History does repeat itself - and the census proves that. The first modern census of 1801 was called amidst fears that Britain's growing population would outstrip the country's supply of food - and 200 years later countryside and food are as topical as ever.
There have been great changes in the census itself over the last two centuries - from the at times controversial questions on the forms to the methods of collecting, storing, processing and assessing the information.
The census is rich in history - both in the questions and the answers. They reveal the changes that have taken place during what is regarded as the biggest upheaval of the population in Britain's history.
