This study discusses the application of auto-regressive integrated moving average (ARIMA) model to the study of Christian marriage data. Box, Jenkins and Reinsel procedure for fitting ARIMA model was adopted in the analysis of data after transformation. The logarithm transformation suggested by data evaluation was applied to stabilize the variance. The fitted model: Wt = 0.0495 + 0.9270et – 12 + et (Wt = Xt - Xt-12) was found to be adequate for describing the pattern in the transformed series (Xt) for the period 1989 to 2008. The forecast values for the 12 months of 2009 using this model indicates a high degree of agreement with the actual value. This model has therefore been re
