Due to migration in the 1960s, Viseu suffered a great decline in its population. After the end of the Portuguese Colonial War (1961–1974), with the return of refugees from the Portuguese African colonies that achieved independence, and resulting economic and demographic growth, starting at the end of the 1970s, the municipality increased its population by about 10 percent, giving it an estimated population of 83,261 people. Afterwards, a stagnation set in, confirmed by the 1991 census which showed a population of 83,601.
