How High is Trade Union Membership Where You Live?

UnionMaps presents estimates of trade union membership and the coverage of collective pay agreements for detailed geographical areas. The figures related to union membership are derived from the Labour Force Survey, the main source of data used in the production of official statistics for union membership within the UK.  Information related to collective pay agreements is derived from the Annual Survey of Hours and Earnings.  Data are provided for the Unitary Authority and Local Authority Districts of Great Britain: there are over 400 such areas.

UnionMaps provides data based upon area of residence for the following measures:

  • Union density: The percentage of employees who are a trade union member.
  • Union presence: The percentage of employees who are a trade union member or who are employed at a workplace where others are members.
  • Union coverage: The percentage of employees who report that pay and conditions are agreed in negotiations between their employer and a trade union.
  • Collective pay agreement.  The percentage of employees whose pay is set with reference to an agreement affecting more than one employee. 

Simply click on the map or use the search tool (not available for all mobile devices) to produce area reports of union membership for a particular location. Alternatively, use ‘Map the data’ to see how the different measures of union membership vary across Great Britain.
