A descriptive cross-sectional study was carried out among 144 under-five children from rural (n=72) and urban (n=72) area in Tangail, Bangladesh. The major objective of this study was to assess and compare their socioeconomic information and nutritional status among rural and urban children. This study initiated that almost one half participants in urban area were nuclear family (<4 member) but major participants in rural area (44.5%) were contained 6-7 family member. In rural area, the occupations of household head were mainly farmer (44.4%) while more than two third were engaged themselves in business in urban areas. Anthropometric indices of weight-for- height (WHZ), weight-for-age (WAZ), height-for-age (HAZ) and Body Mass Index (BMI) for Age (BAZ) z-score were used to estimate the children's nutritional status. It was found for WHZ in rural area that 1.39% children were severely wasted, 1.39% were moderately wasted, 22.23% were mildly wasted and there were no severe overweight but in urban areas 25%, 2.78% and 1.38% were mild overweight, moderate overweight and severe overweight respectively. For WAZ, the results also stated that, the children from rural area were underweight (38.8% mildly underweight and 25% moderately underweight) rather than overweight but inverse results were found for urban children. For HAZ, the prevalence of moderately stunting among rural children (44.45%) was higher than urban children (2.78%). From BAZ, the prevalence of obesity was presented higher among the urban children. As most of the rural children were wasted, underweight and stunted, it should be provided community education concerning about nutritional knowledge, environmental sanitation and personal hygienic practices, breast-feeding and weaning practices, nutritional deficiency diseases, nutritional value of food and dietary practices would perhaps overturn the trends.
