American Community Survey Data via FTP. I got talking to some people from the US Census at NICAR today and asked them if there was a way to download their data in bulk (in addition to their various APIs)... and there was!

I had heard of the American Community Survey but I hadn’t realized that it’s gathered on a yearly basis, as a 5% sample compared to the full every-ten-years census. It’s only been running for ten years, and there’s around a year long lead time on the survey becoming available.

On the Anonymity of Home/Work Location Pairs. Most people can be uniquely identified by the rough location of their home combined with the rough location of their work. US Census data shows that 5% of people can be uniquely identified by this combination even at just census tract level (1,500 people).
