Great Britain (1997) - Macro Variables A5005_A-A5005_E, A5006_A-A5006_E, A5010, A5026_1, and A5027_1

As indicated in the following election study note from the CSES Module 1 codebook, the sample coverage for the 1997 British General Election Study is Great Britain, not the United Kingdom.

         | ELECTION STUDY NOTE - GREAT BRITAIN (1997): A1006
         |
         | Please note that the coverage of the 1997 British General
         | Election Study is Great Britain (i.e. England, Wales and
         | Scotland) - not the United Kingdom. (The most important
         | difference being that the UK also includes Northern Ireland).

Some macro level features which refer to the United Kingdom need to be adjusted so that they refer instead to Great Britain.

The affected variables are:

A5005_A - A5005_E (PERCENT VOTE - LOWER HOUSE - PARTY A to E)
A5006_A - A5006_E (PERCENT SEATS - LOWER HOUSE - PARTY A to E)
A5010 (ELECTORAL TURNOUT)
A5026_1 (PRIMARY DISTRICTS - LOWER - 1ST SEGMENT)
A5027_1 (NUMBER OF SEATS - LOWER - 1ST SEGMENT)

Pseudo-code for making the corrections is provided below:

if A1004 = "GBR_1997" A5005_A = 44.33
if A1004 = "GBR_1997" A5005_B = 31.45
if A1004 = "GBR_1997" A5005_C = 17.19
if A1004 = "GBR_1997" A5005_D = 2.04
if A1004 = "GBR_1997" A5005_E = 0.53
if A1004 = "GBR_1997" A5006_A = 65.21
if A1004 = "GBR_1997" A5006_B = 25.74
if A1004 = "GBR_1997" A5006_C = 7.18
if A1004 = "GBR_1997" A5006_D = 0.94
if A1004 = "GBR_1997" A5006_E = 0.31
if A1004 = "GBR_1997" A5010   = 71.57
if A1004 = "GBR_1997" A5026_1 = 641
if A1004 = "GBR_1997" A5027_1 = 641

The percent of the vote was obtained for A5005_A, A5005_B and A5005_C from the UK Electoral Commission. Given that the Commission did not report vote percentages for small parties at the level of Great Britain, we sought alternative sources to supply these statistics. This information was located at: http://www.election.demon.co.uk. Here the results are disaggregated properly for vote share. This site is not an official election site for the UK, but the information found at the UK Electoral Commission in this case was consistent with the alternative site (i.e., the total amount of vote for the SNP and PC is exactly the same--both percentages and number of votes). Thus, we used this source to refill the incomplete data from the UK Electoral Commission (e.g., vote for SNP, vote for PC and voter turnout).
