Doesn't get much more handicapped than this.
Christian Science is an oxymoron. There is no science coming out of the Bible, which is what you're calling 'christian science'.
Creation Science is the explanation of the Bible and how it could of happened. Even though 33% seems low it's higher than any other. You have no common sense, in the pie chart it clearly states almost every religions percentage, Christianity's percentage is higher then any other.
Since you can't read pie charts, I'll write it down here.
Christianity - 33% <Highest
Muslims - 19.6%
Hindus - 15.9%
Non-Religious - 12.7
Chinese Folk - 6.4%
Buddhists - 5.9
Ethno Religionists - 3.8%
New Religionists - 1.7%
Sikhs - 0.4%
Jews - 0.2% <Lowest
Other - 0.4%
I copied this directly from the pie chart and only combined Athiests with Non-Religious because it's the same thing. As you may notice Christianity has the highest percentage.
