The places where people live have been recorded in one way or another for centuries. Previously, the place of registration could have been a church, municipality government, city address board, housing board or the Population Register. In recent decades, developed countries have found that register data are usually more accurate than survey data, and so population censuses have also begun to use them. Back in 2011, eight European Union countries conducted the census on a register basis: in addition to the Nordic countries, the Netherlands, Belgium, Austria and Slovenia.
