Description graphique des caractéristiques de l’évolution de la population des municipalités du Québec (1951-1971)

À partir d'une série de graphiques, les auteurs analysent les caractéristiques globales de l'évolution de la population des 1596 municipalités du Québec en considérant successivement les deux périodes décennales 1951-1961 et 1961-1971, ainsi que la période de 20 ans 1951-1971. Une première série de graphiques illustre la fréquence des pourcentages d'évolution positive ou négative. La seconde série montre les caractéristiques de l'évolution des municipalités en nombre et en population par classe de taille. Le processus de concentration de la population et du nombre de municipalités est ensuite abordé à l'aide de courbes de concentration. Enfin, l'examen des caractéristiques de l'évolution dans les blocs de municipalités d'évolution positive et négative constitue la dernière partie de l'étude.De l'ensemble dé ces analyses il ressort que, au cours des deux périodes décennales 1951-1961 et 1961-1971, on a assisté à une accentuation de la concentration de la population à l'intérieur d'un nombre toujours plus réduit de municipalités de taille moyenne ou supérieure (de 20 000 à 100 000 habitants). À l'opposé, les municipalités en état de décroissance démographique ont augmenté en nombre, mais représentent une proportion de plus en plus faible de la population du Québec. Finalement, ce sont les petites municipalités rurales de moins de 2 000 habitants qui ont connu les pertes les plus sérieuses de population. Cette recherche permet de préciser les modalités du processus d'urbanisation du Québec en rapport avec la structure dimensionnelle des municipalités.Using a series of graphs, the authors analyse the general characteristics of the evolution of the population of 1596 municipalities in Québec for two successive ten year periods (1951-61 and 1961-71) and for the entire twenty year period (1951-71). An initial set of graphs, consisting of histograms, reveal the relative frequency of recurrence of various degrees of positive and negative population change. A second set illustrates the characteristics of the evolution of the municipalities in terms of their number and population by size class. The concentration of the population is then analyzed by means of Lorentz curves. Finally, the characteristics of the demographic evolution by type of change, negative or positive, are examined.This research reveals that over the twenty year period 1951-71 the population of Québec has become more and more concentrated in an ever decreasinq number of municipalities, especially those having population between 20 000 and 100 000. By contrast, the number of municipalities suffering population losses has increased, but represents an ever decreasing proportion of the total population of Québec. It is the small rural municipalities (2 000 people or less) which have suffered the most serious losses. The work thus considers the process of urbanisation with respect to the size structure of the municipalities of Québec

Some factors affecting the distribution and apparent abundance of yellowfin and skipjack tuna in the Eastern Pacific Ocean

ENGLISH: Since 1951, the Inter-American Tropical Tuna Commission has been investigating the biology, ecology and population dynamics of the yellowfin tuna, Thunnus albacares, and the skipjack tuna, Katsuwonus pelamis, in the Eastern Pacific Ocean. Of particular importance has been the study of the effects of fishing and of fishery-independent factors on the abundance and distribution of these tunas. For yellowfin tuna there is, on the average, an inverse relationship between total fishing effort and apparent abundance (Schaefer, 1957a). For skipjack there is no evidence to suggest that fishing effort has ever been sufficiently intense to affect measurably the abundance (Schaefer, 1961). Rather, it appears that the year-to-year fluctuations in apparent abundance are independent of the activities of the fishing fleets. SPANISH: Desde 1951 la Comisión Interamericana del Atún Tropical se ha dedicado a la investigación de la biología, ecología y la dinámica de las poblaciones del atún aleta amarilla, Thunnus albacares, y del barrilete, Katsuwonus pelamis, en el Océano Pacífico del Este. De importancia especial ha sido el estudio de los efectos de la pesca y de los factores independientes de las pesquerías sobre la abundancia y la distribución de esos atunes. En cuanto al atún aleta amarilla, existe, en promedio, una relación inversa entre el esfuerzo total de pesca y la abundancia aparente (Schaefer, 1957a) . Con respecto al barrilete, no hay evidencia que haga pensar que el esfuerzo de pesca haya sido nunca lo suficientemente intenso como para afectar sensiblemente la abundancia (Schaefer, 1961). Más bien parece que las fluctuaciones de un año a otro en su abundancia aparente, son independientes de las actividades de las flotas pesqueras

1998 Census: The Results and Implications

The 1998 Census was the fifth nation-wide census to be held in Pakistan. The earlier censuses were held in 1951, 1961, 1972, and 1981. It was the British colonial administrators who started the tradition of holding nation-wide decennial censuses in the year beginning with digit 1. Regular censuses were held in British India from 1881 to 1941. Pakistan continued with this tradition and conducted its national censuses in 1951 and 1961. The 1971 census was postponed due to civil war leading to the separation of East Pakistan. But it was promptly held in the following year in 1972. The 1981 census was held on time in March 1981, preceded by the Housing Census in December 1980. The present author was the Census Commissioner at that time
