Comment(by woodbri):

 [a somewhat off topic response]

 Making Tiger better is somewhat problematic because you would want a
 process that feeds back into Census, but they have restrictions on what
 they are allowed to have. But I assume some stuff could go back to them. I
 thought about building a crowd sourced site to improve tiger and I think
 you can pretty easily build a "changes" database that would allow you to
 apply changes to incoming Tiger data but only if Census has not modified
 it. You would build a table structure something like:

 {{{
 file_or_table_name | uid | field_name | old_value | new_value | userid |
 timestamp
 }}}

 Then you only apply changes if the old value matches the Tiger data and
 you can report if something has changed and needs to be reviewed. And you
 have the obvious issues of multiple people entering conflict input, etc.

 It would be great if there was an open collection of parcel data, but even
 if you could collect it at the county level means you have to deal with
 about 3300 counties and convince them to open up that data. If you had to
 go to every town and municipality it would take forever. Since this data
 is in theory open public record data via the tax roles, it should be do
 able if you could get enough volunteers.
