Interdisciplinary Urban Sociology of Municipal Burial Plot Perpetual Renewal Fee Arrears and Family Grave Abandonment in Accra's Cemetery Wards: A Bunching Estimation of Renewal Thresholds

Municipal cemeteries in Accra operate a perpetual renewal fee system in which families must pay an annual charge to retain exclusive rights to a burial plot, yet cemetery wards record widespread arrears and visible grave abandonment. Because no observational data on Accra's cemetery fee records are available, the study characterises the operating characteristics of the proposed design under a declared variance structure. A before-after-control-impact design with 8, 16, 24, and 32 clusters, effect sizes of 3, 5, and 8 percentage points, and 2,000 replications per cell was evaluated. The intraclass correlation was 0.64, between-cluster standard deviation 6.0, and residual standard deviation 4.5. Power analysis indicates that 54 clusters are required to detect a 5-percentage-point effect at 80% power. Bunching estimation offers a credible strategy for identifying behavioural thresholds in cemetery fee compliance, but that the clustered structure of cemetery wards imposes severe power constraints that must be addressed through careful design. The contribution is a transferable methodological framework for studying quasi-voluntary municipal fee regimes in data-scarce urban contexts.
