Survival in a country with few natural resources has historically induced Cape Verdeans to emigrate. In fact, of the more than 1 million people of Cape Verdean ancestry in the world, only a little more than one-third actually live on the islands. Some 500,000 people of Cape Verdean ancestry live in the United States, mainly in New England. Many people of Cape Verdean ancestry also live in Portugal, Netherlands, France, Italy, Mexico, Uruguay, Argentina, and Senegal. Cape Verdean populations also settled Spain, Germany, Canada, and other CPLP countries (Angola, Brazil and Guinea-Bissau). Since after independence from Portugal in 1975, a number of Cape Verdean students continued to be admitted every year at Portuguese high schools, polytechnical institutes and universities, through bilateral agreements between the Portuguese and Cape Verdean governments.
