 Aging, demographic fragility and population decline in the Bas-Saint-Laurent region 
Like the rest of the province of Quebec, the Bas-Saint-Laurent is affected by the increasing number (gerontogrowth) and proportion (aging at the top) of elderly people. The substantial decrease in the number (juvenile-decline) and proportion (ageing from below) of young people are two phenomena of even greater concern within the region, whose population is declining. The objective of this article is to examine the spatial configuration of territorial disparities with respect to the evolution of the four aforementioned forms of aging in the Bas-Saint-Laurent and its demographic trajectory between 1986 and 2016. Our typological analysis reveals that nearly three-quarters of the communities in the Bas-Saint-Laurent have a worrisome demographic situation, with twelve of them calling for urgent action by the State to promote better occupation of the land.
