The settlement has a mixed population of predominantly Berta and Nuer communities, along with smaller numbers of Gumuz and Oromo peoples. Recent censuses estimate the population to be between 3,000 and 5,000 residents, although figures are difficult to verify due to limited census coverage in the area. Arabic and Amharic are widely used as lingua franca, with Berta being the most commonly spoken local language.
Kurmuk's economy is primarily agricultural, focusing on subsistence farming and pastoralism. Crops such as maize, millet, and sorghum are cultivated, while livestock including cattle, goats, and sheep provide additional income. The town also serves as a minor trading post for cross‑border commerce with Sudan, facilitating the exchange of goods such as salt, coffee beans, and textiles.
Historically, Kurmuk has been notable for its role in Ethiopian–Sudanese border conflicts. In the late 19th century, the area was the site of clashes between forces loyal to Emperor Menelik II and the Mahdist movement in Sudan. During the 1978 Ethiopian Civil War, the town experienced brief occupations by various militias, reflecting its strategic position near the frontier. In more recent years, the area has been affected by sporadic insurgent activity and security disputes, though the Ethiopian government has implemented measures to improve stability and local governance.
The town hosts a small health clinic and a primary school, but access to secondary and higher education requires travel to Gambela or larger towns in the region. Infrastructure development remains limited, with most households relying on deep wells and community wells for water. Renewable energy projects are emerging, with some households adopting solar panels to supplement traditional fuel sources.
Kurmuk continues to develop slowly, as efforts by regional authorities aim to improve road connectivity, agricultural extension services, and cross‑border trade regulations. Despite these challenges, the community remains resilient, maintaining traditional cultural practices while gradually integrating into the broader economic framework of Ethiopia.
