The data cover the period 1881 to 1911.

Sources:

  1. These data were obtained from table "WU01UK - Location of usual residence and place of work by sex" for Local Authorities from the 2011 Census of Population. The data was downloaded on 12th November 2015 in spreadsheet format from the Census part of the Topics section on the Neighbourhood Statistics website operated by the Office for National Statistics. The data are under Crown Copyright, but are made available for use under an Open Government Licence.


Notes:

  1. The data contained a caveat about accuracy due to data protection. This may affect results from the check sums: "In order to protect against disclosure of personal information from the 2011 Census, there has been swapping of records in the Census database between different geographic areas, and so some counts will be affected. In the main, the greatest effects will be at the lowest geographies, since the record swapping is targeted towards those households with unusual characteristics in small areas. More details on the ONS Census disclosure control strategy may be found at Census Results / Statistical Disclosure Control.
  2. This dataset covers the whole of the UK including Northern Ireland.
  3. The original data was downloaded as three separate data matrices (Males, Females and All Persons) with local authority of residence identified in rows and local authority where employed identified in columns, producing 404 columns by 404 rows of data for each dataset. This data was loaded into a temporary table and then converted into a simplified table with a single count per row and a distinct row for each relationship between the local authority of residence and the place of work, resulting in 489,648 rows of data (404 x 404 x 3) in the final table.
  4. Northern Ireland Local Authorities have not yet been added to the AUO gazetteer. Therefore any data relating to them have no g_unit or g_rel_to_unit values.


Checking:

  1. The statistical data have not been checked.
  2. The geographical units have been cross-checked against the GBHGIS administrative unit gazetteer to ensure that all units are correctly identified. The unit names and types have been standardised. Each unit has a unique unit ID assigned to it and this can be used to cross-reference against other data-sets.
