The rice consumption data in Taiwan is either outdated or incomplete. The government currently estimates per person per year rice consumption based on the second-hand statistic data. It is derived form the supply side data sources. Thus there are assumptions behind the calculation and anyone unreasonable assumption might lead to biased estimate of rice consumption. This study estimates the rice consumption as well as analyzes its rice consumption behaviors in Taiwan. to do so, a rice consumption survey is implemented while the econometric and statistic approaches applied here. Geographic stratified random sampling is applied to the households in Taiwan. the estimation results show that the rice consumption amount per capita per year is about 47.28 kg which is smaller than the statistic government provides. Eating out amount is 34.16 kg while in home consumption is 13.12 kg. Since the population growth has being fast recently, this study also estimates eating out ratio. On average, the eating our ratio is 48.84%. For breakfast, only 9.89% eating out has consumed rice. It is much lower than lunch and dinner, 59.83% and 53.71%, respectively. Meanwhile, dining behavior has changed with the growing multi-culture and associated dining habits. Thus this study also estimates age-specific rice consumption structure. Youth between 11 to 20 consume most rice among all age groups.
