ANTICYCLONES ARE ROTATING ZONES of high pressure. Most migrate across Earth's surface, guided by large-scale atmospheric circulation, but some stay or reappear in the same general area year after year. As migrating anticyclones approach, pass over, or leave an area, they cause changes in wind direction, temperature, and moisture. They are typically associated with non-stormy […]

Any creatures that live in the Kalahari must therefore either survive without relying on easy access to surface water or migrate through the area during the times when the scarce rains fall. Perhaps the most distinctive feature of the Kalahari is the way in which it blends into the larger, surrounding stretch of arid grasslands, […]

MORE MIGRANTS NEEDED New Zealand welcomes applications from people wishing to come here, whether it is to visit, study, work or live. New Zealand needs people who are 'keen to make a go of it', people with qualifications and experience, who would not be a drain on our resources. It will cost you money to […]

In his address to the Association of American Geographers in January 1937, W.H. Hobbs began a familiar historiography of 'Exploration within the Arctic Region' around the year 330 BC, when a Greek geographer named Pytheas began a 6 year voyage to the north coast of Britain. There, Pytheas heard about a land called Thule, which he then claimed to reach […]

The percentage of United States retirees who migrate abroad is very small, but given the very large population and the recent surge of international travel and communications, the absolute number is growing. The phenomenon has recently attracted a major study by the Migration Policy Institute in 2006 in Washington DC. This found that ''the US born senior population (aged […]

The first international retirement flow to attract the attention of American researchers was of Canadians to Florida, and the first to attract the attention of European population geographers was the settlement of northern European retirees in various regions of southern Europe. The latter moves began to increase rapidly during the 1960s for a host of reasons: the new democratic regimes in […]

A third interest shared by population geographers and social gerontologists has been to understand the motivations, patterns, and consequences of retirement migration. Until the 1980s, almost all such moves were within various European countries, the United States, and Australia. The settlement of estranged aristocrats and retired senior soldiers and sailors to coastal resorts and spas was evident even before the […]

Although migration researchers focus on young adults' moves, for more than 25 years, population geographers and social gerontologists have studied old age migrations and migrants. The first interest, in the 1940s, was whether moves into nursing homes or between hospitals entailed a mortality risk. By the early 1980s, Pastalan, in Rowles and Otha in 1983, was able to review 34 US […]

MIGRATION IS referred to as “any residential movement which occurs between administrative units over a given period of time,” according to geographers Paul White and Robert Woods (1980). Other scholars have defined migration as the change in the center of gravity of an individual's mobility pattern. The destinations of the mobility flows need not, themselves, […]

ALIENS OR NONCITIZENS who reside or seek to reside temporarily or permanently within the borders of a country are generally termed as immigrants. The term immigrant refers to someone who enters a country, while the word emigrant refers to someone who leaves a country. In the early times, the tendency was to look upon the […]
