Bukit Selambau Changes - 553 additional and 390 deleted voters

In Bukit Selambau, 553 voter ICs were added and 390 voter ICs were deleted after GE12. The most changes took place in a few modern-sounding housing areas. As expected, the largest additions are in the 21-29 age group, and largest deletions in the 71-79 age group.

Is there anything sinister in these data? Not on the 10 police IC number changes. The size of the the roughly 390-550 regular voter changes over the first 3 quarters of 2008 look normal. Only field verification can tell more. Detailed lists of additions/deletions on a voter-by-voter basis are available for field verification.

What do "Additions" and "Deletions" mean? We have a table here that list the categories under each: Supplementary Voter Lists 2008q1 and 2007q4


Table A shows that, in Bukit Selambau (N25 under P014 Merbok), between 2007 Dec 31 (gazetted on 2008 Feb 5 for GE12) and 2008 Sep 30 (gazetted on 2009 Feb 19? for by-election):

• Overall, it looks like 553 voters were added and 390 deleted.
• In reality, 10 of these additions and deletions are "illusions." These are 10 police personnel who remained, only having their IC numbering changed,
• These are examples of actual pairs of changed police IC in Bukit Selambau: R0075654>RF75654; RT007366>RFT7366; R0107927>RF107927; R0102805>RF102805
• Another 2 police voters actually retired or moved out, and were really deleted,
  
• Non-police voter additions totaled 543 during the 3 quarters, and deletions totaled 378,
• The net change was 163 additional voters over 3 quarters, increasing the total voter count to 35,140.

Table B shows:

• How many additions and deletions are grouped under each DM (Daerah Mengundi, voting districts),
• The most changes took place in the DMs of Taman Bandar Baru, Taman Ria Jaya, and Taman Ria Selatan.
• Taman Bandar Baru is where we have found a cluster of voters with house numbers, but not street names.
  
• We were worried that such non-specific addresses in what looks like modern housing estate makes it easier to hide any phantom voters. See discussion at No Street Names Despite Modern Housing in Bukit Selambau.
