In this chapter, the limitations of the suffrage reforms of 1909–1921 are presented, and the significance of the age restriction is discussed compared to the age criteria and timing of other suffrage reforms. The uniqueness of the Swedish experience of the age criteria is presented as a background to discussing earlier Swedish and international research and methodological considerations. The fact that Sweden deviated from a general pattern in the reforms in Europe allows us to ask questions about the cultural construction of age and the economic and social background to the interest of limiting the participation of the young, unmarried, and mobile urban working-class population in the democratic reforms. The study thus identifies the need to examine how the voting age was culturally charged with meaning, the political negotiations about suffrage reforms, and the social and demographic development. This study combines an interest in the narratives and constructions of age and how these are linked to political reform and social and economic development. The issues that were discussed are still topical. Age remains a crucial dividing line in the right to vote. And the voting age is currently a subject of political debate and change.
