As a county, Cumbria has an area of 676,780 hectares, and is the second largest in area in the country.
Most datasets are available at this level and it may be a good starting point when gathering information. However, as Cumbria is a diverse county, it may be worth gathering statistics broken down at lower levels of geography in addition to county figures.
