Census records (recensămînt) list the names of each member of a family and show ages and other valuable information for linking families. They are used in conjunction with the parish and civil registers to establish family relationships. Romania has conducted a census in each of the following years: 1912, 1930, 1941, 1956, and 1966. Austro-Hungarian censuses for Transylvania, Banat and Bukovina were taken in 1785, 1805, 1828, 1857, 1869, 1880, 1890, 1900, 1910.
Early censuses give names of heads of families. Later censuses include other household members and give ages or birth dates, places of residence, civil status, occupation, etc.
National Archives (Archivelor Statului) of Romania and National Archives of Hungary.
The Family History Library has acquired a few of the early Austro-Hungarian census records, covering parts of Transylvania. These were acquried from archives in Hungary.
