Mother’s pensions provide insight into a number of related research areas. I am particularly interested in the relationships between maternalism, social welfare policy, and citizenship in the Progressive Era. For example, what range of purposes were reformers hoping to achieve with the pensions? What public and private organizations were involved? How do varying geographic, political, and cultural influences shape the development and practice of mother’s aid? Whereas Maine was in the middle chronologically with its 1917 mother’s pension legislation, and boasted some of the highest per capita spending on mother’s aid in the United States, New Brunswick was one of the last provinces to enact legislation in 1930 (finally implemented in 1943) and had much stricter eligibility requirements. The New Brunswick pensions have been totally unexplored, and my research includes the campaign for the pensions, implementation, and changes over time due to cultural and economic fluctuations. A comparative approach to maternal and child welfare aid reveals the critical role of centralized state power, as in Maine, and county-based governmental structures, as in New Brunswick, in determining the adoption of mother’s aid programs. The decentralized nature of state-sponsored aid in New Brunswick may be a key factor in the late appearance of mother’s aid in New Brunswick. Further, the Native American experience relating to mother’s pensions has been completely unexplored in both the United States and Canada. My cross-border comparison highlights the varying perceptions and treatment of Anglophone, Francophone, and First Nation women and families in Maine and New Brunswick.
