While precise, isolated census data for the village boundary is not readily available (often counted within the larger Pala administrative block), Bharananganam reflects the broader demographic trends of the Kottayam district. The population is characterized by a high degree of literacy, approaching universal levels, and excellent health indicators.
The community is predominantly composed of Syro-Malabar Catholics and Hindus, living in close cultural integration. Malayalam is the primary spoken language, though English is widely understood and spoken, especially among the youth and educated populace. A defining feature of the local population is the high rate of emigration; many families have members working abroad (particularly in the Middle East, Europe, and North America), which heavily influences the local income and lifestyle through remittances.
