This study assesses the political acceptability of metropolitan governance in Grand Nokoué through a census survey of 18 elected officials from its five municipalities. Descriptive statistics, Wilson intervals and Borda ranking were used. Seventeen respondents support a metropolitan area (94.4%; 95% CI [74.2 99.0]), and 16 would accept at least a partial transfer of powers (88.9%; 95% CI [67.2-96.9]). Economic development (77.8%), spatial planning (61.1%) and environmental management (55.6%) are the most frequently selected functions. Political divergence is the main barrier (94.4%), while Cotonou's dominance (72.2%) and loss of municipal autonomy (61.1%) remain major concerns. The findings support a metropolitan authority with targeted powers, mixed representation, transparent financing and explicit territorial-equity safeguards. The evidence is descriptive and does not establish a causal effect of prior cooperation
