Vechiul Regat
The 1930 census was the only one to cover Greater Romania. Censuses in 1948, 1956, 1966, 1977, 1992, 2002 and 2011 covered Romania's present-day territory. All but the 1948 census, which asked about mother tongue, had a question on ethnicity. Moldavia and Wallachia each held a census in 1859. The Romanian Old Kingdom (Regat) conducted statistical estimates in 1884, 1889 and 1894, and held censuses in 1899 and 1912. Ion Antonescu's regime also held two: a general one in April 1941, and one for those with "Jewish blood" in May 1942.
