## What is its value?

Boundary-Line creates value for customers in a variety of ways including:

1. Highlighting 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.
2. 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.
3. 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.
