Original sentence: Because almost all of the Hungarians in the commune (98% of them) were already living in the centre of the commune, this increase in total population meant that the share of the Hungarian community decreased and the ethnic composition of the Unirea village became more similar with the ethnic composition of the Unirea commune.In terms of numbers, the Hungarian population increased from 1,084 in 1850 to a peak of 1,898 in 1910 and has been gradually declining ever since.The last census of the 20th century recorded 810 Hungarians, which means that their community declined by more than half in 80 years.The last census to record a Hungarian majority in Unirea village was the 1930 census and starting with the 1941 census, a Romanian majority has been recorded.This resulted in a swap between the Hungarian and the Roma communities as the second and the third most important ethnic groups in Unirea.Thus, while the population of some of the other villages halved, the total population of the Unirea village more than tripled.Unirea village, due to its status as centre of the commune, has been the only village whose population increased in the last 150 years.While the percentage of the Hungarian minority almost halved in the last 150 years, the percentage of the Roma minority more than doubled.While the share of the Romanian majority remained almost constant after 150 years (with a slight 5% increase), the two main minorities of the commune, the Hungarians and the Romas, have experienced opposite trends
