Hey smart people! We're looking to fill a really interesting role focused on measuring the quality and relevance of online content (globally). Computationally savvy social scientists or survey methodologists are a great fit. careers.microsoft.com/us/en/job/1262…

Alternatively, say you are asking people to label a document as racist or not - if everyone agrees its racist at certain point you can stop collecting data. Looking for papers with insight into these kinds of problems and coming up sort of empty handed.

Say you're trying to measure income in a population where everyone is identical, in theory you only need one survey response - but you wouldn't know everyone was identical until you collected a certain amount of data.

Does anyone know of literature on stopping criteria for an experiment, survey or crowdsourced labelling task.

On the use of census tract level data...

@darribas @gboeing @undertheraedar I have a copy of a doc from the 50's that tells the story. I think they wanted to use 160 acre grids because they were being used in the west divide up public land, but the NYC tenement commission had pre-existing zones called "sanitary areas." These were adopted became tracts

@seth_sp @gboeing @undertheraedar Ahh what a neat piece of history! I'd love to know the process that took grid cells into what we have today... the fabric of urban and political life?

For all the urbanist data geeks in the Twitterverse: what unit of analysis would you ideally use if you had to measure the built environment of cities? Buildings? Street segments? A combination? (Hex)grid cells? Admin boundaries? What is the core building block? #askingforafriend

@gboeing @undertheraedar @darribas A modern take I'd love to explore someday is the idea of a social grid. A geohashing algorithm that given a lat/long return a grid cell of a size that preserves privacy, minimizes variance in survey estimates, and whatever else...

@gboeing @undertheraedar @darribas @undertheraedar FWIW the original idea for tracts, in 1906 was to use a 160 acre grid.
