ABSTRACT
The new migrations mostly flow out of the Southern nations, the less developed countries (LDC), or more precisely, out of the more prosperous countries of the LDC group. Immigration into Sweden comes mostly from Finland; that into the United Kingdom comes mostly from the Commonwealth countries. Efforts to explain the international migration process have variously emphasized the factors of demography, labor markets, income levels, political and social conditions, communications, distance, and transportation. The LDC problem consists essentially of the pressure of rising population upon the available means of support. The economic dimension of mobility has advanced with widespread improvements in real incomes in many countries, even among some LDCs. The origins of the illegals are a particular problem in North-South relations, as they come overwhelmingly from LDCs. International migration that is of importance to LDCs and more developed countries must be measured in both gross terms and net terms.
