If you're using Firebug, it doesn't handle asychronous callback
functions very well.

...means that you are geocoding in a tight loop. That doesn't work,
because at every iteration the "geocoder" object gets reset. You will
only ever end up with the last one running to completion.
The solutions are
(a) store the coordinates with the zipcode and its population figure
[this is **infinitely** preferable]
(b) chain each request from the callback function, so you can be sure
that each has finished before the next is initiated
(c) use an array of geocoder objects [not recommended: you could run
out of memory very quickly for a large array]
