If you have a dataset that has data by, say, UK local authority and you want to combine that data into a different, larger-scale, geography such as UK regions - you'll need a lookup table to know which region each local authority is in. If the geographies are known to the ONS, the ONS geoportal is a great place to go to get lookups. But if either of your geographies are unknown to the ONS you may need to make your own. This tool aims to help.
