As I was meddling with registrant_list_demo.php I found that the demographics were not showing up for any of my test cases. I was under the mistaken impression this data was obtained from an external server, but it is actually taken from a data dump from the nces stored on our server in a database called ‘demographics’ (go figure). The demographics data appears to be sorted by zip code. I am surmising that this data dump is requested from nces after the registration process is complete and an updated list of zip codes has been generated.
I’m sure Mr. Sweeney can provide details of this request procedure upon his return. The demographics script is working fine, but the demographics data is most likely out if date. Cari indicated the demographics data will not be needed for a few weeks.
