This post is merely two additions to previous posts, neither of which warranted a post on their own.
The first relates to this post from September where I talked about the idea of realtime mapping of bus services using GPS data. Better people than I had the same idea and, through the Apps4NSW competition, Flink Labs has produced this prototype for Sydney and Newcastle buses. I think it’s great. I may have anticipated the means by which it would come (Google maps and Government 2.0) but I got the timing way out – I thought it would take years. Hopefully the new government will run with it so it becomes more phone friendly.
The other relates to my speculations on the paucity of Filipino restaurants. One hypothesis I didn’t mention is that Filipino migrants might be less prone than other migrant groups to cluster into certain suburbs (the way we can see suburbs that are notably “Greek” or “Vietnamese” for instance), so that that a given restaurant would struggle to have a local returning customer base within it’s own community. This could be plausible if Filipino migrants have better English skills (due to American colonialism) and are therefore less likely to seek other speakers of their language to live near. Alternatively, the gender imbalance and associated exogamy may mean they are more geographically spread out.
I didn’t feel this hypothesis explained much (hence I didn’t mention it), but I kept it in mind. The other day I was using CData to map 2006 census data on migrant groups for an unrelated question (on which I’ll probably post in future), but this gave me the opportunity to compare Filipino settlement to some other groups. Notably I compared residency in Sydney and Melbourne by people born in the Phillipines with those born in two other countries, Korea and India. I chose these two because their periods of migration roughly coincide with Filipino migration, so they’d be facing similar house prices and job opportunities which would alter their choices relative to post war migrants. Additionally, unlike the Vietnamese or Lebanese (or more recently East Africans), there’d be no refugee aspect where settlement would be dictated by government decisions. Furthermore, Korean and Indian restaurants are abundant. The comparison is still flawed of course.
The maps (and some notes) are below the fold. I can see some element of greater concentration amongst Koreans and Indians, at least in Sydney (and in places where you’d find many restaurants in said cuisines), but not nearly enough to explain the disparity. The concentration of Filipinos in the spur of settlement between Blacktown and Penrith is notable – half the Filipino restaurants I know of in Sydney are in Blacktown (i.e two). Maybe there’s a lack of suitable commercial real estate there?
I don’t think there’s more for this hypothesis though, but you can look for yourself.
The colour thresholds were chosen by Cdata based on the variance between postcodes for that ethnicity for the entirety of NSW and Victoria. This is why they are constant in both cities but are different for each country of birth.
The Korean data presumably includes Korean adoptees, which makes the concentration in a few places (Eastwood, Lidcombe, the CBD etc.) in Sydney alone all the more striking.
