Prior to the revolution in Algeria in 1969, the infant mortality rate for the native population was markedly higher than the rate for Europeans living in Algeria and the rate did not decrease for the native population during the colonial period. For the urban native population, the infant mortality rate was 3-5 times higher than the rate for Europeans living in urban areas of Algeria during the period 1954-1960. Rural rates were probably much higher. These high rates were due to a failure on the part of the colonial powers to provide adequately for the health care needs of the native population. Since the revolution, the mortality rate for infants has declined. The mean infant mortality rate for 1954-1960 was 102.4/1000 live births while the mean rate during the 7 years following the revolution was 78.3/1000 live births. This decrease reflects the improvements made in health care services by the Algerian People's Democratic Republic. During the colonial era there was only one medical school in Algeria; now there are three; and in 1977, 823 medical school students were graduated. During the period 1963-1972, the number of hospital beds increased by 17.8% and the number of physicians increased by 55.3%. During this same period the health budget doubled and now accounts for 5-7% of the national budget. Line graphs show 1) mortality, infant mortality, and child mortality rates for European and native populations in Algeria for 1954-1960; 2) infant mortality rates by race for Algeria, 1960-1970; and 3) infant mortality rates for France and for native and European Algerian populations for 1906-1960.

The merits of a biographical approach to demographic analysis are examined using survey data. "The analysis of complex interaction between diverse phenomena, using bivariate or multivariate models has been elaborated, and it allows the discovery of various types of dependence between events (reciprocal or unilateral) or of their independence. At this stage, heterogeneity of the observed populations was introduced, with the help of parametric or semi-parametric models, which point out the different strategies followed. The problems caused by non-observed heterogeneity have been partially solved but interdisciplinary collaboration would now appear to be necessary." (SUMMARY IN ENG AND GER AND SPA)

The process of leaving the parental home on reaching adulthood is analyzed using data for two cohorts of French women, those born in 1947 and those born in 1959, who were surveyed in 1986. Two alternative ways of establishing adulthood are considered, namely, marriage and the achievement of an academic or professional qualification. The tendency of unmarried adult women to return to the family home is considered. (SUMMARY IN ENG AND GER AND SPA)

Regional differences in the rate of demographic aging in France are examined. The author notes that "contrary to popular belief, of the two factors that contribute to aging, natural trends (births and deaths) still have the edge over the effect of population migrations across regions. The only exception to this is in the Paris area, due to the influence of Paris itself, where youthfulness caused by migrations is on a more or less equal footing with 'natural' aging. Conversely, migration contributes the most to the increase in the average age in the western French regions, with the joint effects of young people leaving and the over-60s returning."

The importance of ethnicity in the economic behavior of immigrants to France is examined, with particular reference to immigrant salesmen working in the underground corridors of the Paris metro. The results indicate that having the necessary business skills and initiatives required to survive in this environment are far more important than belonging to a particular ethnic group.

"A determining factor in the demographic and employment dynamics of rural communes and certain small towns [in France] is how far they are from the nearest large town. Demographic dynamics and employment trends are somewhat adverse for those living far from urban influences. The main reasons for this would appear to be the slump in agriculture. This said, demographic and employment trends are much improved nearer the large towns, especially since the towns exerting the influence have more inhabitants." (SUMMARY IN ENG AND GER AND SPA)

"Using a certain number of hypotheses on labour efficiency, it is possible to evaluate the impact of reunification on West Germany's growth from 1988 to 1993. The additional growth generated by this increase in the labour force is approximately six points of GDP over the period. From 1989 to 1991, years during which immigration was at its height, the annual growth rate was 1.2 to 1.5 points higher than it would have been had reunification not taken place. Since 1991, this potential growth has been on the downturn and should become moderate in coming years." (SUMMARY IN ENG AND GER AND SPA)

An analysis of recent rural migrants in the city of Monterrey, Mexico, is presented. The focus of the study is on the impact of rural-urban migration on social class. The author concludes that in contrast to Europe, where the assimilation of rural migrants has been the norm, migrants in Monterrey are in the process of establishing original and distinct social and economic structures in the city.

Labor force participation in France of those aged over 55 years is analyzed in this article. "The drop in the participation rate in later years is a longterm trend found in most developed countries. It is a common method for reducing working hours over an entire life cycle and has been made possible by the growth in productivity and the development of pension schemes. However, the phenomenon grew in the mid-1970s, especially in France, due to the growth in early retirement and end-of-career unemployment and also the lowering of the legal retirement age. The participation rate in France is now very low after sixty and is one of the lowest in Europe for the 55-to-59-year-old age bracket." (SUMMARY IN ENG AND GER AND SPA)

Future trends in the size and characteristics of the population of working age in France are analyzed using data from official sources. "The future working population is expected to comprise even fewer young people and more women than today. This population should continue to grow and will probably have risen by one and a half million people by 2006, essentially for demographic reasons. The trend should subsequently reverse due to the first post-war generations reaching 60 years old. The working population should therefore start to decrease. Yet the effect of the turnaround should remain modest up to 2015." (SUMMARY IN ENG AND GER AND SPA)
