I wondered this myself, and I haven't got a definitive answer, but<br>
seeing the locality boundary data was derived from the Australian<br>
Bureau of Statistics, I spent some time on the ABS website to try and<br>
work it out.<br>
<br>
Under the Australian Standard Geographic Classification (AGCS), a<br>
locality can be classified in one of four ways: major urban areas<br>
(urban centres with 100,000 or more people), other urban areas (those<br>
with between 1,000 and 99,999 people), rural localities (places with<br>
200-999 people), and rural balance areas (the rural remainder).<br>
<br>
I believe the "- Bal" indicates a rural balance area, that is, one<br>
with a low population (less than 200 people). This makes sense as it<br>
seems to apply to large areas with very low population density such as<br>
airports (Point Cook and Melbourne Airport).<br>
</blockquote></div><br>Thanks for doing the research. In this case I think I'm inclined to delete them when they double up on an actual suburb location, like Point Cook. That definition is pretty esoteric, and no one is going to understand them from looking at the map.<br>
<br>Any objections?<br><br>Steve<br>
