Why has Glasgow and acirc and 128 and 153s economy declined causing the city to lose nearly a third of its population since the 1960s?

Glasgow's economy has declined primarily due to the collapse of its traditional industries, such as shipbuilding and manufacturing, which were once the backbone of the city's economy. This decline led to significant job losses and economic dislocation, prompting many residents to seek opportunities elsewhere. Additionally, urban decay and a lack of investment in infrastructure further exacerbated the population decline, as people moved to more prosperous areas. The city's efforts to diversify and revitalize its economy have had mixed success, contributing to ongoing challenges in retaining its population.
