Boundary-Line
Boundary-Line provides a representation of the hierarchy of administrative and electoral boundaries and their names for England, Scotland and Wales. Boundary-Line for England and Wales was initially digitised from Ordnance Survey’s boundary record sheets at 1:10 000 scale (or, in some cases, at larger scales).
Highlight social and economic trends
Public bodies release a wealth of data via data.gov.uk, census results and other sources. By illustrating your analysis on maps created with Boundary-Line, you'll be able to highlight the social and economic trends shaping changes in how we live and work.
View historical county boundaries
As an addition to the core Boundary-Line product, which is updated twice a year, you can download data showing historical county boundaries from the late 19th Century. This is ideal for historians who need to analyse old census records and archives.
A robust framework
Monitoring outcomes by area is key for public bodies. Boundary-Line gives you a robust analytical framework to ensure the right communities get the right resources.
Professional quality, free of charge
Mapped at a scale of 1:10 000, Boundary-Line is quality-assured to the same standard as our premium products. But since it's covered by the Open Government Licence (OGL), you can download it for free and use it in a wide range of ways.
