Here is some fairly recent data by those not friendly to creationism.
http://www.religioustolerance.org/ev_publid.htm
It looks like those who believe in creationism are 36%. While those who do not believe in evolution are 29%.
It is interesting to note that while falling, the percent change over the generations is not as steep as one might suspect.
There is also a graph where different denominations are polled about their belief in evolution. From Catholic = 58% to Evangelical = 23%
This might give some idea of the distribution.
