) There is no need to read the rest.
(b) According to 2011 CIA World Factbook, population of Brazil and France is 203.4m (fifth largest in the world) and 65.3m, respectively (both July 2011 est.).

(2) Immigration |  Crying Wolf; The Republicans are fretting about a disappearing problem. Economist, Nov 19, 2011

(The drop in arrests reflects not laxer enforcement, but stronger. There are over 17,000 Border Patrol agents on the border with Mexico, a fivefold increase over 1993. They patrol in cars and all-terrain vehicles, on bicycles and horses, in boats, planes and helicopters. When there are no agents around, cameras, reconnaissance drones and three different types of sensors—seismic, magnetic and infra-red—keep tabs on things. A third of the border is fenced, and most of the rest is in areas so remote or rugged as to make fences pointless or impractical. Some parts of the fence are 17 feet high, with metal plates extending ten feet below ground to prevent tunnelling.")


(3) Diasporas  Mapping Migration; Where are the world's biggest Chinese and Indian immigrant communities? Economist, Nov 17 2011 (online only)

(Chinese in Peru: 1.3m)

Note: Chinese Peruvian
http://en.wikipedia.org/wiki/Chinese_Peruvian
(Total  1,300,000 - 1,600,000[;] 3-4% of the Peruvian population)

By contrast, Japanese Peruvians number mere 90,000. Wikipedia

Both figures surprise me.
