Penanti centenerians already cleaned out in August 2008

We analyze voter age groups and changes. The largest voter age group in Penanti is the 40-49 year-old group. SPR had deleted all 100+ year-old voters just before the August 2008 Permatang Pauh by-election.

Apparently to avoid embarrassment during the August 2008 Permatang Pauh by-election, SPR had deleted all 100-year-old voters in a cleaning overdrive by 2008 Jul 31. See our report here: Permatang Pauh Lost 25 Centenarians. Did SPR follow proper procedure?

We are able to make two pairs of comparison because we have three sets of voter data for Penanti:

1. 2008 Feb 05-gazetted data for GE12,
2. 2008 Jul 31 data under Permatang Pauh by-election, and
   
3. 2009 Apr 16 data under the current Penanti by-election.
   

Table A compares Sets 1 and 2, while Table B compares sets 2 and 3.

Tables A and B show that:

• The largest age group for voters in Penanti are 40-49 year-olds,
• The second largest group are 30-39 year-olds.
• The SPR deleted voters aged 100 and older, across the board, before 2008 Jul 31 data (in Table A),
• Since then, SPR has no need to delete any centenerians (inTable B),
• Table A's net decrease in voters, despite 6 months of newly-registered voters, indicated SPR was aggressively deleting voters by 2008 Jul 31, probably to avoid embarrassing anomalies before the high-profile Permatang Pauh by-election.
• Net voter increased only by 4 between the Permatang Pau and Penanti by-elections (in Table B).
