The Economist, on the global death of the mandatory census

Now this centuries-old tradition is slowly coming to an end. If statisticians in Britain get their way, for instance, the census planned for next year could be the country’s last. Instead, they are considering gathering information from the vast, centralised databases held by government, such as tax records, benefit databases, electoral lists and school rolls, as well as periodic polling of a sample of the population. It is a global trend, pioneered, inevitably, in Scandinavia. Denmark has been keeping track of its citizens without a traditional census for decades; Sweden, Norway, Finland and Slovenia, among others, have similar systems. Germany will adopt the approach for its next count, also due in 2011.”
