Introduction

• Darby (1969, 1974) describes the economic geography of East Anglia from the 1087 Domesday census, and the 1327-34 and the 1640-1641 Subsidy tax assessments. The switch of wealth from the Uplands in the north and south, to the Lowlands in the centre, is illustrated through 55 map figures. Some are re-created here as thematic maps, using Ordnance Survey OpenData released this month under Creative Commons Attribution - ShareAlike 3.0 Unported (CC BY-SA 3.0) as detailed below.
