I had already created a thematic map application that gave information about the uncertainty surrounding ACS estimates (move your mouse over the counties). This website generates the map using API data requests. A future expansion will include parsing the variables XML file.
When I make the following request: http://thedataweb.rm.census.gov/data/2010/sf1?key=___&get=P0010001,P0010001,P0010001,P0010001,NAME&for=block+group:*&in=state:2+county:170+tract:000101 I get the following response: [["P0010001","P0010001","P0010001","P0010001","NAME","state","county","tract","block group"], ["1","620","620","620","620","Block Group 1","02","170","000101"]] Note that the order of the variable names and ...more »
I am trying to make something for all block groups in a county and noticed that I have to make separate requests for each tract. A block group looks like: ?get=P0010001&for=block+group:*&in=state:2+county:170+tract:000101 but it would be nice if we could request: ?get=P0010001,GEOID&for=block+group:*&in=state:2+county:170 so without specifying the tract. The added GEOID (just like NAME) would make make each record unique. ...more »
In another thread I read about an updated version of the available ACS tables. It would be very handy if table restrictions and Block Group availability would be included in that list. (As in Appendix E of the technical documentation http://www2.census.gov/acs2010_5yr/summaryfile/ACS_2006-2010_SF_Tech_Doc.pdf). In the XML document those restrictions could be attributes of the "concept"
Earlier I mentioned the idea for a library that would take care of filling DOM elements with data. Yesterday I created a github repository for this and committed the beginnings of such a library. To see this library in action I created a couple of examples: http://pad.human.cornell.edu/Unlisted/ACS5API/Example.html This is a table with on the left an explanation of how the right cell is defined. http://pad.human.cornell.edu/Unlisted/ACS5API/Example1.html ...more »
The ACS API includes geographic summary levels above the state level, the SF1 and SF3 API do not. I would like to see those levels added.
When I try an API call like: http://api.census.gov/data/1990/sf1?key=mykey&get=NAME&for=state:*, I get an error message stating "unknown variable 'NAME'". When I replace the 1990 with 2000 or 2010 I get the expected result.
I am working on a page drawing data from the 1990, 2000 and 2010 SF1 and noticed a lot of differences between them. Most importantly for me: - the variables that can be drawn from the Geographic header varies a lot, in 2010 only the Name, in 1990 and 2000 a whole slew of variables, including a very useful AREALAND, but NAME for one is missing in 1990 - in 2010 the list of available geographies is a lot longer than in ...more »
Will the API servers shut down if there is a federal government shutdown? And if so, what error code can we expect?
