Dema is of Latin origin, derived from the ancient Roman family name Demetrius, which means 'dedicated to Mars.' It has a distinct, yet approachable sound, making it unique yet familiar.
The name Dema experienced a notable increase in popularity between the late 19th century and the early 20th century, with significant spikes occurring during World War I (1915-1918) and post-war periods. The peak of popularity was reached in 1923 with 20 births, marking a significant departure from the earlier years where fewer than 14 births were recorded annually. However, after the 1930s, the usage of Dema began to decline steadily until it reached its lowest point in recent times (5 births in both 2019 and 2021). Despite fluctuations, the name has maintained some level of consistency with an average of approximately 4-6 births per year since the mid-20th century.
