Filling DOM elements with Javascript based on custom tags

http://pad.human.cornell.edu/Unlisted/api_json.html Please take a look at the source. What I tried to do is creating a web page using empty DOM elements and fill them later with Javascript and API calls. The Javascript loops through all elements with class='acs5' and I use the HTML5 data-* custom tags to define what value I would like to see in that element. The browser might throw a warning because I violate same-origin ...more »

ACS Choropleth Maps

http://acsmapper.appspot.com/D3 Given the dearth of other live examples, I felt like I should post something, though I haven't been able to do a lot of necessary cleanup and polish. It was nice to be able to pull something like this together with just a few hours of work via the Census API, though. For a given ACS sub-table (anything with an _002E or higher suffix), I'm calling the data for all US counties and dividing ...more »

Campaign: Bugs / Problems

possible error in sf1.xml?

In all of the "sex by age" sets the "85 years and over" label is duplicated for female. I think the first instance is actually just "female".

 

variable name="P012A026" concept="P12A. Sex By Age (White Alone) [49]">Female: !! 85 years and over

 

variable name="P012A049" concept="P12A. Sex By Age (White Alone) [49]">Female: !! 85 years and over

Error when querying with census tract blocks

Hi, I'm trying to run the following query: http://api.census.gov/data/2010/acs5?key=[key]&get=B00001_001E&for=block:2001&in=state:04+county:015+tract:954900 I get the error message, "There was an error while running your query. We've logged the error and we'll correct it ASAP. Sorry for the inconvenience." If I run the same query but just use the census tract, it works, but if possible I would like to be able to ...more »

Campaign: API Technical Discussions

wildcarding geo values

this applies to block groups, but others as well ... '+county:*+tract:*' with acs5 is not set to operate with the * wildcarding (using the above selects the first BG in each county only) but would be immensely valuable if county and tract can accept wildcarding rather than specific values. For most users, looking up a tract code is infeasible and generally not desireable (multi tracts being the norm). Thank you and ...more »

Campaign: API Technical Discussions

Scope of geocodes

The acs5 at state level uses a gnis coding in query. maybe others do also. It is suggested that only FIPS codes, census codes (places, tracts etc), and OMB codes (cbsa etc) be used. folks are far more familiar with FIPS codes and it willl reduce a) confusion and b) Census resources to maintain a additional layer of geocodes. it might be that gnis is going to be a national standard, maybe, but we are not there now.

Campaign: Using Data

Census tracts within a radius

I am looking for a way to get the ACS data for a radius around a given point. Using the FCC's API I can get the Census Tract and Block number to use. Does anyone know of a way to get the Census tract numbers say within a 5 mile radius?

Campaign: General Feedback

Scope of subject matter insufficient

This is intended to be positive & helpful ... to Census: the scope of tables/items is insufficient to build "real" generalized applications. Too many key tables are missing (for typical users) and many of those included are relatively infrequently used. To make this "catch" with the broad developer community, the subject matter data needs expansion. For ACS 5 year data, consider first all of those tables that are ...more »

ZCTA-level data for ACS

Any chance of getting this through the API? I'm mashing up Census data with FEC campaign contribution data, and it would be really interesting to have access to attributes on education, income, etc. at the ZIP level.
