The mortality rates of two Hungarian settlements with different levels of fluoride concentration in the drinking water are compared for the period 1966-1979. No variations in mortality are observed between the two communities. (summary in ENG, GER, RUS)

Geographic variations in mortality from malignant tumors in the Slovak regions of Czechoslovakia are examined for the period 1968-1977 by sex. The highest rates are shown to be in the western part of the region and in the two large cities. The value of small-area analysis is emphasized. (summary in ENG, GER, RUS)

Regional data for France are used to develop a regression model of the relationship between mortality by cause and tobacco consumption. An attempt is made to evaluate tobacco consumption by age and sex and to measure the importance of the statistical link between mortality and tobacco consumption. The study is based on 1968-1970 data on mortality by cause, sex, and age and 1969 data on general tobacco consumption (SUMMARY IN ENG, GER)

The author examines a method of producing annual Cuban population estimates according to age and sex for the period 1970 to 1985. He suggests that this type of demographic estimation is useful when a relatively uncomplicated procedure is desired and very precise values are not necessary (SUMMARY IN ENG, FRE, GER,)

The authors attempt to measure the statistical linkage between mortality by cause (broken down according to sex and age) and both tobacco and alcohol consumption. A model is constructed based on the results of previous studies in which tobacco and alcohol were considered separately. Data are for France for the period 1968-1970. (summary in ENG, GER)

The authors examine the various factors associated with the decline in infant mortality in Cuba between 1970 and 1979. Variations in infant mortality by province, causes of death, and the role of infant health services are discussed. (summary in ENG, FRE, GER, )

The author examines trends in perinatal mortality in selected countries over the past 10 years. Some international comparisons are made, particularly regarding the contrast between the progress made by industrialized countries in further reducing already low levels of perinatal mortality and the lack of progress in developing countries. The inadequacies of available data are noted, and the high rate of mortality decline in Cuba is discussed. (summary in ENG, FRE, GER, )

"This study is an attempt to measure the meaning of the inter-regional movements of population in Algeria during a long period of time (1897-1977). As in the whole of the Mediterranean countries, these movements have resulted in rebalancing the differences in density between mountains and plains. Nevertheless, as a result of demographic growth, the population in the mountains is much denser than it was in 1897. And the populations moving from the mountains have not settled equally in the different types of plains: coastal plains, and amongst them chiefly Algiers, received most of it." (summary in ENG, GER)

Developments in survey techniques that have occurred in France since the end of World War II are reviewed, with an emphasis on improvements in the availability of demographic data. The author describes changes in vital statistics, the development of permanent surveys, and specific surveys carried out since 1970. Some consideration is also given to plans for future surveys. (SUMMARY IN ENG AND GER)

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)
