The new website Populations Past allows users to create and view maps of different demographic measures and related socio-economic indicators every 10 years between 1851 and 1911. These include fertility, childhood mortality, marriage, migration status, household compositions, age-structure, occupational status and population density. Brief explanations of each measure are included, indicating how they are calculated and explaining how they relate to other measures. Users can zoom in to a particular area on the map, and compare side by side maps of different times or measures. When large areas are viewed at once the data are displayed in Registration Districts (RDs), but the display changes to Registration Sub-Districts (RSDs) when the users are zoomed in.
The Resources tab on the website contains a handy User Guide, as well as several podcasts of interviews with census experts created in partnership with Year 8 students from South Wales, resources for teachers, an image gallery and a number of links to online National RSD Maps.
The website is hosted by the University of Cambridge and Populations Past and its associated research project, An Atlas of Victorian Fertility Decline, have been funded by the Economic and Social Research Council and the Isaac Newton Trust (Cambridge).
