In its classic form, bocage is found in Brittany, where small fields are surrounded by drainage ditches and high earthen banks, from which grow impenetrable hedges arching over narrow sunken lanes. Similarly enclosed land is found elsewhere, however, notably on the northern, western, and southern fringes of the Paris Basin, such as in Normandy, as well as in the western and northern parts of the Massif Central, parts of Aquitaine, and the Pyrenean region. At higher levels hedges may be replaced by stone walls. Settlement mostly takes the form of hamlets and isolated farms. Open-field

The greatest extent of open-field land is found in the Paris Basin and in northern and eastern France, but there are pockets of it elsewhere. The landscape typically lacks hedges or fences; instead, the bewildering pattern of small strips and blocks of land is defined by small boundary stones. The land of one farmer may be dispersed in parcels scattered over a wide area. The land is predominantly arable, and the farmsteads are traditionally grouped into villages, which may be irregularly clustered or, as in Lorraine, linear in form. Mediterranean

The generally block-shaped Mediterranean lowland parcels normally are not enclosed or are enclosed only by rough stone banks. However, in areas where delicate crops would be exposed to wind damage, there are screens of willows and tall reeds. Hillsides are frequently terraced, although much of this land type has been abandoned except in areas of intensive cultivation, such as the flower-growing region around Grasse. A very large farmhouse built on three floors is characteristic of wine-growing and sheep-raising regions, such as Provence. Rural population was formerly often clustered at high elevations, both for defense and in order to be above the malarial plains. In modern times there has been a move to more convenient lowland locations.

In the high mountains and especially in the Alps, there is the contrast between the adrets, the sunny and cultivated valley slopes, and the ubacs, the cold and humid slopes covered with forests. The variety of vegetation on the slopes of the mountains is remarkable. Cultivated fields and grasslands are found in the depths of the valleys, followed in ascending order by orchards on the first sunny embankments, then forests, Alpine pastures, bare rocks, and, finally, permanent snow. A unique aspect of the mountain environment is that Alpine villages of the lower valley sides were often combined with chalets (burons in the Massif Central), temporary dwellings used by those tending flocks on summer pastures above the tree line. Postwar transformation

After World War II the French government instituted a program of consolidation, whereby the scattered parcels of individual farmers were grouped into larger blocks that would accommodate heavier, mechanized cultivation. Initially progress was greatest in the open-field areas, particularly the Paris Basin, where there were few physical obstacles to the process. Subsequent extension to bocage areas had more severe consequences for landscape values and ecology, as hedges, sunken lanes, and ponds disappeared in favour of a new open landscape. At the same time, the vast numbers of people abandoning agricultural pursuits enormously changed the nature of rural settlement. Particularly in the more attractive areas, abandoned farms were purchased as second homes or for retirement. Where alternative employment was available, rural people stayed and became commuters, transforming barns and stables for other uses, such as garages. On the fringes of the expanding city regions, new houses and housing subdivisions for urban commuters were built in the villages, markedly changing their character. Urban settlement

MarseilleThe Old Port of Marseille, France.© Digital Vision/Getty ImagesThe primacy of Paris as the predominant urban centre of France is well known. After World War II the French government had an ambivalent attitude toward the development of the urban structure. On the one hand there was the desire to see Paris emerge as the effective capital of Europe, and on the other there was the policy of creating “métropoles d’equilibre,” through which cities such as Lille, Bordeaux, and Marseille would become growth poles of regional development. Even more evident was the unplanned urbanization of small and medium-size towns related to spontaneous industrial decentralization from Paris, such as that along the Loire valley, or to retirement migration, such as that along the coastlands of southern France.

Demographic trends Population history

In 1801 France was the most populous nation in Europe, containing about one-sixth of the continent’s inhabitants. By 1936 the French population had increased by 50 percent, but in the same period the number of people in Italy and Germany had nearly trebled, and in the United Kingdom and the Netherlands the population had nearly quadrupled. The marked difference in population growth between France and some of its neighbours up to the 1940s was attributed to a falling birth rate. At the same time, the mortality rate in France began its decline somewhat later than in other advanced European countries, not falling until the close of the 19th century. The birth rate was particularly affected by the practice of French peasants who deliberately limited their families in order to reduce the effect of a Napoleonic law that required the splitting of the family holdings among all heirs. Other factors may have included the rise of bourgeois individualism following the French Revolution of 1789, the decline of Roman Catholic observance (especially among the political left), and the lack of economic opportunity in the interwar years. Population growth was, of course, adversely affected by wars, including the wars of the Revolution; the wars of the First Empire; the Franco-German War (1870–71); World War I (1914–18), which cost France more than 1,500,000 lives; and World War II (1939–45), which reduced the population by 600,000.

The deficit in national growth was so drastic by 1938 that France began to give monetary and other material benefits to families with children. The policy appears to have been effective, because a rise in the birth rate occurred even during the difficult years of Nazi occupation and Vichy France, culminating in the postwar baby boom years, when soldiers and prisoners returned to a climate of economic optimism. The relative youth and high fertility of immigrants also contributed to the upsurge in the birth rate, which was coupled with a decline in mortality rates, attributable to improved public health facilities and social welfare programs.

In the second half of the 20th century, the high birth rate slowed, and about 1974 it fell into a sharp decline, eventually reaching a point insufficient for the long-term maintenance of the population. Since midcentury, because of a corresponding decline in the death rate, the rate of natural increase (balance of births against deaths) has remained positive, though in decline. By the early 21st century, France had an average population increase of roughly 300,000 people each year. These changes were not exceptional to France; the same postwar pattern was largely paralleled in neighbouring countries. A number of factors combined to reduce the birth rate, among them the introduction of the contraceptive pill and the new preference for smaller families. Emigration
