I'm trying to build a voting district database (MYSQL) that will allow
users to enter an address and find their district.

I have the definitions of the districts - towns and census blocks. How
do I match a address to the census block? I've been through the census
site and found an address search but no definition of boundaries.
Basically I want to recreate their address search but output my
content based on census block.

I do not want to create a map.

Could you find any help on this, I have a similar problem of selecting
an area on the map and getting all the street addresses contained
within. No help so far //

Can't you use geocoding to get the coordinates of an address and then
perform a spatial query using the geometry of the point in the census
block polygon layer? You can then use reverse-geocoding to get the
addresses from the coordinates.

Or am I over-simplifying the problem?
