National legislatures are often called 'houses', 'senates' or 'chambers'.
The constituencies are the areas that members of the legislatures represent. They are described by electoral boundary files. Please tell us about these electoral boundary files.
Please be careful not to submit polling districts. Polling districts are the areas which define the catchment of a polling station and are usually smaller than the constituency.
Where constituencies are the same as administrative districts these can be accepted.
