UNCTAD research shows that some locations host virtually all of the top TNCs. Among developed countries, the UK, the Netherlands and the US are the preferred host countries, while Brazil leads the developing country list, with investments by 75% of the top 100 TNCs. Nearly as many, 72%, have affiliates in Mexico, 67% in Hong Kong and 65% in Singapore. South Africa leads the field among the African nations, with 43%.
About 82 developing economies host foreign affiliates from at least three of the 100 largest TNCs. Top TNCs from the US have the widest geographical spread in terms of affiliates.
