Ethnic Romanians constitute 89 percent of the population of Romania. Two important ethnic minorities are Hungarians (7.5 percent of the total population) and Germans (0.5 percent), both concentrated in the Transylvania region. The number of Roma (Gypsies), is officially estimated at about 400,000, but may be much higher… For more information on Hungarians, see the chapter on Hungary in Volume 4; on the Germans, see the chapter on Germany in Volume 4.
