Heterogeneity in the determinants of local self-employment growth by gender, age and selected industry
Disparités régionales ; Emploi ; Esprit d'entreprise ; Etats-Unis ; Genre ; Groupe d'âge ; Industrie ; Secteur industriel ; Services aux entreprises ; Structure industrielle ; Travail indépendant
This study explores the determinants of self-employment growth across US regions and by gender, agegroup and industry. It finds that self-employment growth was faster for women than for men; that growth in the 45–64-year agegroup outpaced growth
in the age 20–44-year group; and that growth was much faster in professional and business services than in healthcare. The regression results suggest that there is significant heterogeneity in the impact of regional characteristics on self-employment growth

Une analyse des données des cinq recensements de 1971 à 1991 montre les évolutions pas toujours régulières de l'âge moyen des agriculteurs ainsi que des changements dans la distribution par groupes d'âges des cinq catégories d'agriculteurs

Etude des soldes migratoires par groupes d'âges entre 1980 et 1990 dans les comtés d'une région des Etats-Unis en croissance (Etats de Washington et Oregon). Proposition d'une typologie de ces comtés mettant en relief les structures démographiques

ESR ages of Middle Pleistocene corals from the Ryukyu Islands in XIII INQUA Congress issue.
Electron spin resonance ages of 11 corals from the lower part of the Ryukyu Group, Japan can be classified into two groups (about 600,000 and 800,000 yr). The result indicates that the lower part of the Ryukyu Group is correlated to at least two
of the oxygen isotope stages 15, 17, 19, 21 and 23. Lowermost part of the Ryukyu Group was probably deposited during a large transgression and may be correlated worldwide.
Although the crude death rates of the most important causes of death show an increase until 1964, after age-adjustment it is possible to divide these in two groups. The first group shows after age-adjustment a decreasing trend suggesting crude
mortality increases appear mostly in the oldest age-groups. The second group consists of mortality causes which after age-adjustment continue to increase. The evolution of the total cancer mortality shows that until 1940, it was dominated by the first group
, while after 1950 a switch to the second group can be noticed.
Population ageing in Germany and Poland : a comparison of regional developments in the 1990s
Agegroup ; Comparative study ; Demography ; Germany ; Poland ; Population ; Population ageing ; Population growth ; Regional development ; Urbanization
The authors show common trends of ageing for Poland and Germany, important regional variations, but also some different developments. In both countries, the process of ageing was well on the way with particular rapid developments in regions
of deindustrialisation, out-migration, and population decrease. A major determinant is the sharp fertility decline after the process of ageing could especially be observed for East Germany and Poland. In both territories new suburbanization is connected
with the relatively low degree of ageing, whereas 1990s. By contrast, West-German cities had a different development. Ageing was already relatively high in 1991, but the growth rates remained under-proportional. - (IfL)

The out-migration from Eastern to Western Germany from 1991 to 2004 is analysed. The focus lies on its age-selectivity, i.e. the diverse age-composition of migration by direction and intensity. After an overview on the migration flows between
Eastern and Western Germany the age-selectivity is analysed regarding time, sex and space. A simulation of the age-structural effects of the Eastern German out-migration closes the analysis. - (IfL)

The AA. show that if data for functional metropolitan-centered regions are employed, and if origin-destination specific streams of movement are analysed, the age-specific patterns of inter-metropolitan migration within the United States cluster

Age-sex structure of Slovenians in Vojvodina in the second half of 20th and on the beggining of 21st century
methods and mathematics proceedings are used to compare different parameters of age structure (e.g. middle age, index of ageing etc). The paper confirms that Slovenians are one of the oldest ethnic groups in Vojvodina population. Results will enrich
Age-sex structure of Slovenians in Vojvodina is elaborated in this paper. Particular attention was given to the period after the World War Second. Identification of tendencies in age structure of Slovenians was the main task of the paper. Statistic

Emigration has, especially in the last 30 years, markedly negativly influenced the courses of the demographic development of Hrvatsko zagorje. The consequence of such a demographic exodus of the region is a disturbed age and sex balance
of the population. the changes of age and sex structure of the population of Zagorje from 1961-1991 are one of the factors that negatively influences natural growth trends and intensification of depopulation.
