Abstract: From independence (1960) to date, the Nigeria Nation has served as a political game-arena for two different political regimes, namely democratic regime and the military regime. As an adage goes, a woman who has married two men is in a better position to know, which is manlier. To this extent, the objective of this study is to carry out a statistical investigation on the Nigerian system (which has experienced both democracy and military regimes) to determine which regime has brought greater level of economic growth. Statistical time-trend analyses are applied to some Nigerian economic growth variables. Eleven economic growth variables such as gross domestic product per capita, food production per capita and discomfort index were used. The results show that seven out of the eleven variables indicate better performance during democracy compared to military rule, while both regimes performed abysmally in the remaining four variables. It is therefore recommended that for greater economic growth Nigeria should continue to embrace democracy and that well articulated macroeconomic policies to encourage economic growth variables such as non-oil export trade, foreign direct private investment, food production etc, should be made in democratic and good governance settings.
